Silicone RTV Elastoplastic Conformal Coatings


Product description

DOW Silicones (formerly Dow Corning) delivers a wide variety of silicone-based polymers for diverse solutions in electric, electronic and energy applications. DOWSIL™ conformal coatings are materials applied in thin layers (typically a few mils or microns) onto printed circuits or other electronic substrates. They provide environmental and mechanical protection to significantly extend the life of components and circuitry. DOWSIL™ conformal coatings are traditionally applied by dipping, spraying, brushing or simple flow coating and increasingly by select coating, or robotic dispensing.

Silicone conformal coatings protect electronic printed circuit board from moisture and contaminants, preventing short circuits and corrosion of conductors and solder joints. They also minimise dendritic growth and the electromigration of metal between conductors. In addition, the use of conformal coatings protects circuits and components from abrasion and solvents. Stress relief is also provided, as is protection of the insulation resistance of the circuit board.

DOWSIL™ RTV elastoplastic conformal coatings have firm, dry surfaces for better handling and abrasion resistance after cure. They require atmospheric moisture to cure and their cure rates can be accelerated by elevated heat. They are supplied in solvent, with low-VOC versions available.
