Product Introduction
Momentive SNAPSIL™ RTV6708 is a neutral-cure, one-component silicone adhesive sealant that cures at room temperature when exposed to atmospheric moisture. Provided as a translucent paste, it can be easily applied to horizontal, vertical and overhead surfaces, and offers extended work time for proper placement and tooling. After curing, SNAPSIL™ RTV6708 forms a resilient silicone rubber with excellent dielectric properties, UV and weather resistance, and reliable performance across a wide operating temperature range.
Momentive SNAPSIL™ RTV6708 Features
- Neutral-cure, one-component adhesive sealant
- Primerless adhesion to many metals, glass, ceramics and rigid plastics
- Non-corrosive to most common substrates
- Low-odor cure mechanism
- Retains elastomeric properties from low to elevated service temperatures
- Excellent electrical insulation characteristics
- Strong resistance to UV exposure, chemicals and outdoor weathering
- Paste consistency suitable for multi-orientation application
Momentive SNAPSIL™ RTV6708 Applications
- Sealing and bonding of electronic and electrical assemblies
- Protective sealing in confined spaces where neutral cure is advantageous
- Bonding metals, glass, ceramics and selected plastics
- General industrial sealing requiring durable, weather-resistant silicone
- Applications needing reliable dielectric insulation under varying environmental conditions
