RT-6500 is a one-component, neutral-cure silicone sealant engineered for demanding construction and glazing applications. It cures at room temperature in the presence of atmospheric moisture, forming a flexible, weather-resistant seal that stands up to harsh environments and long-term exposure.
Highlights
User-Friendly Application - Ready to use, no mixing needed
Non-Corrosive Formula - Neutral curing system protects sensitive materials like metal and stone
Exceptional Adhesion - Bonds strongly to glass, aluminum, ceramic, concrete, and more
Long-Lasting Performance - Resists UV rays, extreme temperatures, moisture, and aging
Elastic & Durable - Accommodates movement without cracking or losing adhesion
Ideal for
Perimeter sealing of windows and doors
Curtain wall and glass façade installation
Sealing of aluminum, marble, and other cladding materials
Interior and exterior joints in residential and commercial buildings
General construction sealing in weather-exposed areas
