Product Description
1.General introduction:
Powder coatings are mixed with a certain proportion of the resin, fillers, curing agents and other additives, then prepared by hot extrusion ,crushed and sieved.The products are stable at room temperature storage, then baking heat melted and solidified to form a smooth and bright permanent coating to achieve the purpose of decoration and corrosion.
2.Feature:
1).The products are non-toxic, solvent-free and non-toxic volatile substances,there are no intoxication, no fire, no "three wastes" emissions and other pollution problems, in full compliance with national environmental laws.
2). Raw material utilization is high, the highest utilization rate even more than 99%.
3). After being pre-coated handle, disposable construction, without primer,you can get a sufficient thickness of the coating, easy to automate operation, high production efficiency, reduce costs.
4). Dense coating adhesion, good impact strength and toughness, high coverage corners, with excellent resistance to chemical corrosion and electrical insulation properties.
5).Powder coatings storage and transport are safety and convenience.
3.Product series:
The products include high light ( above 86%),glazed (76%-85%),matte(20%-50%),low light (below 20%). We also offer a variety of shiny products according to the needs of users.
4.Powder physical properties:
Proportion : 1.2-1.8 (depending on the color and gloss ) .

9.Coating performance
| Epoxy Resin Powder Coatings Epoxy resin powder coating is a kind of thermosetting powder coating with corrosion resistance and toughness. It consists of epoxy resin, pigments and fillers, additives and curing agents. It has many advantages, such as strong adhesion, high hardness, scratch resistance, corrosion resistance, low melting viscosity, good leveling, no pinholes and shrinkage defects in the film, many kinds of patterns and colors, and can be prepared matte, bright, pattern, hammer pattern, etc. The thickness of the film can reach 50-300 um in one painting, and it can be recycled for uncoated powder. Mainly used in equipment and facilities, refrigerators and refrigerators, washing machines, radio, lampshades, bicycles and motor frame, automobile steering wheel, components and body, agricultural machinery equipment, pipeline external paint and so on. | ||||
