Product introduction Osmin NCB indoor ultra-thin fire retardant coating for steel structure has the core advantages of high fire resistance, convenient construction, environmental protection and safety, and is suitable for steel structure protection in complex indoor environment. It supports spraying, brush coating, roller coating and other processes. It is recommended to spray (air pressure is 0.4-0.6MPa, gun diameter is 1-3mm), and the thickness of single spraying is ≤ 0.5 mm. In practical application, the coating thickness should be adjusted according to the requirements of fire resistance grade, and the construction specifications should be strictly followed to ensure that the performance reaches the standard. Please refer to the product manual or manufacturer's test report for specific parameters. area of application Main scenes: Fire protection of indoor steel structures such as industrial workshops, gymnasiums, high-rise buildings, airports, stations and shopping malls. Applicable components: steel beam, steel column, grid, pipeline and petrochemical facilities support frame, etc. Description of construction technology Substrate treatment The surface of steel structure shall be thoroughly derusted and painted with antirust primer (such as epoxy red lead) to ensure no oil stain and dust. environmental control Construction temperature: 5-45℃; Humidity ≤85%, avoid rain, snow and dew. Layered coating Each coating thickness is ≤0.5mm, and the interval is 4-8 hours (it can be shortened to 3-5 hours with good ventilation). The total thickness needs to be controlled by measurement. save Storage period: 6 months Storage environment: dry and ventilated cool place, temperature 5-25℃, packaging barrel mouth upward.
