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 fluorescence under UV light to allow for coating inspection and can be applied by selective coating equipment. UV-40 curable conformal coating is a single layer coating that is specifically designed for maximum level of protection of PCB’s. It is a thin film that is ensured on the topology of the circuit board and protects it from harsh chemical and mechanical environments.
