White RAL 9010 Corrosion Resistance Epoxy Powder Coating for Automotive Painting
Classification of powder coatings:
Powder coatings are completely different from general coatings and are present in the form of fine powders. Since no solvent is used, it is called a powder coating. The main features of powder coatings are: harmless, high efficiency, resource saving and environmental protection.
It has two broad categories: thermoplastic powder coatings and thermosetting powder coatings.
Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester, and the like.
Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and auxiliaries. The thermosetting powder coating includes an epoxy resin, an epoxy-polyester, a polyester, a polyurethane, an acrylic, and the like.
There are many classification standards, and the names of various types of powders on the market are uneven. According to the properties of film-forming materials, they are divided into two categories: thermoplastic powder coatings and thermosetting powder coatings. Or the appearance of the film-forming substance is divided into: matt type, high-gloss type, art type, and the like. Can also be divided into two categories according to the use environment: indoor and outdoor.
characteristic of powder coating:
1. The product is non-toxic, free of solvents and volatile and toxic substances, so there is no pollution, no fire, no "three wastes" and other pollution problems, fully in line with the requirements of the National Environmental Protection Law.
2, high raw material utilization rate, powder produced by some well-known brands of powder suppliers, its overspray powder can be recycled, the highest utilization rate can even reach more than 99%.
3. After pre-treatment of the coated object, one-time construction, without the need of primer, can obtain a coating film with sufficient thickness, easy to achieve automatic operation, high production efficiency, and can reduce cost.
4, the coating is dense, adhesion, impact strength and toughness are good, corner coverage is high, with excellent chemical corrosion resistance and electrical insulation properties.
5, powder coating storage, transportation is safe and convenient.
