Induction drying of paints and primers on metal surfaces is particularly applicable in the production of profiles and pipes, i.e. elements whose drying in chambers and drying rooms is problematic due to their dimensions. The advantage of induction heating is drying by heating the paint from the substrate side and not from the side of the coating as is the case with e.g. hot air drying. This results in efficient evaporation of the solvent or water in the case of water-based emulsion paints.

This technology is used in the processes of applying protective primers in the production of steel profiles and pipes and also in drying steel constructions.
