Fire resistance of light steel workshop Fire retardant coating Price of fireproof paint
Fire resistance and fire prevention of light steel workshop coating Fire retardant paint quotation, fire retardant coating fire retardant paint for light steel plant It can be divided into water and oil (solvent). When exposed to fire, the foaming component in the coating film of the product is decomposed by heat, and the expansion and thickening produce a dense and uniform fireproof and thermal insulation protective layer, which can generate decomposition endothermic reaction, prevent heat transfer, delay the temperature rise of the steel structure, and greatly improve the fire resistance time of the steel structure. The coating is a kind of fireproof coating for steel structure with good expansion and thermal insulation performance under fire and good decorative performance. In the fire-resistant and fireproof coating of the plant, Waterborne paint It can be made with clean water diluent Without any corrosion protection Primer Chemical reaction; The oily coating needs to be diluted with diluent. Compared with the water-based fireproof coating, it is more convenient for winter construction and can be modulated into various colors according to the needs of users. The fire-resistant and fireproof coating for factory buildings has the advantages of ultra-thin and flat coating, strong adhesion, good fire-resistant performance, good decoration, convenient construction, etc. It can be widely used in industrial and civil steel structure workshops, gymnasiums, exhibition halls and other steel structure buildings for fire protection.

construction technology
1. The pre coated steel structure surface shall be clean, dry and pure. If there is grease on the surface, clean it with solvent. Before coating this product, the surface of steel structure components needs qualified anti-corrosion treatment, and the steel structure fireproof coating can be applied after the anti-corrosion primer is dry.
2. This product is a single component coating, and no other components need to be added. Before construction, it should be stirred evenly with a mixer to ensure the overall uniformity of the coating.
3. In general, this product does not need to be diluted with diluent. If the viscosity of the paint system is too high, it can be diluted with water not exceeding 5% of the total weight and stirred evenly.
4. Construction method: brush coating, roller coating and spraying are recommended for this product. It is recommended that the construction amount for each pass be 200-300g/m2 or 100-300 μ m. The next coating can be carried out after the previous coating is dry; The thickness of each coat can be increased appropriately from the second coat, but it is better not to flow. 5-10 coats are required to reach the required coating thickness.
