Tunnel Fire Retardant Coating |
| Features | 1. High cohesive strength and good weather resistance. |
| 2. Water, moisture and frost resistance. | |
| 3. No poison and pollution, quick dry. | |
| 4.Excellent fire proof and flame retardant property. | |
| 5.Low construction cost, convenient installation, and reliable cost. | |
| Usage | It is sprayed or coated on the surfaces of the vaults or side walls of tunnels, subway or underground buildings, and is applied to the surfaces of concrete floors. The heat insulation layer is formed to prevent the temperature of the steel reinforced concrete from increasing quickly and lowering the strength, so it realizes the functions of fire proof, heat insulation and collapse prevention. |
