Fire Stop Silicone Sealant FNS911
One-component, neutral-curing silicone sealant, specifically designed for building fire stop requirements. Not only offers the basic sealing, adhesion, weather resistance, and high/low temperature resistance capability of sealants, but also provides excellent fire stop, flame retardant, and thermal insulation properties. This product is specifically suitable for fireproof sealing in buildings.The product has passed CZC fireproof sealant certification.
Features & Benefits
- Excellent fire resistance, reaching the highest level of A3 according to GB 23864.
- Excellent flame retardancy, reaching the highest level of FV-0 according to GB/T 2408.
- Good extrudability and thixotropy within the temperature range of 5℃ to 45℃.
- Excellent adhesion to building materials such as glass, metal, stone, and ceramics.
- Outstanding weather resistance and anti-aging performance, resistant to ultraviolet (UV) light, ozone, and water.
- Good high and low temperature resistance, maintaining excellent elasticity in the range of -50℃ to 150℃ after curing.
- Good compatibility with other neutral silicone sealants.
