NCB Interior fire retardant coating for ultra-thin steel structure

Product introduction

Indoor ultra-thin steel structure fireproof coating, is a kind of water-based expansion special coating with thin paint film and excellent fireproof performance, and non-toxic, pollution-free, simple construction. Mainly painted on the surface of the steel structure, when the paint film after the fire rapidly expanded foam, formation of uniform dense porous carbonization insulation layer, to isolate air, delay the heating rate of steel components, to avoid the steel structure quickly heating, so as to improve the fire resistance time of the steel structure. (osmin is a subsidiary of obechi)

Range of application

It is widely applied to steel beam and purlin steel structure surface of railway station, industrial plant, stadium, electric power equipment, high-rise building, etc.

Product features

Thin film, excellent fire performance water-based expansion of special coatings, and non-toxic, pollution-free, simple construction

Construction procedures

Steel structure surface treatment - paint brush rust primer - paint brush fireproof paint - paint finish

1. Before painting, the surface of the steel structure should be processed and polished to completely remove oil stains, rust and other sundries on the surface of the steel members.

2. Apply anti-rust primer, choose alkyd, epoxy (water based, solvent based). (our company can provide supporting products)

3 coating brush fireproof coating, coating open cover before use, should be fully stirred evenly, such as paint too thick can be appropriate amount of water dilution, add water recommendations not more than 10%, dilution to appropriate coating, not flowing can be. This product is mainly used for spraying and rolling coating, which needs to be carried out several times. The thickness of the first time shall be controlled within 0.15mm, and the next time shall be carried out after the paint film surface is dry (the paint film shall not be stained with hands, and the interval is usually 4-8h). The subsequent thickness of each time shall be controlled around 0.2mm until the standard thickness required for corresponding fire resistance grade is reached.

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