It is made of epoxy resin and polyester resin as the main raw materials, and has the common properties of both, so that the produced coating film has extremely good leveling, decoration, mechanical properties and strong corrosion resistance It is widely used in the coating of various indoor metal products. According to the properties of film-forming substances, it is divided into two categories: thermoplastic powder coatings and thermosetting powder coatings.
Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and Specialty powder coatings additives. The main characteristics of powder coatings are: harmless, high efficiency, resource saving and environmental protection. Or the appearance of the film-forming substance is divided into: matte type, high-gloss type, fine art type, etc.Powder coating classification Powder coating is a completely different form from general coatings, and it exists in the state of fine powder.
Thermoplastic powder coatings include: polyethylene powder coatings, polypropylene powder coatings, polyester powder coatings, polyvinyl chloride powder coatings, chlorinated polyether powder coatings, polyamide powder coatings, cellulose powder coatings, polyester powder coatings .. It has two categories: thermoplastic powder coatings and thermosetting powder coatings. It can also be divided into two categories according to the use environment: indoor type and outdoor type.
Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. There are many classification standards, and the names of various powders on the market are uneven. Since no solvent is used, it is called powder coating. Disadvantages: uneven powder on edges and corners, difficult to cover up film defects after curing, and high curing conditions. Thermosetting powder coatings include epoxy resin powder coatings, polyester powder coatings, and acrylic resin powder coatings
