Thermal Conductive RTV Silicone Sealant STTS

Technical Parameters:

  • Type: One-Component Room Temperature Vulcanizing Silicone Sealant
  • Color: Black/White/Gray Paste
  • Curing: Exposure to atmospheric moisture forms a silicone elastomer
  • Product Features:
    • Excellent adhesion to all kinds of materials
    • Non-corrosive to substrates
    • No fogging, low volatility
    • Stable and flexible from -40°C to +180°C

Typical Applications:

  • Bonding and Fixing
  • Thermal bonding of lamp components
  • Thermal bonding of high-power heating elements and radiators

Notice:

  • The sealant may experience slight yellowing during storage, but this will not affect its product properties.

Operating Instructions:

  1. Surface Clean: Ensure that the surface of the bonding substrate is free from dust, rust, and oil.
  2. Gluing: Squeeze the sealant onto the cleaned surface.
  3. Curing: Place the glued part in the air. After skin formation, curing continues inward from the surface. Under 25°C and 55% relative humidity conditions, it cures to a depth of 2 to 4mm in 24 hours. The curing depth gradually increases over time.
  4. Storage: The unused sealant should be immediately tightly sealed. Before reusing, remove any crust at the nozzle without affecting normal use. During storage, a small amount of solidification at the nozzle may occur, but it can be used normally after removal without affecting product properties.

Storage Conditions:

  • Store in a cool and dry place below 35°C.
  • Shelf Life: 6 months

Attentions:

  1. Keep away from children.
  2. It is recommended to use it in a well-ventilated area to reduce odors.
  3. If it accidentally comes into contact with the skin or eyes, wipe them clean immediately, then rinse with water and seek medical advice.
  4. For safety information, please refer to the Material Safety Data Sheet (MSDS).
