Product Introduction of Momentive SNAPSIL RTV5818 Adhesive Sealant
Momentive SNAPSIL RTV5818 Adhesive Sealant is a translucent, neutral cure, one-component, ready-to-use silicone adhesive sealant. It cures into a tough, resilient silicone rubber when exposed to atmospheric moisture at room temperature. This fast-curing, paste-consistency product provides a quick initial adhesion build. Because of this rapid curing, it allows for the movement of sealed assemblies in a shorter period of time, effectively increasing productivity.
Key Features
- Provides primerless adhesion to many metals and plastics.
- Formulated to be non-corrosive to most substrates.
- Features a low odor during the curing process.
- Demonstrates good confined cure properties.
- Functions as a convenient one-component product with no mixing required.
- Retains its elastomeric properties at temperatures ranging from -60°C (-75°F) to 204°C (400°F) for long periods, and up to 260°C (500°F) for short periods.
- Cures efficiently at room temperature.
- Delivers excellent electrical insulation properties.
- Offers excellent resistance to UV, chemicals, and weathering.
Key Applications
- Ideal for general bonding and sealing applications in thicknesses up to 6mm (1/4 in.).
- Highly effective for joining metals and plastics together.
- Used extensively for electrical insulation purposes.
