services of maintenance for preserving electronic components, printed circuit boards, final assemblies, and diakctric sheet The coating enhances protection of printed circuit board assemblies and electronic components subject to hostile environments and rugged conditions such as those found in marine,aerospace and military applications; The coating provides a secure envelope around a circuit board and its components and acts as a barrier against moisture, fungus, dust, corrosives and other environmental contaminants; Conformal coatings are offered in one and two-component systems in acrylic, polyurethane, silicone and UV coatings; Conformal coating can also enhance circuit reliability by eliminating detrimental conditions such as leakage from high impedance circuits and allowing closer circuit traces required with high component density
