RT-8500 is a single-component, neutral-curing silicone sealant developed for structural glazing purposes. It cures quickly at room temperature when exposed to moisture in the air, forming a strong, elastic, and long-lasting seal. RT-8500 bonds effectively to a wide variety of common construction materials-no primer required-making it a dependable choice for structural sealing in both factory and on-site applications.
- One-part, neutral-cure system that simplifies application
- High modulus and excellent flexibility, ensuring strong structural performance
- Neutral cure-non-corrosive, odorless, and safe for a variety of materials
- Exceptional resistance to weathering, UV, high temperatures, and humidity
- Structural glazing: bonding and sealing of structural glass to metal frameworks, both in-factory and on-site
- Installation of curtain wall systems
- Structural glass projects in commercial and residential buildings
