What Is Parylene?
Parylene is a family of polymers made from p-xylylene monomers.
It comes in several types: N, C, D, and HT (also called F). Each offers specific benefits for different uses.
- Unlike regular coatings, Parylene goes on through Chemical Vapor Deposition (CVD).
- This creates an ultra-thin film with no holes.
- It forms a perfect barrier against moisture and chemicals.
What makes Parylene special is how it’s applied.
- There’s never a liquid phase during the process.
- The polymer builds up molecule by molecule on your magnet’s surface.
- This creates a truly conformal coating with no seams and minimal stress.
The resulting layer offers great mechanical durability and electrical insulation.
These qualities make Parylene perfect for protecting sensitive magnetic materials.
How Parylene Is Applied to Neodymium Magnets
Unlike regular plating or liquid coatings, Parylene goes on through a unique chemical vapor process at room temperature.
The coating forms directly on the magnet without ever becoming liquid.
The process works in several steps:
Surface Preparation
NdFeB magnets need pre-plated surfaces (like nickel) or thorough cleaning. This includes solvent rinses or plasma cleaning to remove dirt and oxide layers. This step matters – any contamination can cause adhesion problems.
Adhesion Promotion
A silane coupling agent (usually A-174) is applied to bond the Parylene to the surface. This agent creates chemical links between the metal and the polymer. Without this step, the Parylene might not stick properly to smooth metal surfaces.
Sublimation
The solid Parylene powder is heated to about 150°C and turned to vapor under vacuum.
Pyrolysis
The vapor moves to a high-temperature zone (650-700°C) where it breaks into reactive gas molecules.
Deposition
These molecules enter a chamber where magnets are kept at room temperature. The gas deposits and forms chains on every exposed surface. The polymer literally “grows” on the magnet molecule by molecule until it reaches the desired thickness.
Post-Deposition Curing
While Parylene is typically ready after deposition, some processes include a brief post-cure to ensure complete polymerization and maximize adhesion.
This gas-phase approach creates an exceptionally even coating that reaches into tiny cracks, pores, and edges.
- The vapor can penetrate gaps as small as 0.01 mm.
Because the polymer forms from vapor, the coating has no seams and minimal stress. It needs no additives or catalysts, resulting in extremely high purity. The result is a clear plastic film that’s chemically inert, biologically stable, and tightly adherent.
Types of Parylene and Their Properties
Several Parylene types exist, each with unique benefits for magnet protection:
Parylene N
This is the basic form with a completely linear, hydrogen-only structure. It gets into tiny spaces better due to its smaller molecule size. With the highest dielectric strength, it’s ideal for filling fine cracks or pores on magnet surfaces. While it has a high melting point (420°C), it works best at lower temperatures (around 60°C in air) because it lacks chlorine that improves heat stability. It stays stable even at extremely cold temperatures, making it great for space or low-temperature uses. Parylene N deposits more slowly than other types but can reach extremely tight spaces most effectively.
Parylene C
The most widely used type, featuring one chlorine atom per molecule. It deposits faster than N and creates an extremely low permeability coating. This workhorse variant efficiently blocks moisture, corrosive gases, and chemicals. It can protect components for 10+ years even in harsh environments and easily passes 100-hour salt fog tests with no damage. Works reliably up to 80°C continuously in air, with brief exposure to 100°C. Beyond 80°C, especially with oxygen present, it will slowly break down over long periods. A Parylene C coating just 0.5 μm thick is typically completely pinhole-free, providing exceptional protection even at minimal thickness.
Parylene D
A version with two chlorine atoms that offers improved high-temperature stability. The additional chlorine allows it to handle higher sustained temperatures around 100°C continuously, with short-term use to 120°C. In oxygen-rich environments, it has shown to protect components at 100°C for 10 years reliably. The trade-offs include slower deposition and slightly reduced ability to coat deep crevices compared to types C or N, as the larger molecules don’t penetrate as well. Aside from thermal endurance, Parylene D shares Parylene C’s strong moisture and chemical resistance. It’s used mainly for automotive or industrial electronics that experience elevated temperatures.
