The individual body parts of an automobile have to be carefully cleaned of dirt, dust and other foreign matter and then properly prepared for the subsequent painting operation. Henkel says it offers optimised pre-treatment processes adapted to the requirements of its partners in the automobile industry. The company has developed a two-stage pretreatment process, which allows the two materials employed to be pre-treated in sequence, thus avoiding sludge waste. Henkel claims smaller amounts of chemical are required, which makes the process more effi cient, safer for employees and also more environmentally friendly.
