Parylene is a transparent, colorless polyester protective material suitable for vacuum deposition at room temperature. While vacuum deposition pressure is typically below 10⁻⁵ Torr, the Parylene process operates at around 0.1 Torr. Coating thickness can be precisely controlled between 1 and 100 microns. This coating was patented in the US in the early 1960s and was first applied to US military printed circuit boards, aerospace, and microelectronic components for underwater launch systems. In 1972, it was incorporated into the US Military Standard: MIL-I-46058C.

Parylene utilizes a unique Chemical Vapor Deposition (CVD) process, where active small molecules grow into a fully conformal polymer film on the substrate surface. It can coat surfaces of any shape, including sharp edges, cracks, and internal surfaces.

This room-temperature deposited thin film (0.1-100 microns) is uniform, dense, pinhole-free, transparent, stress-free, additive-free, and non-damaging to workpieces. With its excellent electrical insulation and protective properties, it stands as one of the most effective contemporary coatings against moisture, mold, corrosion, and salt spray.

Product Application

PCB Coating：Parylene's vapor deposition enhances circuit integrity and eliminates moisture, metal ions, and pollutants without altering component functions like resistance. It effectively protects sensitive electronic elements.
Medical Devices：Providing an inert, insulating, and pinhole-free barrier, Parylene is biocompatible (FDA compliant) and ideal for implants (stents, pacemakers), surgical tools, and disposable medical supplies.
Heritage Preservation：A revolutionary material for archaeology, Parylene reinforces fragile artifacts, fire-damaged paper, and books without changing their appearance, significantly extending their lifespan.
LED Outdoor Lighting：It offers superior protection against water, moisture, aging, corrosion, and UV rays, excelling in harsh conditions like thermal shock and saltwater immersion where other coatings fail.
Sensor Protection：Highly resistant to acids, alkalis, and solvents, Parylene protects sensors in automotive and biomedical fields. Its ultra-thin layer blocks harsh environments without affecting the sensor's size, look, or flexibility.
Magnetic Materials：Parylene insulates magnetic windings, prevents friction, and improves dielectric strength. It overcomes the wear and chemical resistance limitations of traditional epoxy coatings.
Silicone Rubber：Coating silicone products (like keypads) enhances print durability and chemical resistance. It is also widely used to lubricate rubber seals and protect them from acids and moisture.
Other Applications：Parylene can be fabricated into precision thin films for specialized uses, such as sealing gaskets in missile launch tubes and coated generator films.
