Powder coatings have a completely different form from ordinary coatings, which exist in the state of micro-fine powder. Since no solvent is used, it is called powder coating. It is a new type of solvent-free, 100% solid powder coating. It has the characteristics of not using solvent, harmless, non-polluting, saving energy and resources, environmental protection, reducing labor intensity and coating film mechanical strength and so on. Because it is 100% solid powder coating, it can be sprayed automatically, oversprayed or oversprayed, and can also be recycled with a recovery system to recycle the excessive part of the coating, reducing environmental pollution, convenient and convenient, and it is a kind of coating worthy of promotion.

Thermosetting powder coating is generally composed of resin, curing agent, pigment, filler and additives. It is a hard coating formed by heating thermosetting resin as a film-forming material and adding a curing agent that reacts with cross-linking. It has good decorative properties, and because the low molecular weight prepolymer can form a network of cross-linked macromolecules after curing, it also has good corrosion resistance and mechanical properties.

Forms of thermoset powder coatings

Healthy and environmentally friendly: eliminating the need to add various liquid chemical harmful film-forming, dispersing, wetting, leveling, anticorrosion and mildew additives in order to achieve the performance of coatings.

Convenient transportation and storage: ordinary coatings contain about 20-50% of water or solvent, while the powder coating, neither water nor solvent, completely solid, convenient and safe transportation, in addition to water or solvent containing coatings, when the temperature of transportation and storage is lower than 0 ℃, often freezing, powder coating does not have this problem.

No preservatives: In traditional liquid coatings, there is both water and bacterial food, which is easily contaminated by bacteria. Therefore, in order to prevent deterioration, to add preservatives, while latex powder coating without bacterial contamination problems, do not need preservatives.

Paint Odor: Compared with the traditional paint odor residue, this coating can be dispersed quickly, so it can be said that it is painted and eliminated.

Recyclable: During the spraying process, the powder coating can be recycled through the special recycling device, and the recycled powder can be mixed into the new powder in a certain proportion to realize the secondary use. This greatly reduces the cost of use and improves the utilization rate of the coating.
