RT-6500 is a one-part, neutral-curing silicone sealant formulated for long-term sealing performance in demanding architectural and industrial environments. It cures at room temperature by absorbing atmospheric moisture, producing a flexible, durable seal with outstanding resistance to weather, UV rays, and temperature cycling.
Performance Features
One-component system - easy application with no mixing
Neutral cure - safe for use on sensitive substrates including coated metals and natural stone
Excellent adhesion - suitable for glass, aluminum, steel, marble, and concrete
High weatherability - resistant to ozone, sunlight, rain, snow, and extreme temperatures
Maintains elasticity and bond integrity over time
Compatible with most silicone-based structural and weatherproofing systems
Primary Applications
Perimeter sealing of curtain wall systems
Weatherproofing joints in glass and aluminum assemblies
Installation of window frames, glass partitions, and showcase units
Façade and cladding joint sealing in commercial construction
General indoor and outdoor waterproof and weather-resistant applications
