Product Introduction
Momentive SNAPSIL™ TN3705 Silicone Adhesive Sealant is a one-component, low volatile siloxane silicone that cures at room temperature when exposed to atmospheric moisture. Provided as a flowable material in clear, white or black, it forms an elastic, non-corrosive rubber with good adhesion to many substrates without a primer. With quick tack-free time, low odor, flame retardancy and stable electrical properties, SNAPSIL™ TN3705 is well suited for a broad range of electrical, electronic and general sealing applications.
Momentive SNAPSIL™ TN3705 Silicone Adhesive Sealant Features
- One-component, room-temperature curing silicone sealant
- Fast tack-free time to support higher throughput
- Low volatile siloxane content (D4–D10)
- Non-corrosive to most metals and electronic materials
- Primerless adhesion to many common substrates
- Low-odor cure with alcohol vapor release
- Flame retardant, UL94 HB (File No. E56745)
- Good electrical insulation, including high volume resistivity and dielectric strength
- Flowable consistency for easy application and coverage
Momentive SNAPSIL™ TN3705 Silicone Adhesive Sealant Applications
- Insulating adhesive sealing and fixing of electrical and electronic components
- Waterproof sealing of electrical, electronic and communication equipment
- General-purpose adhesive for metals, glass and engineering plastics
- Applications requiring low-volatility, non-corrosive silicone materials
- Electronic assemblies needing flame-retardant sealing solutions
