Dymax introduces Multi-Cure 9452-FC very low viscosity conformal coating

Dymax Corporation is proud to introduce Multi-Cure 9452-FC, a new conformal coating formulated with a revolutionary new technology as an alternative to thin, solvent-based conformal coatings. With a viscosity of only 20 cP, this unique 100% solids material provides a thin coating that is more environmentally friendly than solvent-based alternatives. The new multi -cure, light and heat-curable film coating provides good electrical insulation properties as well as humidity, thermal shock, and corrosion resistance.

Multi-Cure 9452-FC is designed for rapid conformal coating of printed circuit boards and other electronic assemblies. Typically, to achieve a very thin conformal coating, formulations are reduced using solvents. Until 9482-FC, light-cure coatings have been unsuccessful in providing the thinness and performance requirements needed.

Compatible with most types of spray equipment, 9452-FC fluoresces vivid blue when exposed to UV light (365 nm) for easy inspection of the coating coverage. It is also suitable for film coating or flow coating application. In addition, its secondary heat-cure feature allows the coating to cure with heat in applications where shadow areas exist. Another important feature of this very low viscosity material, is its ability to be cured under LED light in addition to broad spectrum light, giving users the option of curing systems for process optimization.

A recent Dymax white paper shows the coating's exceptional performance through reliability tests such as heat and humidity resistance (500 hours at 85°C / 85% relative humidity) and corrosion resistance (sulfur and salt spray resistance).
