The good conductivity of aluminum ensures that it adheres evenly to aluminum parts through electrostatic adsorption when powder coating.
Aluminum’s excellent heat resistance (melting point of 662°C) ensures that the workpiece will not deform during the baking process of powder coating.
Aluminum has a natural oxide film (Al₂O₃) on the surface, which has a certain roughness that helps powder coating adhere. After chemical treatment or sandblasting, an artificial conversion film is formed, which can further enhance the adhesion of powder coating to aluminum.
