Product Introduction
Momentive SNAPSIL™ RTV6702 is a neutral-cure, one-component silicone adhesive sealant that cures at room temperature in the presence of atmospheric moisture. Supplied as a white paste, it can be applied to horizontal, vertical and overhead surfaces and offers a long work life for easy tooling. Once cured, SNAPSIL™ RTV6702 forms a tough, elastic silicone rubber with excellent electrical insulation, UV and weather resistance, and long-term performance from –60°C to 204°C for continuous use and up to 260°C for short periods.
Momentive SNAPSIL™ RTV6702 Features
- Neutral-cure, one-component system with no mixing required
- Primerless adhesion to many metals, glass and plastics
- Non-corrosive to most substrates
- Low-odor cure, releasing methyl alcohol and residual ammonia vapors
- Retains elastomeric properties from –60°C (–75°F) to 204°C (400°F) for long periods
- Withstands short-term exposure up to 260°C (500°F)
- Excellent electrical insulation properties
- Outstanding UV, chemical and weather resistance
- Paste consistency suitable for horizontal, vertical and overhead application
Momentive SNAPSIL™ RTV6702 Applications
- Bonding and sealing in confined spaces where room-temperature cure is required
- Electrical insulation and protective sealing of components and assemblies
- Joining metals, plastics, glass and ceramics in industrial equipment
- General-purpose silicone adhesive sealing up to 6 mm (1/4 in.) thickness
- Applications requiring non-corrosive, neutral-cure silicone with good environmental durability
