Thermal Potting RTV Silicone Sealant SSTT

Technical Parameters:

  • Type: Two-component RTV Silicone Adhesive
  • Curing Type: Dealcoholized, 1 to 1 condensed type curing
  • Color: White/Black Paste
  • Curing: Fast curing at room temperature, curing to a tough, flexible rubber
  • Product Features:
    • Excellent adhesion to various substrates
    • Non-corrosive to substrates
    • Excellent dielectric properties
    • Excellent weather fastness
    • Complies with EU ROHS
    • Stable and flexible from -40°C to +180°C

Typical Applications:

  • Bonding various home appliance panels, brackets, pendants, such as microwave oven induction cooker brackets bonding
  • Mica plate and collar bonding
  • Solar backplane and glass bonding


  • In the process of storage, the sealant may experience a small amount of solidification or oil penetration at the nozzle. It can be used normally after removal without affecting the product properties. For double-tube packaging, squeeze a small amount of sealant at the same time before components A and B to eliminate air bubbles in the head, and then connect the mixing tube.

Operating Instructions:

  1. Clean Surface: Ensure the surface of the bonding substrate is free from dust, rust, and oil.
  2. Mixture Ratio: Mix according to the weight ratio of 1 to 1. If you need to change the ratio, it should be applied after testing.
  3. Gluing: Squeeze the sealant onto the cleaned surface.
  4. Curing: Place the glued part in the air for natural curing. The higher the temperature of the environment, the shorter the working and curing time. Do not heat cure, as it may introduce air bubbles inside the sealant, affecting the bonding and sealing effect.
  5. Storage: The unused sealant should be immediately tightly sealed. Before using again, a small amount of solidification at the nozzle may occur, but it can be used normally after removal without affecting the product properties.

Storage Conditions:

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


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

Packaging Specifications:

  • 2600ml / piece, 4 pieces / Carton
