HumiSeal® UV40 is a single component, high solids, UV curable, acrylated polyurethane conformal coating that possesses excellent chemical resistance, surface hardness, flexibility and moisture resistance. The material is tackfree after exposure to UV light. A secondary moisture cure mechanism will cure unexposed areas of the coating within 2-3 days at ambient conditions. The coating fluoresces under UV light to allow for coating inspection and can be applied by selective coating equipment. HumiSeal® UV40 coating is recognized under UL File Number E105698, and is MIL-I-46058C qualified, and IPC-CC-830 and RoHS Directive 2011/65/EC compliant.
