Antas-176 Fireproof Silicone Sealant

Packaging : 300mL

antas-176 is specially designed for flame-resistant and joint sealing on horizontal and vertical planes of buildings, pipes and gaps. antas fire stop sealant it has excellent performance of flame resistance whichsave people more time from fire hazard.
Product feature
  1. Outstanding fire-resistant property; up to FV-0 of GB/T2408-1996
  2. Good extrusion and thixotropy between 4℃~40℃. Easy to use;
  3. Neutral curing, non-corrosive to metal, coated glass, concrete, marble, granite etc;
  4. Excellent weathering and aging performance without unpleasant odor during curing.
  5. Excellent resistance to UV, ozone and water;
  6. Excellent resistance to low and high temperature. The cured always keeps good elasticity without fragility, rigidification or crack at -30 ℃ , and no softening, degradation at 90℃.
  7. Excellent adhesion to most building materials;
  8. Good compatibility with other neutral silicone sealants.
Main purpose
  1. Joint sealing and fire-proofing for all kinds of building with fireproof requirements
