Product feature
  1. Neutral curing, no pollution or corrosion on metal, coated glass, concrete, marble and other building materials
  2. Excellent adhesion to most building materials
  3. Movement capacity:±35%
  4. Excellent weathering performance with over 15 years’ service life under general environment.
  5. Excellent performance within broad temperature range. The cured sealant will not change to be brittle, hardened or cracked at -50 ℃. It will not change to be soft and deteriorated, and will keep good strength and flexibility at 150 ℃.
  6. Compatibility with other neutral silicone sealants.
  7. Ideal material for jointing, sealing, bonding and moving joints.
Main purpose
  1. Bonding joints with high performance of weather ability for curtain wall.
  2. Sealing the gap of the construction wall, sandwich panel and wood wall.
  3. Other bonding and waterproof for general purpose.
