antas-199 One-Component Structural Silicone Sealant

Packaging : 300mL, 500mL, 590mL

antas-199 is one-component, neutral curing silicone structural sealant. It is specially designed for structural glazing in glasscurtain wall. It has high performance of structural bonding and excellent weather ability. It can be widely used in broad temperature range, and is cured by the moisture in air to form an elastomeric rubber ensuring tight structural bond.
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 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
Main purpose
1. Structural bonding of glass curtain wall.
2. Structural bonding of other curtain walls.
3. Bonding for industrial purpose or other buildings
