Antas-168 Two-Component Structural Silicone Sealant

Packaging : 180L+18L, 189L+18L
Antas-168 is a two component, neutral curing, silicone structural sealant, specifically designed for building curtain walls with hidden or semi-hidden frames. Long-term structural binding and sealing is formed by mixing and curing of the two components at designed ratio. It exhibits high modulus, high strength and high elasticity, providing excellent adhesion and weather resistance.

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. Excellent weathering performance with 25 years’ service life under general environment.
  4. Excellent performance within broad temperature range. The cured sealant will not turn brittle, hardened or cracked at -50º C. It will not turn soft or deteriorated, and will keep good strength and flexibility at 150º C.
Main purpose
  1. Structural bonding of glass curtain wall
  2. Structural bonding of other curtain wall
  3. Structural bonding for industrial purposes or other buildings
