Specialty Coating Systems (SCS, Indianapolis, IN), a Cookson Electronics Company, has introduced Parylene HTSM conformal coating for the automotive, industrial, military and electronics industries. The coating provides protection to parts and electronic components that operate in harsh environments where temperature, chemical, electrical, moisture and UV stability challenges exist.

The coating meets the specifications of component manufacturers with long-term thermal stability up to 350ºC, with intermittent exposures up to 450ºC. It also offers UV stability, crevice penetration, a low dielectric constant and a low dissipation factor.

It is applied at room temperature via a vapor deposition polymerization process, resulting in a pinhole-free, protective coating. The coating is inert, solvent and catalyst free, does not out-gas, and in ultra-thin coatings results in little dimensional or mass change to the coated component.
