Fireproof coating is a type of coating that can improve the fire resistance of materials, slow down the spread of flames, or prevent combustion within a certain period of time by brushing the coating on the surface of the material. This type of coating is called fireproof coating or flame retardant coating. Fireproof coating is a special coating used on the surface of combustible substrates, which can reduce the flammability of the coated material surface, block the rapid spread of fire, and improve the fire resistance limit of the coated material. Applied to the surface of combustible substrates to change the combustion characteristics of the material surface and prevent the rapid spread of fire; Special coatings applied to building components to improve their fire resistance limit are called fireproof coatings.