Parylene HT (Parylene F)
Specialized coating designed for extreme temperature and UV resistance. Contains fluorine atoms that significantly raise temperature limits. Can handle continuous service temperatures up to 250-350°C, with short-term exposure to 450°C. Its melting point exceeds 500°C. Also offers improved UV stability, making it suitable for outdoor applications where standard Parylenes would degrade from sun exposure. While it has slightly lower tensile strength than other variants, it remains robust. The most expensive type (significantly higher cost than Parylene C), used only when extreme conditions demand it, such as in engine compartments or space applications.
- For most neodymium magnet applications, Parylene C provides the best balance of performance and cost.
- It is the “go-to coating” for most applications due to its excellent barrier performance and versatility.
Key Advantages of Parylene for Neodymium Magnets
Perfect Coverage with Minimal Thickness
The vapor process ensures even thickness on all surfaces—corners, edges, and crevices—something often hard to achieve with liquid or electroplating methods.
- Standard Parylene coating thickness for corrosion protection typically ranges from 5-25 microns (μm).
- Even at just 0.5 μm (0.0005 mm), Parylene forms a continuous, pinhole-free film if applied correctly.
Thickness can be uniformly controlled in the micron range with tight tolerances. Typical production achieves ±20% tolerance, while optimized processes can reach ±5% precision. This control ensures all surfaces have consistent protection with no weak spots.
This exceptionally thin yet effective barrier maintains your magnet’s dimensions while providing complete protection. For precision or tiny magnets used in micro-medical devices where added weight or size must be minimal, Parylene’s ultra-thin yet protective nature is unmatched. The coating reaches hard-to-coat edges, corners, and complex shapes with consistent thickness. This truly conformal coverage ensures equal protection on all sides.
Superior Moisture and Chemical Barrier
Parylene has an extremely low water vapor transmission rate, making it one of the most effective barriers against moisture and chemical attack. A properly applied coating acts as a nearly impermeable barrier to water vapor and corrosive agents.
The hydrophobic nature of Parylene repels moisture. It effectively blocks salt spray, sweat, high humidity, and other corrosive environments. A Parylene-coated NdFeB magnet can operate in 100% relative humidity or be completely submerged in water (or saltwater) for extended periods while remaining dry and corrosion-free underneath. In salt spray tests, Parylene-coated magnets show dramatic resistance to oxidation, and Parylene C coating easily passes a 100-hour salt fog test with no degradation.
Parylene doesn’t swell or degrade in water, and it prevents liquid penetration even at the microscopic level. Tests show that Parylene coatings can protect electronics against complete water immersion effectively. For magnets used in outdoor sensors, underwater acoustic devices, or medical implants, this moisture resistance is a huge benefit.
Its chemical inertness means it resists most solvents, acids, and bases at normal temperatures. Parylene-coated magnets can be exposed to fuels, oils, bodily fluids, and corrosive gases without the coating breaking down. This broad chemical resistance means a Parylene-coated magnet can be used in chemical plants, oil & gas equipment, and medical devices where contact with various chemicals is expected.
Excellent Electrical Properties
Parylene provides outstanding electrical insulation with a very high dielectric strength (7,000-8,000 volts per 25 μm film). Different Parylene types offer varying electrical properties: Parylene N has the highest dielectric strength and a dielectric constant that remains stable across high frequencies, which can be beneficial if the magnet is part of an electrical or RF device.
This exceptional insulation makes it ideal for magnets used near electronic components or in electrical systems. Unlike metal platings which conduct electricity, Parylene completely prevents electrical conduction between the magnet and surrounding components.
The coating prevents any electrical conduction or shorting if the magnet contacts coils or other conductors. It also isolates the magnet from galvanic corrosion when touching other metals. For magnets in motors or sensors where they might contact coils or other conductors, the Parylene layer eliminates any risk of electrical shorts or unintended current paths.
Biocompatibility and Purity
Parylene (especially types N and C) is biostable and biocompatible, having been used in human implantable devices for decades. It meets USP Class VI and ISO 10993 standards for biocompatibility and has FDA approval for use in implantable devices. Manufacturers have filed Device Master Files (MAFs) with the FDA documenting Parylene’s properties, making regulatory approval easier for devices using Parylene-coated components.
