UV3110-M – UV/moisture cure Conformal Coating
UV3110-M is a single-component, UV-curable, acrylated polyurethane conformal coating that possesses excellent chemical resistance, thermal shock resistance, 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 at ambient conditions. This coating fluoresces a bright blue when exposed to UV light (365nm) for easy inspection of coating coverage.
Features and benefits
- Secondary moisture cure
- Solvent-free, Halogen-free, Low odor
- Excellent moisture, heat and chemical resistance.
- Excellent adhesion
- Complies to the RoHS directive 2015/863/EU and 2011/65/EU.
