Powder coatings are high-quality, thermosetting coatings designed for superior surface finishing. They are formulated using synthetic resins, pigments, and specialized additives, yet they contain no organic solvents whatsoever. This makes them an environmentally friendly choice, offering benefits such as being solvent-free, pollution-free, recyclable, energy- and resource-efficient, reducing labor intensity, and delivering coatings with exceptional mechanical strength. The manufacturing process of powder coatings involves three key steps: pre-mixing raw materials, extrusion, and pulverization. Additionally, the particle size distribution of the powder is carefully controlled to meet specific application requirements. Typically, powder coatings are applied by spraying them onto the surface of a workpiece using an electrostatic gun. Once the workpiece reaches a temperature range of 120–200°C, the powder melts and subsequently cures through chemical cross-linking, forming a durable, smooth finish.
Overview of Powder Coatings Powder coatings are manufactured using synthetic resins, pigments, and specialized additives—forming a solvent-free powder that is a high-quality, thermosetting coating designed for superior surface treatment. They feature characteristics such as being free of solvents, environmentally friendly, non-polluting, recyclable, energy- and resource-efficient, reducing labor intensity, and offering excellent mechanical strength in the applied film. The manufacturing process involves three key steps: raw material pre-mixing, extrusion, and pulverization, with the powder particle size distribution carefully controlled to meet diverse application requirements.
The use of powder coatings typically involves applying the powder onto the surface of a workpiece using an electrostatic gun, followed by melting the coating as the workpiece reaches a temperature of 120–200°C, and finally solidifying it through chemical cross-linking. It’s convenient to use and delivers outstanding results.Powder Coating Production Process

Characteristics of Powder Coatings 1. This product contains no toxins, solvents, or volatile toxic substances, eliminating concerns such as poisoning, fire hazards, and the emission of "three wastes," thus fully complying with national environmental protection laws.
2. Our company boasts high raw material utilization—powders produced here can have their overspray efficiently recycled, achieving a maximum utilization rate of over 99% in some cases.
3. After pre-treatment of the substrate, a single-step application can achieve sufficient coating thickness without the need for a primer, making it easy to automate the process, boosting production efficiency, and reducing costs.
4. The coating features excellent density, adhesion, impact resistance, and toughness, with high edge and corner coverage. It also boasts superior resistance to chemical corrosion and outstanding electrical insulation properties.
5. Powder coatings are safe and convenient to store and transport.Product images 
Advantages of Powder Coating 1. Healthy and Eco-Friendly
It eliminates the need for various liquid chemical additives—such as film-forming agents, dispersants, wetting agents, leveling agents, and anti-corrosion and anti-mold additives—that are typically added to achieve desired coating performance.
2. Convenient for transportation and storage
Typical coatings contain about 20–50% water, whereas in powder coatings, this water is added only at the point of use on-site—meaning it doesn’t need to be transported or stored. Additionally, water-based coatings often freeze and become damaged when transported or stored at temperatures below 0°C, but latex powder coatings do not suffer from this issue.
3. No preservatives required
In traditional liquid coatings, both water and nutrients for bacteria are present, making them prone to bacterial contamination. Therefore, to prevent spoilage, preservatives must be added. In contrast, latex powder coatings eliminate the risk of bacterial contamination altogether, so they don’t require preservatives.
4. Coating Odor
Compared to the lingering odor typically associated with conventional paints, this paint dissipates very quickly—truly making it a "paint-and-go" solution.Storage of Powder Coatings 1. Keep away from fire sources and avoid direct sunlight; store in a well-ventilated area at temperatures below 35°C.
2. Avoid storing in places susceptible to contamination by water, organic solvents, oils, and other materials.
3. After using powder coatings, do not leave them exposed to the air unnecessarily; always keep the container tightly sealed or securely tie the bag opening to prevent foreign objects from getting mixed in.
4. Avoid prolonged skin contact; if powder does get on the skin, rinse thoroughly with soapy water—never use solvents.
5. All equipment used in coating operations must be properly grounded to eliminate static electricity.
6. Avoid unintended discharge phenomena in the coating machine.
7. In the powder coating room, keep the concentration of airborne dust as low as possible below the safety threshold to prevent the risk of dust ignition and explosion.