The coating contains no additives, solvents, or catalysts, resulting in extremely high purity. Since the deposition involves no liquid phase, the resulting film is essentially just the polymer itself, free of impurities or ionic contaminants. This purity is important for both electrical and corrosion performance—no contaminants means nothing in the coating will promote corrosion or surface leakage.
This makes it perfect for medical applications where magnets might contact skin or tissue, such as in cochlear implants, orthopedic attachments, prosthetics, or biosensors. The coating forms a barrier preventing potentially harmful elements in the magnet alloy (like Nd or B) from leaching out, ensuring the magnet won’t cause irritation or toxicity.
Parylene’s use in medical implants like pacemakers and surgical tools is well documented, making it a natural choice for magnets intended for biomedical applications. Its non-toxic, non-reactive nature makes it suitable for applications in food processing equipment or pharmaceutical manufacturing where safety standards are stringent.
Thermal Stability (within range)
Within its operating range, Parylene holds up well to heat and cold. It remains stable and doesn’t become brittle even at cryogenic temperatures near -269°C (4 K), as shown by cycling tests from cryogenic to room temperature with no loss of integrity. This makes it excellent for applications in space environments or cryogenic equipment.
Depending on the type, Parylene can work effectively in moderately high temperatures. Parylene D can protect a magnet in a 100°C environment where many other polymer coatings would fail. Even though Parylene isn’t meant for very high temperatures unless it’s the HT type, its performance from cryogenic up to 80-100°C is very reliable over long periods.
In oxygen-free or inert atmospheres, Parylene’s thermal endurance increases substantially. It can survive much higher temperatures if oxygen (which causes breakdown) is not present. This means inside a sealed enclosure or vacuum, a Parylene-coated magnet could briefly withstand temperatures a few hundred degrees higher than its normal rating.
It also has a low coefficient of thermal expansion (CTE) similar to epoxies, meaning it expands/contracts at a rate not too far from metals, reducing stress from thermal changes. This helps maintain coating integrity during thermal cycling.
Mechanical Protection and Lubricity
While thin, Parylene provides some mechanical reinforcement and protection. It can help secure small magnet pieces or stabilize a magnet within an assembly by filling tiny gaps. In electronics, Parylene is known to “ruggedize” components by mechanically stabilizing them. On a magnet, the coating might help secure small pieces or contain tiny loose particles if a chip were to form, which is beneficial for safety and cleanliness.
Once deposited with proper adhesion promoters, Parylene films adhere very well to most magnet surfaces. The coating has no internal stresses, so it tends not to crack or peel if the surface was properly prepared. This makes it quite durable even under vibration or thermal cycling—it essentially becomes part of the magnet’s surface.
Parylene has a low coefficient of friction comparable to PTFE (Teflon), with values similar to common dry lubricants. This lubricity can reduce friction if the magnet contacts other components, potentially reducing wear on both surfaces. While magnets aren’t typically used as sliding parts, this property can be beneficial in assemblies where slight movement might occur.
Depending on the type, Parylene coatings demonstrate good mechanical robustness. With proper adhesion to the substrate, these coatings can withstand normal handling, assembly operations, and operational stress without damage. For magnets used in medical devices or electronics where reliability is critical, this mechanical durability adds an important layer of protection beyond just corrosion resistance.
Environmental Performance of Parylene Coatings
Understanding how Parylene performs in different environments helps determine if it’s right for your application:
Temperature Performance
Best Performance
Parylene-coated magnets perform best in moderate to low temperature ranges. Standard Parylene C maintains its protective properties at room temperature and below, remaining stable even at cryogenic temperatures near -269°C (4 K). For typical applications:
- Parylene N: Up to 60°C continuous in air
- Parylene C: Up to 80°C continuous in air, with brief excursions to 100°C
- Parylene D: Up to 100°C continuous, with short-term exposure to 120°C
- Parylene HT: Up to 250-350°C continuous, with short-term exposure to 450°C
In vacuum or inert gas environments, temperature limits increase substantially as oxygen is the primary catalyst for polymer degradation.
Challenging Conditions
High heat with oxygen poses the greatest challenge. When standard Parylene C is exposed to temperatures above 120-150°C in air, it will begin to discolor, lose flexibility, and eventually crack. Applications like electric motors or engine compartments that routinely exceed 100°C in air are not suitable for standard Parylene coatings unless using the more expensive Parylene HT.
