Coating or adhesive with added UV indicator, good flowability, fast tack free time, good flame resistance, MIL-A-46058 tested

Solventless RTV elastomeric conformal coatings such as DOWSIL™ 3-1944 RTV Coating require atmospheric moisture to cure needing no expensive ovens, and various viscosity version facilitates different application methods. This family of coatings is rapidly gaining popularity due to its environmentally friendly and solventless formulations, its rapid cure rates that can be dramatically accelerated by mild heat, and its cost-effectiveness.

These elastomers, when cured, offer the optimum stress relief for even the most delicate components and interconnections in a variety of service environments. This product line also features coatings manufactured for controlled volatility and many of these products are UL recognized. Conformal coatings are materials applied in thin layers (typically a few mils or microns) onto printed circuits or other substrates. They provide proven, cost-effective environmental and mechanical protection to significantly extend the life of the components and circuitry.
