Antas-176 Fireproof Silicone Sealant

Outstanding fire-resistant property; up to FV-0 of GB/T2408-1996
Good extrusion and thixotropy between 4℃~40℃. Easy to use;
Neutral curing, non-corrosive to metal, coated glass, concrete, marble, granite etc;
Excellent weathering and aging performance without unpleasant odor during curing.
Excellent resistance to UV, ozone and water;
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℃.
Excellent adhesion to most building materials;
Good compatibility with other neutral silicone sealants.

Joint sealing and fire-proofing for all kinds of building with fireproof requirements
