It is used to prepare aluminum parts for electrostatic powder coating process. The aluminum surface needs to be degreased and  cauterised(1g / m2). The coating bath without chrome plating should be installed with deionized water. Deionized water should be used in the rinse bath prior to coating. After coating, the aluminum parts are taken into drying ovens without rinsing and are ready for electrostatic powder coating. Provides high corrosion resistance.
