Dual-Cure Light/Moisture-Cure Conformal Coating

Dual-Cure 9481-E is a solvent-free, light- and moisture-cure conformal coating specifically formulated to ensure complete cure in applications where shadowed areas on high-density circuit boards are a concern. Coating in shadowed areas cures over time with ambient moisture. This conformal coating fluoresces vivid blue when exposed to UV light (365 nm) for easy inspection of coating coverage. The low viscosity of 9481-E allows it to be dispensed easily with all of the current methods of dispensing.

This coating has been optimized for coating thicknesses between 25 mic [0.001 in] and 127 mic [0.005 in]. 9481-E excels in coating applications where chemical and abrasion resistance is critical.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
