Reduce the risk of dendrite formation / electrochemical migration (ECM).

Minimize water absorption in humid environments

Improved Reliability

Impart low stress to solder joints, especially during thermal cycling

Very low levels of outgassing, critical for satellite and extreme remote sensing applications.

A low history of service needed in high-reliability apps, such as aerospace, defense, and medical devices.

Promote the durability of products, uptime, and employee and consumer safety.

Parylene has several types, each with unique properties. There is a Parylene for almost any application. Parylene types include:

Parylene F-VT-4 – Parylene F-VT-4 is highly crystalline. It has an excellent dielectric and very low friction coefficient. It is ideal for applications exposed to high temperatures.

Parylene N – Parylene N is an excellent dielectric. It is halogen-free and suitable for applications where sustainability is a priority.

Parylene C – Parylene C is the most used. It has the lowest permeability to moisture and gas, making it ideal for parts exposed to corrosive substances.

High submersion protection - IPX8+, also depends on device design.
Uniform, pinhole free coating.
High barrier protection against corrosive chemicals and gases. Low permeability to moisture. Best barrier when compared to the other Parylene types.
Optically transparent and can be used to coat optical elements.
Biostable, biocompatible, environmentally friendly — no VOCs, no solvents.
No initiators or catalysts in the polymerization process. The coating is pure and free from trace ionic impurities.
REACH, RoHS, PFOA/PFOS-free and CA Prop 65 compliant.
Room temperature formation makes the coatings effectively stress-free.
Low dielectric constant with good high frequency properties, good dielectric strength and high bulk and surface resistance.
High tensile strength.
No cure time.
Vibration resistant.
No pooling of coating in low areas.
Halogen free.
Free from bromine and chlorine halogens; contains fluorine.
Higher resistance to heat than Parylene C and N.
Highest temperature and UV resistant Parylene.
