The wet coating process

wet coating

First of all, it should be noted that the colour groups, surface finish and gloss level can be selected for wet coating in the same way as in the powder coating process. The exact specification of the coating can be designed in accordance with the technical requirements and customer preferences. The Technical Delivery Terms and Test Regulations for Anti-Corrosion Coatings on Steel Structures (TL/TP-KOR) and the specifications of the Federal Highway Research Institute (BASt) are often applied during the wet coating process. Regardless of this, layer systems can be implemented in consultation with the paint manufacturers.
