Powder coating powder composition analysis is resin. The main component of powder coating powder is resin, general resin accounting for about 50%, filling material accounting for less than 50%, pigment belongs to the category of filling material, accounting for 0.7% to 30%. Pure white pigments are the highest, and inorganic pigments are abundant.
Environmental protection you do not have to worry about, the environmental performance of powder coating powder is very strong, inorganic pigments including various metal oxides, chromate, carbonate, sulfate and sulfide.
Classification of powder coating powders
Powder coating powder is completely different from the general coating, it is in the state of fine powder. Because no solvent is used, it is called powder coating powder. The main characteristics of powder coating powder are: harmless, high efficiency, saving resources and environmental characteristics.
It has two categories: thermoplastic powder coating powder and thermosetting powder coating powder.
Thermoplastic powder coating powder is composed of thermoplastic resin, pigment, filler, plasticizer and stabilizer. Thermoplastic powder coating powder includes: polyethylene, polypropylene, polyester, PVC, chlorinated polyether, polyamide, cellulose, polyester and so on.
Thermosetting powder coating powder is composed of thermosetting resin, curing agent, pigments, fillers and auxiliaries. Thermosetting powder coating powder includes epoxy resin, epoxy polyester, polyester, polyurethane, acrylic resin, etc. Uneven powder on the corners of the defects, curing film defects difficult to cover up, high curing conditions, limited use of substrate.
Classification standards, the name of all kinds of powder on the market is uneven. According to the properties of film forming materials, it can be divided into two categories: thermoplastic powder coating powder and thermosetting powder coating powder. Or the appearance of the film is divided into extinction type, highlight type, art type, etc. can also be divided into two categories according to the use of the environment indoor type and outdoor type.
