Snapsil RTV122 is a one-component, ready-to-use adhesive sealant. It cures to a tough, resilient silicone rubber upon exposure to atmospheric moisture at room temperature. This formulation provides reliable bonding for diverse materials. It ensures robust sealing in demanding industrial environments. Engineers trust its consistent performance.
General Information of Snapsil RTV122
This advanced silicone adhesive sealant operates as a single-component system. It initiates cure through atmospheric moisture at ambient temperatures. The curing process releases alcohol and residual ammonia. This mechanism forms a durable, elastomeric bond. Furthermore, Snapsil RTV122 exhibits primerless adhesion to many common industrial substrates. These include various metals and plastics. It is specifically non-corrosive to aluminum and steel, meeting MIL-A-46146A standards. However, users should note potential discoloration with sensitive metals like copper or brass.
The material presents as a thixotropic paste, facilitating precise application. Snapsil RTV122 maintains its elastomeric properties across an extensive temperature range. This spans from -60ºC (-75ºF) to 204ºC (400ºF) for prolonged periods. It also withstands short exposures up to 260ºC (500ºF). Consequently, it offers exceptional weatherability, ozone, and chemical resistance. These attributes ensure long-term reliability in harsh conditions.
Key Features & Technical Benefits
- Primerless Adhesion: Achieves strong bonds to many metals and plastics without a primer. This simplifies application processes and reduces material costs.
- Non-Corrosive Formulation: Does not corrode aluminum and steel, adhering to MIL-A-46146A standards. This protects sensitive metal components from degradation.
- Excellent Electrical Insulation: Provides superior dielectric strength and volume resistivity. This safeguards electrical components and ensures operational integrity.
- Wide Temperature Stability: Retains elastomeric properties from -60ºC to 204ºC for extended periods. This ensures reliable performance in extreme thermal environments.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Sealing vertical joints in various assemblies.
- Bonding dissimilar materials, such as metal to plastic and glass to aluminum.
- Electrical insulation of wires and terminals.
