Expanded steel structure fire retardant coating ASM02
Expanded steel structure fire retardant coating ASM02

Product introduction

Indoor inflatable steel structure fire retardant coating ASM01, is a thin paint film, excellent fire performance of water foam special coating, non-toxic, pollution-free, simple construction. Mainly coated on the surface of the steel structure, when the paint film meets fire quickly expand and foam, forming a uniform dense porous carbonized thermal insulation layer, to isolate air, delay the speed of heating steel components, avoid the rapid heating of the steel structure, so as to improve the steel structure of the refractory time.

Range of application


Widely used in (indoor) stations, industrial plants, stadiums, power equipment, high-rise buildings and other steel beams, purlin steel structure surface.

Construction procedures

1. Before painting, the surface of the steel structure should be treated and polished to thoroughly remove oil, rust and other sundries on the surface of the steel components.


2. Apply anti-rust primer. Choose alkyd and epoxy primer (water-based and solvent based). (the company can provide supporting products)


3 paint brush fire retardant coating, coating open cover before use, should be fully stirred evenly coating, such as coating too thick can be diluted with water, add water content recommendations do not exceed 10%, dilute to appropriate coating, do not flow can. This product is mainly applied by spraying, rolling coating and other methods, and shall be constructed several times. The thickness of the first time shall be controlled within 0.15mm, and the next time shall be constructed after the paint film surface dries (subject to the paint film not being used, usually at an interval of 4-8h). The thickness of the subsequent construction shall be controlled at about 0.2mm until the standard thickness required by the corresponding fire resistance grade is reached.


4 besmear brush topcoat, in order to improve the physical and chemical properties of fireproofing coating, it is recommended to wait for the paint film drying coating coating on the surface of a layer of fireproofing coating special topcoat.


Construction requirements


This product is water-based fireproof coating, the environmental temperature in the construction process should not be less than 5, the relative humidity should not be more than 80%, no matter in the construction process or after the construction should avoid rain, in order to prevent the film off.
