antas-199 One-Component Structural Silicone Sealant

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 over 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 -50℃. It will not turn soft or deteriorated, and will keep good strength and flexibility at 150℃.
5. Compatibility with other neutral silicone sealants and other accessory facilities of structural glazing

1. Structural bonding of glass curtain wall.
2. Structural bonding of other curtain walls.
3. Bonding for industrial purpose or other buildings
