Modern chemical autodeposition processes have evolved into a powerful alternative to cathodic dip coating (e-coating). Especially in cases where uniform coating of interior surfaces and edges is required, or where powder topcoating is used, they can deliver significantly better corrosion protection results. In Germany, companies like Räckers and BBL have therefore opted for the non-electric Aquence technology from Henkel, a sustainable coating process that additionally does completely without hazardous heavy metals.
