The powder coating uses the principle of electrostatic spraying to adsorb the dry powder on the metal aluminum profile. After baking at a high temperature of 200 ° C or higher, the powder solidifies into a thick and bright coating of about 60μm thick.
The surface of the sheet metal parts is smooth and smooth, and the color is uniform. It has strong acid resistance, alkali resistance, crash resistance and wear resistance. It can withstand the strong ultraviolet radiation and acid rain for a long time without the phenomenon of powdering, fading and falling off of the coating.
Powder coated sheet metal parts have a service life of 30 years under normal conditions. The surface coating is guaranteed to be fading, non-discoloring and cracking within 5-10 years. Its weather resistance and corrosivity are better than ordinary aluminum color diversification.
