High-Performance Flame-Retardant Engineering Sealant

Building silicone sealant is currently the most widely used waterproof and sealing material in interior and exterior decoration of buildings. Compared with ordinary building silicone sealants, flame - retardant silicone sealants have the characteristics of less smoke, non - toxicity during combustion, low heat of combustion, and slow flame spread rate. They are suitable for flame - retardant sealing in fire - resistant doors and windows, curtain wall projects, and various other construction projects.

The national standards specify the technical properties of GB 16776 - 2005 "Silicone Structural Sealants for Building" and GB 24267 - 2009 "Flame - Retardant Sealants for Building". However, in actual construction, due to complex and harsh working conditions, higher requirements are put forward for its flame - retardant and other properties. There is simply no V - 0 grade product on the market, or the products cannot meet the requirement of fluidity (leveling time of 5 minutes).

Our company has developed a high - performance flame - retardant engineering sealant, which has overcome the harsh construction requirements, and its performance far exceeds the national standard's top - grade products.
