Momentive SNAPSIL™ RTV162 (White) – Electronic-Grade, Non-Corrosive Silicone Adhesive Sealant
SNAPSIL™ RTV162 is a white, one-component, ready-to-use, electronic-grade silicone adhesive sealant engineered specifically for sensitive electronic and electrical applications. It cures at room temperature upon exposure to atmospheric moisture, forming a tough, resilient silicone rubber that provides excellent protection without corroding copper, brass, or other acid-sensitive metals.
Unlike standard acetoxy-cure silicones, RTV162 utilises an alcohol-based (alkoxy) cure system, releasing non-corrosive alcohol vapours during cure. This results in a low-odour, non-pungent curing process, making it ideal for use in enclosed electronics assembly areas and applications where long-term reliability of metal components is critical.
RTV162 features a spreadable paste consistency, allowing it to be applied precisely to horizontal, vertical, and overhead surfaces in bead thicknesses up to 6 mm (¼ inch). It is not intended for use in sections thicker than 6 mm; for deeper potting, Momentive’s addition-cure or two-component systems are recommended.
- RTV160 - white flowable paste
- RTV162 - white paste
- RTV167 - grey, high-strength paste
Key Features
- Non-corrosive to copper, brass, and other sensitive metals – ideal for electronics
- Alcohol-based cure chemistry – low odor, safe for delicate components
- Electronic-grade purity – designed for printed circuit boards, semiconductors, and copper connections
- Paste consistency – stays in place without slumping during cure
- Room-temperature moisture cure – no mixing, heat, or primers required for most substrates
- Wide service temperature range: –60°C to 204°C (–75°F to 400°F) continuous; short-term up to 260°C (500°F)