Humidity and Water Exposure
Best Performance
Parylene truly excels in wet and humid conditions. Its extremely low water vapor transmission rate and hydrophobic nature create a waterproof envelope around the magnet. Parylene-coated NdFeB magnets can operate in:
- 100% relative humidity
- Complete water submersion
- Saltwater environments
- Condensing conditions
Parylene does not swell or degrade in water, and it prevents liquid penetration even at microscopic levels.
Challenging Conditions
Few moisture conditions challenge Parylene. Potential issues might arise with high-pressure water or steam (as in autoclave sterilization at 130°C, 2 atm steam), where the combination of heat and pressure could stress the coating. Generally, Parylene handles water exposure exceptionally well as long as the coating remains intact.
Chemical Resistance
Best Performance
Parylene resists a wide range of chemicals at ambient conditions:
- Mild acids and bases
- Fuels and oils
- Organic solvents (alcohols, acetone at room temperature)
- Corrosive gases (chlorine, H₂S)
- Biofluids and disinfectants
This makes it suitable for magnets in chemical processing, oil & gas, and medical applications.
Challenging Conditions
Very strong reagents at elevated temperatures can eventually break down Parylene:
- Concentrated oxidizing acids (hot nitric or sulfuric acid)
- Chlorinated solvents at high temperature
- Strong alkalis at high temperature (boiling sodium hydroxide)
- Environments with high radiation or ozone
For most industrial, medical, or consumer chemical exposures, Parylene provides excellent protection.
UV Exposure
Best Performance
Parylene performs best in UV-light-free or low-UV environments. Indoor applications, underwater use, or situations with only occasional, indirect UV exposure pose no issues for Parylene coatings.
Challenging Conditions
Direct and prolonged UV exposure (sunlight or UV lamps) will gradually degrade standard Parylene. C and N variants will yellow under UV and become brittle over time. For outdoor applications with constant sun exposure, Parylene HT offers better resistance, or additional UV-blocking layers may be necessary.
Mechanical Stress
Best Performance
Parylene works well in environments with low to moderate mechanical stress. The coating handles normal handling, vibration, and minor impacts effectively. It can withstand thermal cycling without cracking due to its flexibility and lack of internal stress.
Challenging Conditions
Abrasive contact, sharp impacts, or significant bending stress can damage the thin Parylene layer. Applications involving sliding contact, frequent collisions, or flexing are not ideal for Parylene coatings. The coating has poor resistance to sharp objects—a knife or metal edge can easily cut or scratch it.
Comparing Parylene to Other Coating Options
When selecting protection for your neodymium magnets, consider how Parylene compares to alternatives:
Nickel Plating
Common, cost-effective, and relatively robust with good corrosion resistance. However, nickel coatings can develop microcracks or pinholes, potentially leading to corrosion points. Nickel is also slightly magnetic, which can interfere with sensitive magnetic measurements or applications. Nickel can handle higher temperatures (up to 150°C or more) than standard Parylene variants, making it suitable for high-heat applications. Often used as a base layer beneath Parylene for a “belt and suspenders” approach in critical applications.
Epoxy Resin
Provides thicker protection and good corrosion resistance. Epoxy coatings can be thicker and more economical for certain applications. However, they might be less uniform on edges and corners and can crack or chip under mechanical stress or thermal cycling. They typically don’t achieve the thin, completely conformal coverage that Parylene provides.
Gold Plating
Offers excellent conductivity and corrosion resistance but is more expensive than even Parylene in many cases. Gold is more prone to scratching or wearing off over time if not protected. It provides good protection but at a premium cost.
Zinc/Tin Plating
Cheap options but can corrode themselves in harsh environments or require passivation. These platings can be good economical choices for less demanding environments but don’t offer the same level of protection as Parylene in aggressive conditions.
Parylene stands out for its uniform, pinhole-free coverage and superior barrier properties. The coating thickness is consistent on all surfaces—even complex geometries—where liquid coatings or electroplating might thin out at edges or corners. The main trade-offs are higher cost (typically the most expensive conformal coating option) and more complex application process requiring specialized vacuum deposition equipment.
