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 tack-free 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.

HumiSeal UV40 Dual Cure Acrylated Urethane Coating is a one-component, UV-curing polyurethane coating that offers high solids, flexibility, surface hardness, moisture and chemical resistance. It fluoresces under UV light to aid inspection and can be applied by spraying or brushing methods. 1 L Can.
