Conformal coating
Description
An uninterrupted coating that assumes the exact form or shape of the object. Most conformal coatings are thin, nonconductive, dielectric layers were originally designed for the protection of electronics and electrical devices from moisture, contamination, chemicals, solvents, fungus, dust and corrosion. Because they are capable providing protection for a wide variety of substrates including metals, polymers, and semiconductors there use has expanded to include medical devices, automotive parts, consumer goods, and even works or art. Many types of polymers have been used for conformal coatings including, Acrylics, Epoxies, Silicones, Polyurethanes, Styrene and Parylene. One example, Parylene, is apllied via vapor deposited coating while more recent additions, such as Nanoproof and Vitroguard are available as solution-based coatings that can be dip or spray applied and requires little to no masking.
