Blending paint brush just iron on why cracking

Steel surface painting coating classification general steel coating is divided into two categories: a class belongs to the protection class coating; a number of use class coating. Protection class such as building construction belongs to the protection class coating treatment, the main purpose is to prevent oxidation. The scope of the use of class is very wide, home appliances, medical equipment, furniture, machinery and equipment, cars, boats, airplanes, trains and so on related to the scope of too many. Protective coatings used for protective coatings of many materials, mainly phenolic, polyester, etc. can be used for antioxidant coating treatment. Phenolic antirust paint, polyester antirust paint and so on. At present, there are a lot of new materials in the new environmental protection category. By the oil-soluble into a water-soluble more conducive to environmental protection. Use of coatings to use coating materials or nitro-based materials, new materials also have polyester environmental protection materials. At present, the processing of new materials using the coating is also more. Many steel finishes have not used the traditional form of painting. Better use of plastic spraying materials to deal with the surface of steel materials. Including some mechanical equipment, the finish coatings have been updated from the traditional painting to the thermoplastic processing form to meet some special needs. Traditional coatings traditional phenolic blending paint is fully capable of being used as a primer for some steel material coatings. Phenolic primer material processing is the most economical.
