Powder-coating is to coat powdered paint on the workpiece with an electrostatic spray molding machine. The powder will be evenly attached to the surface in the electrostatic field. Final layers vary in effects according to different paint. The thickness reaches up to 60 microns after high-temperature drying, leveling, and curing, which makes the product surface flat and smooth with strong acid resistance, alkali resistance, and wear resistance, and can withstand long term UV radiation and acid rain without coating pulverization, fading, and falling off.
Powder coating is better than paint spraying in terms of mechanical strength, adhesion, corrosion resistance, aging resistance. The cost is also lower for the same effect. Powder-coating characteristics
- The final film is flat and smooth with very strong adhesion and excellent decoration performance, under the influence of electrostatic effect.
- Electrostatic adsorption reduces paint mist pollution and improves the workshop’s hygiene condition.
- Reduces cost by increasing paint utilization.
The paint is produced by processing hot extrusion, grinding, and sieving with a mix of specialized resin, pigment, fillers, curing agents, and other additives in certain proportions. It is a solid fine powder that is completely different from coatings in general, very stable at room temperature.
