Translucent RTV Silicone Sealant SOTO

Technical Parameters:

  • Type: One-Component Room Temperature Vulcanizing Silicone Sealant
  • Color: White/Black Paste
  • Curing: Cures on exposure to atmospheric moisture to form a silicone elastomer

Product Features:

  • Moisture Curing, No corrosion to most substrates
  • Excellent adhesion to various substrates
  • Excellent dielectric properties and weather resistance
  • Stable and flexible from -40°C to +180°C
  • Complies with RoHS

Typical Applications:

  • PCB board component fixing
  • Bonding and fixing
  • Moisture-proof seal


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

Operating Instructions:

  1. Clean Surface: Clean the dust, rust, and oil from the surface of the bonding substrate.
  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, the sealant will cure 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 tightened and 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 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 accidentally touches 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).
