Product Introduction
Momentive SNAPSIL™ TN3005 Adhesive Sealant is a one-component, low volatile siloxane silicone adhesive sealant that cures at room temperature upon exposure to atmospheric moisture. It offers primerless adhesion to many common substrates and cures to an elastic rubber available in clear, white or black. With fast tack-free time, low odor and a non-corrosive formulation, SNAPSIL™ TN3005 is well suited for electrical, electronic and general industrial sealing and bonding applications.
Momentive SNAPSIL™ TN3005 Adhesive Sealant Features
- One-component, room-temperature cure system
- Fast tack-free time for efficient assembly
- Low volatility (low levels of volatile siloxanes D3–D10)
- Non-corrosive to most metals
- Primerless adhesion to many substrates, including metals, glass and plastics
- Low-odor cure, releasing alcohol vapor during curing
- Flame retardant, UL94 HB recognized (File No. E56745)
- Good electrical insulation properties, including high volume resistivity
Momentive SNAPSIL™ TN3005 Adhesive Sealant Applications
- Insulating adhesive sealing and fixing of electrical and electronic parts
- Waterproof sealing for electrical, electronic and communication equipment
- General-purpose adhesion for metals, glass, plastics and other common substrates
- Applications requiring low-volatility silicone materials in sensitive electronic environments
- Assembly operations where non-corrosive, low-odor silicone is desired
