Product Description

SMT-611 is a specified, premium performance weather sealing product specifically designed for general glazing and weather sealing in curtain wall and building facades  It is a one-part neutral-care architectural and engineering grade sealant. One of the rewarding properties of weather silicone sealant is that it extrudes in any weather conditions and cures at ambient temperature. This happens as it reacts with moisture in the air to form a durable and flexible silicone rubber seal.

Features

1.Excellent weatherability, virtually unaffected by sunlight, rain, snow, ozone  
2.Long-life reliability - cured sealant stays elastomeric from -50°C to 170°C without hardening, cracking or 
   becoming brittle under normal weather conditions  
3.Excellent unprimed adhesion to a wide variety of building materials

Typical Uses

1.General weather sealing of glass curtain walls, aluminum curtain walls.
2.Sealing the joints building façade, anodized aluminium, concrete enamelled and reflective glass, wood 
   glass-glazed surfaces, masonry, fluorocarbon coated aluminium, heat-strengthened glass etc.
3.Other construction structural glazing applications
