Misunderstandings in choosing fire retardant coatings

Avoid misunderstandings and choose suitable fire retardant coatings: Different spaces have different performance requirements for fire retardant coatings without materials. Therefore, when purchasing coatings, you can ask an experienced store salesman to find out if suitable for fire retardant coatings. In order to achieve the best fire protection effect, use suitable fire retardant coatings in suitable places.

Myth 1

Use fire retardant coatings for wood structures on steel structures. Since the fire retardant coatings for wood structures and steel structures cannot be recognized by the naked eye, consumers must understand the characteristics of fire retardant coatings when purchasing. Detailed properties. If the steel structure uses the fireproof coating of the wood structure, its adhesion is greatly reduced, and it is easy to fall off, which cannot guarantee fire safety.

Myth 2

Does not distinguish between solvent-based and water-based fire retardant coatings

There are two types of fire retardant coatings for steel structures, solvent-based fire retardant coatings and water-based fire retardant coatings. From the point of view of adhesion, solvent-based is greater than water-based, therefore, solvent-based fire-retardant coatings should be used for outdoor steel structures, and solvent-based or water-based fire-retardant coatings can be used for indoor steel structures.

The fire retardant coatings produced by some domestic manufacturers will decompose toxic gases when exposed to fire. If fire-resistant electrical products use this coating, in the event of a fire, toxic gases will be released. For example, the use of G60 perchloroethylene fire retardant coating, which has been eliminated, will decompose toxic chlorine gas in case of fire, so it cannot be used.

The quality of fire retardant coating construction also affects the fire performance of the material. Therefore, attention should be paid to the coating quality of fire retardant coatings. The coating methods of different fire retardant coatings are slightly different, but the basic construction points are the same.
