(Indoor) Thick Film Fire Retardant Coating

Thick-Fire-Resistant Paint~ Indoor Thick-Fire-Resistant Coating [Koguan Manufacturer - Manager Sun: 152_0825_6966] Sales in various regions including Sichuan, Chengdu, Yunnan, Chongqing, Guizhou, etc.; When heated, it foams to form a porous carbon layer (similar to thin coatings), but thick coatings rely more on non-expansive mechanisms, insulating heat through the low thermal conductivity of the coating itself (such as inorganic fibers, vermiculite, etc.).

Thick-fire-resistant coating is a special functional coating specifically used to enhance the fire resistance limit of building structures or equipment, primarily forming an insulating layer at high temperatures through physical and chemical mechanisms to delay the temperature rise of the substrate. Coating thickness: Typically applied at a thickness between 8mm~50mm, which is significantly higher than thin (<3mm) and ultra-thin (<1mm) fire-resistant coatings.

Application Scenarios
Building steel structures: Steel beams and columns in large venues and high-rise buildings (compliant with GB 14907 standard).

Industrial facilities: Petroleum pipelines, chemical equipment, cable trays in power stations.

Special structures: Tunnel fire protection (spray application), ship bulkheads.

Differences from Other Fire-Resistant Coatings

Key Construction Points

• Multi-layer application: Requires spraying or troweling in layers, with each layer dried before applying the next.

• Base treatment: Steel must be derusted and coated with anti-rust primer; concrete must be cleaned and moistened.

• Environmental requirements: Application at temperatures above 5°C, avoiding rainy or snowy conditions.
