1. Applications of Parylene in the Field of Magnetic Materials
NdFeB (Neodymium Iron Boron):
Corrosion Resistance: Resistant to acids, alkalis, and organic solvents, as well as salt spray (fully coated magnetic materials show no corrosion after immersion in 7% hydrochloric acid for over 15 days).
Surface Debris Fixation: Increases the strength of the magnet and prevents particle contamination.
Complete Filling: Fills micropores and gaps completely without pinholes or other coating defects such as "fish eyes."
Soft Ferrite:
Ultra-thin Insulation Layer: Can withstand high voltage (a 22μm coating can withstand 2400V).
Micron-level Thickness: Uniform and controllable, significantly saving space for magnetic ring winding without affecting magnetic properties.
Excellent Lubrication: Provides low wear.
SmCo (Samarium Cobalt) and Other Magnetic Materials:
Conformal Coating: Adapts well to complex shapes.
Salt Spray Resistance: Exhibits excellent resistance to salt spray.
Strength Enhancement: Increases magnet strength, reducing the likelihood of breakage or fracture in thinner and more fragile products.
2. Applications of Parylene in the LED/OLED Product Field
Compared to traditional potting methods, Parylene coating is ultra-thin and lightweight, avoiding significant increases in the weight of LEDs and reducing the number of structural frameworks required to support large signs. Its excellent barrier properties and high temperature resistance protect LEDs from corrosion by corrosive liquids, fluids, gases, and chemicals during prolonged exposure to atmospheric conditions and high temperatures. Parylene coating's outstanding UV stability and optical clarity enable LEDs to withstand prolonged UV radiation without affecting their color or lumen output. With low dielectric constant and low dielectric loss, Parylene prevents absorption or loss of electronic signals during LED signal transmission. Consequently, in recent years, Parylene coating has been widely used for the protection of LED products.

3. Applications of Parylene in Silicone/Rubber Products
Silicone is a highly active adsorbent material. During the manufacturing of various silicone products, static electricity can cause them to adhere to each other, making separation difficult during handling, which poses inconvenience to operators. Additionally, silicone products are prone to dust and bacterial adhesion on their surfaces. Parylene technology employs a unique CVD method to deposit a thin, transparent Parylene film on the surface of silicone products. This Parylene coating offers superior dry lubrication, low friction coefficient, and antibacterial properties, improving the surface conditions of dryness and adhesion. This brings significant convenience to users. Moreover, Parylene nano-coating can penetrate into the micro-porous structure on the surface of silicone products, forming a strong bond with the silicone surface. This ensures the integrity of the Parylene film even in frictional environments.

4. Application of Parylene in motors, fans, coils, and cores
In humid or harsh environments, components such as cores, rotors, stators, and motors made from silicon steel are prone to corrosion and rust. Therefore, solutions for waterproofing and corrosion protection must be considered for these parts prior to their application.
Parylene nano coatings utilize a unique Chemical Vapor Deposition (CVD) process, resulting in dense, pore-free coatings. This technology ensures outstanding moisture resistance, dust protection, corrosion resistance, and high-voltage tolerance for a wide range of products including cores, rotors, stators, and motors. Specifically, it achieves an IP68 dust-proof and waterproof rating, making it the preferred choice for the next generation of these products. It significantly extends the lifespan of these components.
