Product Description

RT-8500 is a one-component, neutral cure, fast-curing silicone sealant specifically designed for structural glazing applications. It cures at room temperature through reaction with atmospheric moisture to form a permanently flexible, durable silicone rubber. This professional-grade sealant offers excellent adhesion to a wide variety of substrates without the need for a primer.

Feature

- Single-component, neutral cure, room temperature curing system.
- High modulus and excellent flexibility for superior structural performance.
- Outstanding adhesion to a wide range of curtain wall materials, including coated, enameled, and reflective glass, as well  as anodized, oxidized, or coated aluminum and stainless steel.
- Excellent mechanical strength with a joint movement capability of ±12.5%.
- Neutral cure-non-corrosive and non-toxic.
- Maintains stability and performance across a broad temperature range from -50°C to +150°C.
- Exceptional weather resistance, including high tolerance to UV rays, heat, and humidity.

Application

- Structural glazing, including bonding and sealing of structural glass and metal components either in the factory or on-site.
- Curtain wall assembly.
- General structural glass installations in construction projects.
