RT-6500 is a single-component, neutral-cure silicone sealant that cures at room temperature through reaction with moisture in the air. It forms a flexible, long-lasting seal with excellent resistance to harsh weather, UV exposure, and temperature fluctuations. No primer is required for most substrates, making application fast and efficient.
Performance Highlights
1.Ready to use, no mixing required
2.Neutral curing - non-corrosive to metal and sensitive materials
3.Strong adhesion to glass, metal, stone, and more
4.Excellent resistance to weather, aging, and extreme temperatures
5.Maintains elasticity and seal integrity over time
6.Compatible with other RT silicone systems
Typical Uses
1.Glazing and sealing of windows and doors
2.Assembly of glass showcases and display units
3.Structural glass applications in commercial buildings
4.Joint sealing of glass, marble, aluminum, and other metals
5.General weatherproof sealing in both indoor and outdoor environments
