FP-ST ultra-thin steel structure fireproof coating is mainly used for the fire protection of some large objects that will be destructed by the fire, such as industrial and civil building's indoor steel structure. It is especially applicable to protect bare steel structure of the venues and industrial factories. It can effectively improve the refractory ability of the steel structure, and have good fire-resistance adornment effect at the same time. It is suitable for coating of cable tray and instrument pipe, etc.
Product advantages:
No benzene class and asbestos materials;
After high-temperature foaming, this product will not produces non-toxic gas, which is harmless to human beings;
When the film dries, the coating will be tasteless, non-toxic, hard, resistant to knock, and vibration resistance.
Installation Instructions:
Steel structure surface treatment: Before construction, clean dust and rust spots on the surface, and apply anti-rust paint compatible with the fireproof coating.
Anti-rust primer application: Apply 1 coat of anti-rust primer, cure indoors for over 24 hours before applying the fireproof coating.
Fireproof coating application: Use brushing, rolling or spraying. First, stir the coating thoroughly; the first coat thickness is 0.1-0.15mm (to enhance adhesion and prevent peeling/cracking), and subsequent coats are 0.2-0.3mm thick.
Interval & environment: Allow 8-18 hours between coats. Suitable conditions: 15-25℃, 40-60% relative humidity, well-ventilated site, wind speed ≤5m/s. Prohibit construction when relative humidity ≥85%, or in stuffy air, low air pressure, or when the steel surface is damp/dewy.
