RT-8500 is a ready-to-use, one-component, neutral-cure, fast-curing silicone sealant designed for structural applications. It cures at room temperature by reacting with atmospheric moisture to form a permanently flexible and durable seal. RT-8500 offers excellent adhesion to a wide range of substrates without the need for a primer, making it a professional-grade solution for demanding structural glazing projects.
- One-component, neutral cure, room temperature curing system
- High flexibility and high modulus with outstanding structural performance
- Excellent adhesion to a wide variety of curtain wall materials, including coated, enameled, and reflective glass, as well as anodized, oxidized, or coated aluminum and stainless steel
- Superior mechanical properties with ±12.5% joint movement capability
- Neutral cure formula: non-corrosive and non-toxic
- Wide temperature stability from -50°C to +150°C
- Exceptional weather resistance, including high resistance to UV rays, heat, and humidity
- Structural glazing: used for bonding and sealing joints between structural glass and metal, either in factory settings or on construction sites
- Curtain wall assembly
- Installation of structural glass elements in construction projects
