Specification:
1, thick steel structure fire retardant coating does not contain asbestos and organic solvents, no harm to the human body.
2, thick steel structure fire retardant coating direct spraying and coating construction, drying and curing fast.
3, the coating light, strong bond, high strength, anti-corrosion performance is superior.
4, excellent fire resistance, weather resistance, outdoor use must do fire coating.
5. If necessary, the substrate shall not be treated with anti-corrosion treatment.
Instruction:
1. Before the coating of fire retardant coating, the surface derusting and anti-rust primer coating of steel members shall comply with the design requirements and the current relevant national specifications, shall thoroughly remove the dust, oil and other sundry on the surface of steel members.
2. Fire retardant coating should be applied before interior decoration and under the condition that it will not be damaged by subsequent works. During construction, the walls, doors and Windows, mechanical equipment and other components that do not need fire protection should be shielded and protected.
3. Brush the interface agent of Dongan steel structure once before spraying, and apply the coating method after the surface of the interface agent dries. Before painting, mix and stir evenly according to the ratio of powder: emulsion = 1:1, so that there is no caking thick fluid state.
4. The thin consistency shall be determined according to the coating method, which is convenient for construction, not flowing, and firmly bonded. For extra wide large steel should be added steel mesh, in order to prevent paint leakage or separation.6. The first time of spraying construction is not too thick, and the next time after it is dry, it is better not to flow until it reaches the standard thickness. The coating method of fireproof coating is basically the same as that of cement coating. Reference dosage: 20-22 kg / m²/ 25 mm
