RT-6500 is a premium-grade, one-component silicone sealant that cures through atmospheric moisture at room temperature. It is specifically formulated for curtain walls, glazing, and general construction sealing where long-term durability, flexibility, and environmental resistance are required.
Key Advantages
Ready-to-use formulation - No mixing needed, easy to apply on-site
Neutral cure - Non-corrosive to sensitive substrates such as metals and natural stone
Superior adhesion - Bonds effectively to glass, aluminum, stone, and concrete
Outstanding durability - Resistant to UV, rain, temperature changes, and aging
Flexible and crack-resistant - Adapts to movement without compromising the seal
System compatible - Can be used with other RT silicone sealants in multi-product applications
Recommended Uses
Perimeter and glazing sealing for windows and doors
Weatherproofing of joints in curtain wall and facade systems
Bonding and sealing in architectural metal and stone frameworks
Indoor and outdoor sealing in both residential and commercial projects
