What is Powder Coating?

- Sep 02, 2017 -

Powder coating is the use of dusting equipment (electrostatic spray machine) to spray the powder coating to the surface of the workpiece, under static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powder coating; powder coating after high temperature baking The effect of powder coating on the mechanical strength, adhesion, corrosion resistance, anti-aging and so on is superior to the painting process, the cost is also in the process of powder coating, With the effect of painting under.


The principle of electrostatic spraying on the dry powder adsorbed on the metal aluminum after 200 ℃ above the high temperature barbecue powder cured into a layer of about 60 micron thick solid bright coating. So that the product surface smooth and smooth color uniformity with a strong acid resistance, alkali resistance, crashworthiness, wear resistance can withstand long-term strong ultraviolet radiation and acid rain erosion does not appear coating powder, fade, shedding and so on. Powder sprayed aluminum profiles under normal conditions of service life of 30 years. The surface coating in 5 - 10 years to ensure that does not fade, do not change color, no crack. Its weatherability and corrosive are better than ordinary aluminum color diversification.
