Antas-168-25 Two-Component Structural Silicone Sealant

Packaging : 189L+19L, 180+18L

antas-168 is two-component, neutral curing silicone structural sealant. It is specially designed for structural glazing in Curtain Wall. It has excellent performance of structural glazing and weather-resistant, and can be used in broad temperature range with excellent structural sealing.

Product feature

1.Adjustable curing speed, fast solidification, suitable for continuous operation
2.Excellent weather durability, resistance to UV and hydrolysis
3.Wide range of temperature tolerance, with good elasticity within -50 to 150°C
4.Compatible with other neutrally cured silicone sealants and structural assembly systems

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
4.Secondary sealing of structural insulating glass

Standards compliant
