Testing of Novagard UV 800-260 demonstrates cure with extremely fast processing speeds and also incorporates a secondary, moisture cure chemistry for shadow areas of the coating. The 800-260 UV silicone product is ideally suited in printed circuit board applications of environments of high humidity, low or high temperature extremes or with water immersion. The 800-260 UV cured coating provides protection to the printed circuit board or control board in temperature extremes of -70° to +200° C, is V1 fire rated and maintains excellent dielectric properties. Utilization of a UV curable coating such as 800-260 is superior to heat-cured conformal coatings for printed circuit board applications with significantly higher processing speeds and lower energy requirements than conventional baked oven curing systems. Further, a nitrogen blanket is not necessary during UV curing of the silicone coating since Novagard UV 800-260 cure system is not inhibited by oxygen such as UV curable acrylic coatings.
