LY-04 fire retardant paint
LY-04 fire retardant paint has been inspected by "National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center" according to GB14907-2002 "General Technical Conditions for Steel Structure Fireproof Coatings". The physical and chemical properties are qualified, and the fire resistance limit can reach 2.5h. The coating has the advantages of strong adhesion, long durability, thin coating, high fire resistance, and easy construction. The coating quickly foams and expands when exposed to fire, and the coating forms a sponge-like thick fire insulation layer, which makes the steel structure difficult to bend and collapse when it encounters a fire, and prolongs the fire resistance time of the steel structure to achieve the fire prevention effect.
◆ Product composition < br Fireproof materials: ammonia polyphosphate, trihydrogen ammonia, pentaerythritol, chlorinated paraffin, titanium dioxide, etc .; binder: acrylic emulsion, amino resin, 100A solvent, etc .; asbestos-free, formaldehyde-free benzene And other volatile hazardous substances.
◆ Application range < br It can be used for fire protection of various steel members, spherical grids and other load-bearing steel structures in construction projects.
◆ Construction process · Steel structure surface should be completely derusted. Apply anti-rust paint twice. The surface is clean and free of oil.
· Stir the paint evenly before applying the brush. The thickness of the first coat should not exceed 0.5mm. After the coating is dry (about 6 hours)
· For the second pass of brushing, the thickness of the coating can be increased by an appropriate amount, two passes in 1 h, three passes in 1.5 h, four passes in 2 h, and five to six passes in 2.5 h.
When the coating feels thick during construction, it can be diluted by adding an appropriate amount of solvent. So as not to affect the adhesion and fire resistance of the coating.
· Construction operations should be carried out in a well-ventilated environment. Avoid rain during construction, and the construction environment should be above 0 ℃.
· The paint should be used up after it is opened. If it is not used clean, it must be sealed and kept intact.
◆ Packing, storage and transportation LY-04 fireproof paint is white, net weight is 25kg per barrel, storage temperature is 5-35 ° C, storage period is six months, storage and transportation prevent exposure to sunlight, rain, heavy pressure and upside down.
