UV3102-M – UV/moisture cure Conformal Coating
UV3102-M is a one-component low-viscosity UV and moisture curing type conformal coating adhesive. It exhibits excellent adhesion to a variety of metal, ceramic, and glass-filled epoxy surfaces fulfilling the needs of the most demanding environmentally friendly applications in today’s PCB marketplace. It can be quickly cured to form a transparent adhesive layer under UV radiation. It is designed to protect printed circuit boards and related equipment from environmental erosion, so as to improve and extend their service life, to ensure safety and reliability.
Features and benefits
- Dual cure UV coating, one component
- Solvent-free, Halogen-free, Low odor
- Excellent moisture, heat and chemical resistance.
- Excellent adhesion
