Antas-169 Structural Silicone Sealant

Model: antas-169

antas-169 is a one-part, neutral cure structural silicone sealant. It is designed and vigorously tested for structural bonding and sealing of glass curtain wall system with frameless design. It has high strength, excellent weatherproof ability and temperature durability. In a properly designed structurally glazed joint, the sealant is strong enough to support glass and other panel materials under high wind load.

Features

Neutral cure, no pollution or corrosion on metal, coated glass, concrete, marble and other building materials.
Excellent performance with over 25 years’ service life under general environment.
Excellent weatherability virtually unaffected by sunlight, rain, snow, ozone and temperature extremes of -40⁰C to 150⁰C.
Compatibility with other neutral silicone sealants.
High performance structural glazing and weather sealing from a single product.

Compliance Statement

The stated certifications and standards relate solely to the product as supplied by the manufacturer. Product performance is dependent on correct storage, handling, surface preparation, joint design, and installation in accordance with the manufacturer’s recommendations. Actual performance may vary depending on site conditions and application methods. For project-specific requirements, please refer to the latest Technical Data Sheet (TDS) or consult our technical team prior to application.

Substrate preparation

The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles.

Adhesion and cohesion test is recommended before application. The primer is usually not a required when applying antas-169 silicone structural sealant. But to enhance the bonding performance, the primer antas-201 primer will be a plus.
