DOWSIL 3140 electronic component sealant Protective Coating for Circuit Boards
DOWSIL™ 3140 is a one-part, translucent, room-temperature vulcanizing (RTV) silicone coating/adhesive with excellent flowability and self-leveling properties. It is solvent-free, moisture-cured, and certified to UL 94 V-1, IPC-CC-830B, and military standards MIL-A-46146 and MIL-I-46058C. Ideal for electronics protection and circuit board encapsulation.
DOWSIL™ 3140 cures at room temperature (25°C) without ovens, reducing energy consumption and production costs. The cured elastomer offers excellent electrical insulation (dielectric strength 385 V/mil) and weather resistance (operating range -45°C to 200°C). Its UV indicator feature aids in manual/automated inspection of coating quality.
Flame Resistance: UL 94 V-1 certified (1.4 mm thickness) for fire-sensitive applications.
Fast Processing: Tack-free time 116 min (25°C), accelerable with mild heat (<60°C).
Adhesion: Bonds well to metals, ceramics, glass, and select plastics (peel strength 40 ppi).
Eco-Friendly: Solvent-free with 95.7% non-volatile content (NVC).
Electronics Protection: Corrosion-sensitive components, rigid/flexible PCB coating.
Encapsulation: Pin sealing, solder joint coverage, thin-section potting.
Industrial Uses: Sensor encapsulation, LED component protection (model-specific verification required).
