Momentive SNAPSIL™ RTV167 (Grey) – High-Strength, Electronic-Grade, Non-Corrosive Silicone Adhesive Sealant
SNAPSIL™ RTV167 is a grey, one-component, ready-to-use, electronic-grade silicone adhesive sealant engineered for applications requiring high mechanical strength and non-corrosive protection of sensitive metals. It cures at room temperature upon exposure to atmospheric moisture, forming a tough, resilient silicone rubber that delivers exceptional adhesion and long-term environmental resistance—without corroding copper, brass, or other acid-sensitive conductors.
Unlike standard acetoxy-cure silicones, RTV167 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 electronics assembly, aerospace, automotive, and appliance applications where reliability, safety, and compatibility with metal components are critical.
RTV167 features a spreadable paste consistency, allowing precise application 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.

Key Features
- Non-corrosive to copper, brass, and silver – safe for sensitive electronic assemblies
- High tensile strength (800 psi) and 600% elongation – ideal for structural bonding in electronics
- Alcohol-based cure chemistry – low odour, no acetic acid by-products
- Electronic-grade purity – designed for printed circuit boards, semiconductors, and high-reliability connectors
- 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)
- Excellent electrical insulation, moisture resistance, and UV/ozone stability
Typical Applications
- High-strength bonding and sealing of electronic components on PCBs
- Protection of copper traces, wire bonds, and power modules in automotive and aerospace systems
- Encapsulation of sensors, relays, and control units requiring mechanical durability and corrosion-free performance
- Applications where disassembly may be needed, but long-term environmental sealing is required
