RT-6500 is a one-part, neutral-curing silicone sealant designed for durable and weather-resistant bonding in building and glazing projects. It cures at room temperature by absorbing moisture from the air, forming a long-lasting, flexible seal without damaging sensitive substrates.
Product Advantages
Neutral Cure System - Non-corrosive to metals and compatible with natural stone
Excellent Durability - Resists UV, moisture, temperature changes, and aging
Strong Adhesion - Bonds securely to glass, aluminum, concrete, ceramic, and more
Flexible Seal - Accommodates joint movement without cracking or shrinking
No Primer Needed - Easy to apply directly on most clean, dry surfaces
Application Areas
Window and door frame sealing
Glass curtain wall joints and facade systems
Exterior and interior sealing for stone, metal, and concrete structures
