HumiSeal® 1C63 is a UV/RTV curing, oxime-type cure silicone conformal coating which provides excellent moisture and environmental protection for printed circuit assemblies. HumiSeal® 1C63 is a non-corrosive, single component coating which will cure upon exposure to either a UV light source or atmospheric moisture at ambient or elevated temperatures. The material is tack-free after exposure to UV light. A secondary moisture cure will cure unexposed areas of the coating within 24 hours at ambient temperature, 50% relative humidity. HumiSeal® 1C63 is self-leveling, with excellent weathering resistance. HumiSeal® 1C63 is recognized under UL File Number E105698 and RoHS Directive 2011/65/EC compliant.
