Cathodic electrocoating: a process for the highest quality standards

Electrocoating offers optimum surface sealing and therefore first-rate corrosion protection. Thanks to the even, thin coating, the surface can still be painted, e.g. in another colour. And it is extremely environmentally friendly: 

the immersion process results in a high utilisation ratio and the water-soluble coating system keeps the proportion of organic solvents very low.
