Conformal Coatings: Acrylic - Acrylic Conformal Coatings are easy to apply. They dry to the touch at room temperature in minutes, have good electrically and physical properties and are fungus resistant. Acrylic conformal coatings have low or no exothermal during cure, which prevents damage to heat sensitive components, and are easy to repair. Polyurethane - Polyurethane conformal coatings provide excellent humidity and chemical resistance as well as very good electrical properties for extended periods of time. Most single component polyurethane conformal coatings require careful application procedures and close control of coating and curing environments.
Silicone - Silicone conformal coatings offer the highest flexibility, high moisture and fungus resistance, chemical resistance and excellent repair characteristics. Silicone conformal coatings offer excellent electrical properties and the thermal properties available. Silicone conformal coatings are available as 100% solids - heat-curing liquids, 100% solids - moisture curing liquids and a solvent borne moisture-curing material.
UV Curable - Many of the above chemistries are available in UV curable version which are solvent free products that cure in seconds when exposed to industrial UV/ visible light sources. Besides acrylics, polyurethanes and silicones, there are epoxy and acylated-urethane UV conformal coatings available.