Potential Limitations of Parylene Coatings
While Parylene offers excellent protection, it’s important to understand some limitations:
Temperature Constraints
Standard Parylene (N, C, D) has relatively low maximum operating temperatures in air. Parylene C is generally limited to 80°C continuous use (100°C short-term) before deterioration begins. If exposed to excessive heat, the coating will discolor (turn yellow/brown), lose flexibility, and eventually crack.
Mechanical Vulnerability
Though Parylene has decent abrasion resistance for a polymer, it’s still a thin plastic film that can be scratched, cut, or worn through by rough handling or abrasive contact. It’s not as hard as ceramic or metal plating, making it less suitable for high-friction applications.
Processing Complexity and Cost
Applying Parylene requires specialized vacuum deposition equipment and a batch process that can be time-consuming. The raw material is expensive (hundreds to thousands of dollars per kilogram), making it significantly costlier than standard coatings. This makes Parylene typically the most expensive conformal coating option available.
Difficult Rework
Once applied, Parylene is challenging to remove or repair. It’s chemically inert, so solvents won’t easily dissolve it. Removal usually requires abrasive methods, specialized chemical strippers at high temperature, or plasma etching—methods that could damage the magnet.
Industries Benefiting from Parylene-Coated Magnets
Medical Devices
Parylene’s biocompatibility makes it ideal for implantable magnets in cochlear implants, orthopedic attachments, and biosensors. It prevents any corrosion products from entering the body and resists body fluids (saline, enzymes) that would otherwise corrode an unprotected magnet.
The coating can withstand common sterilization methods like ethylene oxide gas or gamma irradiation. It is somewhat less tolerant of autoclave (steam) due to temperature limitations, so if repeated autoclaving is needed, Parylene D or HT may be more appropriate, or autoclave cycles should be limited.
Its electrical insulation properties prevent interference with MRI imaging, unlike some metallic coatings that could cause imaging artifacts. Parylene is non-conductive and non-magnetic, avoiding these issues entirely. For magnets in MRI-compatible tools or sensors, this is a significant advantage.
Medical device engineers should ensure the coating process is done in a clean, certified manner, often requiring ISO 13485 quality systems and perhaps an FDA device master file for the coating, which reputable Parylene vendors have in place.
Electronics and Semiconductors
In consumer electronics, Parylene-coated magnets in speakers, vibration motors (found in smartphones), hard disk drive spindle motors, and sensors resist corrosion from sweat and environmental moisture. The electrical insulation prevents unintended interactions between magnets and sensitive circuitry.
If a magnet is near a PCB, coating it prevents any chance of it causing a short or interacting galvanically with traces. Parylene is already widely used as a conformal coating on circuit boards (meeting IPC-CC-830 standards), so applying it to magnets in the same assembly maintains consistency.
Parylene’s high purity ensures no ionic contamination, critical for semiconductor manufacturing equipment. Any magnets used in wafer handling robots or actuators can be coated to ensure no ions shed that could contaminate semiconductor yields. Its uniform thickness won’t interfere with tight clearances in precision devices.
Regarding magnetic cleanliness, plating materials like nickel can produce ferromagnetic debris if they flake; Parylene is non-magnetic and tends not to flake, preserving the magnetic circuit’s integrity and not attracting unwanted particles.
Aerospace and Defense
Parylene’s low outgassing properties make it NASA-approved for space applications.
- They meet ASTM E595 standards with Total Mass Loss (TML) around 0.12% and Collected Volatile Condensable Material (CVCM) near zero in tests.
Coated magnets in spacecraft won’t release particles or gases that could contaminate sensitive optical equipment or other instruments.
The coating handles cryogenic conditions without becoming brittle. It also operates effectively in vacuum with no performance degradation. In fact, Parylene can handle even higher temperatures in vacuum or inert environments since oxygen is the primary catalyst for thermal degradation.
- It meets MIL-I-46058C Type XY and IPC-CC-830 standards for conformal coatings, having proven reliability in military and aerospace systems.
For magnets in satellites, aircraft, or other aerospace applications, these certifications ensure they’ll meet the rigorous demands of those environments.
