HumiSeal® UV40HV is a high-solids, single-component, UV-curable acrylated polyurethane conformal coating. It offers excellent chemical resistance, surface hardness, flexibility, and moisture resistance. The coating is tack-free after UV exposure and features a secondary moisture cure for unexposed areas. It fluoresces under UV light for inspection and complies with RoHS Directive 2011/65/EU.
