Dip coating process

In the conventional dip coating process, the workpieces - for example, window frames or even electrical windings - immersed in the paint and pulled out again. At the end of this process, the object is practically finished.

The dip-coating process uses both solvent-based and water-based dip coatings. The advantage of this process is the high degree of automation and the complete painting of the workpieces with very low paint losses (no overspray).

In order to ensure a high-quality and consistently good painting result, however, some important criteria must be taken into account. First, the component or substrate to be coated must be absolutely clean. Any impurities present would accumulate in the bath and adversely affect the coating process. In order to ensure a constant bath quality, therefore, both the paint to be applied and evaporated solvent or water must be continuously replenished. Permanent circulation prevents sedimentation in the low-viscosity bath.