In defense applications, environmental extremes are common (think magnets in a missile guidance system or a naval sonar). Parylene’s broad protection and MIL-SPEC conformity are advantageous. It means using Parylene on magnets is not an untried idea—it has established pedigree in military and aerospace projects.
Cost-Benefit Analysis of Parylene Coating
Parylene coating is generally more expensive than alternatives due to specialized equipment, batch processing time, and raw material costs. The Parylene dimer can cost hundreds to thousands of dollars per kilogram depending on the type, with specialty types like AF-4 (Parylene HT) being particularly costly.
The deposition process is batch-oriented and time-consuming—it might take several hours to coat and then outgas parts. Labor is also involved in pre-cleaning and masking components. All these factors make Parylene the most costly conformal coating option in many cases.
However, the cost-benefit equation becomes favorable when:
- Your application requires extreme reliability over long periods (10+ years)
- Magnet failure would lead to expensive system downtime or catastrophic consequences
- The environment is highly corrosive (saltwater, chemicals, bodily fluids)
- The application is in a hard-to-service location (implanted devices, sealed systems)
- The magnet is part of a high-value medical or aerospace system
- The application requires both corrosion protection and electrical isolation
- Ultra-thin coating is necessary to maintain precise dimensions
For critical applications, the additional cost provides insurance against premature failure. In medical implants, electronics, or aerospace systems, this reliability justifies the investment. A Parylene-coated magnet in a pacemaker or satellite might cost more initially but eliminates risks that could lead to mission failure or patient harm.
Cost efficiency can be improved by:
- Coating many parts in one batch to reduce the per-unit cost
- Optimizing fixture design to maximize chamber utilization
- Specifying the minimum thickness needed for adequate protection
- Using Parylene selectively on only the most critical components
While designers are sometimes concerned that Parylene is “too expensive except for mission-critical use,” coating providers can often work within budgets by optimizing runs or suggesting design modifications.
Though more expensive initially, the extended lifespan and performance enhancements often provide greater value over time.
In extremely harsh environments, using Parylene acts as an insurance policy on your magnet’s longevity—protecting your entire system investment, not just the component cost.
Best Practices for Implementing Parylene Coatings
To get the most from Parylene coating on your neodymium magnets:
Assess the Operational Environment
Temperature range, exposure to chemicals, mechanical wear, and humidity considerations should dictate your Parylene choice. For environments below 60°C, Parylene N works well. For temperatures up to 80°C, choose Parylene C. For conditions reaching 100°C, Parylene D is appropriate. Only use Parylene HT for extreme temperatures.
Magnetization Timing
Consider coating demagnetized magnets to avoid attraction issues during the coating process. Magnets can easily attract each other or trap metal fixtures due to magnetic force during coating. They can be magnetized after coating without affecting the Parylene layer, as Parylene is non-magnetic and doesn’t interfere with magnetization.
Design for Coating
Avoid very deep blind holes or fully sealed cavities that gas can’t reach. Parylene needs line-of-sight access (via diffusion) to coat surfaces. Slightly break sharp corners on magnets with small chamfers to help the coating cover evenly and avoid thin spots at edges.
Plan for Assembly
Parylene deposition is generally one of the last steps in manufacturing because it covers everything. If the magnet needs to be soldered or bonded, this should typically be done before coating, with masking applied to areas that must remain uncoated. Masking for Parylene can be done with tapes, boots, or special fixtures, but must be very tight because the gas can penetrate tiny gaps.
Consider Multi-Layer Protection
For extreme environments, combining nickel plating with Parylene coating provides enhanced protection. This “belt and suspenders” approach offers the hardness of nickel with the pinhole-free seal of Parylene. The Ni-plated surface should be clean and slightly roughened to ensure optimal Parylene adhesion.
Thickness Selection
Choose appropriate thickness based on your application. Parylene coatings on magnets typically range between 5-20 microns. Thinner coatings (1-5 microns) might be sufficient in mild environments, while thicker films provide extra protection in harsh conditions.
Quality Testing
Verify coating quality through electrical tests (checking for pinholes by measuring insulation resistance), environmental stress tests (exposing the coated magnet to accelerated conditions), and visual inspection under magnification. These validations ensure your coating will perform as expected in real-world conditions.
