Product introduction

Osmin outdoor water-based intumescent fire retardant coating has passed the national fixed fire extinguishing system and fire-resistant component quality supervision and inspection center, and has been tested according to the standard GB14907-2018 "General technical conditions for fire retardant coatings for steel structures", and its physical and chemical properties are qualified. The intumescent fire retardant coating for steel structure developed and produced by our company has the advantages of thin coating (the maximum construction thickness is 3.2mm), high expansion coefficient of coating, good compactness of carbon layer, high strength, excellent fire retardant effect, environmental protection and innocuity, and simple construction. Good adhesion and long durability. The coating expands rapidly in case of fire, forming a sponge-like thick fire-proof and heat-insulating layer, which makes the steel structure difficult to bend and collapse in case of fire, and prolongs the fire-resistant time of the steel structure to 2 hours, thus achieving the fire-proof effect.

area of application

Outdoor intumescent fire retardant coatings for steel structures are used for fire protection of outdoor steel structures such as exhibition halls, industrial workshops, stadiums, airport terminals, office buildings, shopping malls, civil buildings and airport terminals.

Description of construction technology

1, grassroots processing

Remove rust, attachments, dust and oil stains from the steel surface.

2. Paint antirust primer

According to the design requirements (anti-rust paint type, construction thickness), apply anti-rust primer.

3, painting fire retardant coating

Before painting fire retardant coatings, rust, attachments, dust and oil stains on the base surface should be removed. In case of large-scale rust return, antirust paint should be applied to prevent rust return in the construction of fire retardant coatings.

After the fire retardant coating is opened, it should be said that the coating should be stirred evenly, and then the viscosity of the fire retardant coating should be adjusted according to the construction method. The construction method shall be selected according to the site requirements and site conditions.

matters need attention

The intumescent fire retardant coating shall be protected from rain during and after construction. Remarks: After the construction of outdoor intumescent fire retardant coating for steel structure, top coat must be made.
