With the continuous upgrading of global building fire safety standards in 2026, high-performance fire-retardant building materials have become mandatory configuration for public buildings, rail transit facilities and high-rise buildings. Daqin officially launched a new generation of halogen-free fire-retardant glass adhesive, which has passed national fire protection grade certification, filling the domestic market gap of high-performance flame-retardant special glass adhesive, and providing reliable safety sealing materials for high-risk fire protection scenarios.
Ordinary glass adhesives are flammable and will rapidly melt and burn when encountering open fire, releasing harmful smoke and losing sealing protection functions, which will accelerate the spread of fire in case of building fire. Most domestic fire-retardant glass adhesive products have problems such as low flame retardant grade, poor weather resistance and easy failure, which cannot meet the long-term safety requirements of high-standard fire protection projects. Daqin fire-retardant glass adhesive adopts new halogen-free flame retardant formula and high-temperature resistant molecular materials, abandoning traditional toxic flame retardant additives, achieving perfect balance between environmental protection and fire safety.
Test data shows that Daqin fire-retardant glass adhesive reaches the national B1-level fire retardant standard, with self-extinguishing function without open fire. It can form a dense carbonized protective layer at high temperatures above 1200℃, effectively isolating flame spread and smoke penetration, with a fire resistance limit of more than 3 hours. The product not only has excellent flame retardant performance, but also retains the weather resistance, anti-aging and bonding performance of high-end glass adhesives, and can be used for long-term outdoor building sealing without yellowing and aging.
At present, Daqin fire-retardant glass adhesive has been widely used in subway stations, airport terminals, hospital buildings, school facilities and high-rise commercial buildings, mainly used for fireproof sealing of glass curtain wall gaps, fire door and window glass gaps, and pipeline through-wall glass openings. Industry experts said that the launch of Daqin fire-retardant glass adhesive has standardized the domestic fire-retardant glass adhesive market, broken the technical barrier of high-safety fireproof glass sealing materials, and provided strong support for the upgrading of national building fire safety systems.
