Aluminium Powder Coating Unit

Powder coatings, also called stove enamel finishes, adhere excellently to the substrate. They may be milled and offer both a high chemical and thermal resistance. Electrostatic polyester resins are sprayed on electrically grounded parts by means of compressed air. Electrostatic attraction makes a pre-defined amount of powder adhere to the component. In the smelting furnace the polyester resin is reduced into a fluid state and forms a continuous polyester resin film which is characterized by its high resistance against weathering and mechanical stress. Electrostatic powder coatings represent an environmentally sound technique as they do completely forego the use of solvents and are characterized by a highly efficient recovery of residual powder (about 98 %).
