UV3102-M is a one-component low-viscosity UV and moisture-curing – dual cure conformal coating adhesive. It can be quickly cured to form a transparent adhesive layer under UV radiation. This product is designed to protect printed circuit boards and related equipment from environmental erosion, to improve and extend their service life. UV3102-M fluoresces a bright blue when exposed to UV light (365nm) for easy inspection of coating coverage.
FEATURES:
- Dual cure UV coating, one component
- 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.
