Thermal RTV Silicone Sealant Material STTF

Technical Parameters:

  • Type: One-Component Room Temperature Vulcanizing Silicone Sealant
  • Color: White Paste
  • Curing: Cures on exposure to atmospheric moisture to form a silicone elastomer
  • Product Features:
    • No fogging, low volatility
    • High bonding strength to all kinds of materials
    • Non-corrosive to substrates
    • Stable and flexible from -40°C to +180°C

Typical Applications:

  • Bonding and Fixing
  • Heat conduction bonding of lamp components
  • Heat conduction bonding of high-power heating element and radiator

Notice:

  • The sealant may slightly yellow during storage, which will not affect product properties

Operating Instructions:

  1. Clean Surface: Ensure 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. With prolonged time, the curing depth gradually increases.
  4. Storage: The unused sealant should be immediately tightly sealed. Before using it again, remove any crust at the nozzle mouth without affecting normal use. During storage, a small amount of solidification may occur at the nozzle, 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

Packaging Specifications:

  • 100ml / piece, 100 pieces / Carton.
  • 300ml / piece, 24 pieces / Carton.
  • 2600ml / piece, 4 pieces / Carton.

Attention:

  1. Keep away from children.
  2. It is recommended to use it in a well-ventilated area to reduce odor.
  3. If 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).
