Avoid Misconceptions and Choose the Right Fire Retardant Coating: Different spaces and materials have varying performance requirements for fire retardant coatings. Therefore, when selecting paint, consult experienced store sales staff. Using the appropriate fire retardant coating in suitable locations ensures effective fire prevention.

Misconception 1

Apply fire-resistant wood coating to steel structures

Due to the fact that both wood-structured and steel-structured fire-resistant coatings are indistinguishable to the naked eye, consumers must be aware of the detailed properties of fire-resistant coatings when making their selections. If steel structures are coated with wood-structured fire-resistant coatings, the adhesion will significantly decrease, and they are prone to peeling off, which cannot ensure fire safety.

Misconception 2

Unspecified solvent-based and water-based fire retardant coatings

There are two types of fire-resistant coatings for steel structures: solvent-based fire-resistant coatings and water-based fire-resistant coatings. In terms of adhesion, solvent-based coatings have greater strength than water-based ones. Therefore, solvent-based fire-resistant coatings should be used for outdoor steel structures, while indoor steel structures can utilize either solvent-based or water-based coatings.

Some domestic manufacturers produce fire-retardant coatings that release toxic gases when exposed to fire. If such coatings are used on fire-resistant electrical products, toxic gases will be emitted upon a fire. For instance, the obsolete G60 chlorinated polyvinyl chloride fire-retardant coating, which releases toxic chlorine gas when ignited, should not be selected.

The quality of fire-retardant coating application affects the fire resistance of the material, so attention must be given to the coating quality of fire-retardant paints. While the application methods for different fire-retardant coatings may vary slightly, the basic construction points are the same.
