Outdoor Steel Structure Fireproof Coating
Description:
This ZB60-1 outdoor steel structure fireproof coating (exterior steel fireproofing painting)is widely used in fireproof protection of inside and outside steel structures in petrochemical enterprises, roads, railways, and tunnels. It is solvent-based, intumescent mastic fire protective coating for structural steel, concrete, and other construction materials, for both interior and exterior applications. The exterior steel fireproofing painting is ideal for use in a wide variety of commercial, institutional and industrial environments where conventional fireproofing is not sufficiently rugged, lightweight or appropriate as a finish.
Processing Flow of Outdoor Steel Structure Fireproof Coating (Exterior Steel Fireproofing Painting):
1. The steel structure need to be derusting for the surface and anti-corrosive precoating primer, so that the surface of base materials is neat, dry, and oil free, which is important for the fireproof coating.
2. The uniform surface priming with 1-2mm thick is another important process before coating the thick film outdoor steel structure fireproof paint.
3. Then the ZB60-1 paint, water and special adhesive have to be mixed in the proportion of 3:2:1, while the water quantity can be slightly varied in the mixture so as to accommodate to spray finishing or smearing. This mixer is then prepared for painting.
4. This steel fireproof coating is powdery mixture, the ZB60-1 paint and water is approximately 1:0.8. In the meanwhile, it is better for instant usage, with viscous coating until, so use up the prepared paint as soon as possible.
5. Generally speaking, the first time painting should be 6-10mm thick, while the time interval from the next coating depends on environmental temperature, with 24h interval at 20℃.
