Metal restoration coatings

Fireproof coatings are divided into the following three groups according to their scope of application:
  1. Fireproof coatings
  2. Fire retardant coatings
  3. Heat resistant coatings
Polymer fire retardant coatings include coatings that are fire and heat resistant and protect the underlying surface during a fire. They are used to maintain their function and prevent the transfer of heat and fire to the lower surface. For example, in transmission pipelines, if the pipe catches fire, they remain leak-free despite the fire-fighting coating. These polymer coatings are usually based on phenols that have high heat and corrosion resistance and their heat transfer coefficient is low even at high temperatures. Fire retardant coatings Only prevent fire from spreading and flaming surfaces, and have the property of extinguishing themselves so that they do not allow the surface to catch fire. However, the mechanical and chemical properties of the substrate may be reduced by heat transfer. These coatings are usually based on halogenated and non-halogenated materials. Halogenated coatings contain halogens that produce toxic fumes when exposed to fire and are therefore not recommended for indoor environments. Non-halogenated coatings contain compounds of minerals such as nitrogen, phosphate, aluminum, etc. that do not emit fire and toxic fumes and prevent the formation of foam coal to prevent ignition and partial heat transfer to the substrate. Heat-resistant coatings can also be used at high temperatures, depending on the type of polymer material used in them, so that their temperature tolerance can be increased up to 300 ° C. These coatings are based on novac or modified resins. In fact, these coatings are used in environments that are exposed to high temperatures to withstand heat, but they are exposed to flames and can not be used in environments that are exposed to direct flame. Depending on the required use, these coatings can be used to protect a variety of metal, non-metallic, wood, stone, etc. surfaces. The company uses a variety of phenolic resins, Novalac epoxy resins and resolutions, non-halogenated mineral powders and chlorinated compounds to design a variety of fire protection systems and components.
