The corrosion-resistance, adhesiveness and quality of a varnish coating are determined by the subsurface, which needs to be suitably pre-treated and cleared of greases, oils, separating agents, dirt and layers of corrosion:
These processes mechanically remove corrosion products and impurities:
Chemical pre-treatments form conversion coatings that serve as an optimum primer for the varnish, while also offering a high degree of protection against corrosion:

The processes are combined as necessary on a case-by-case basis to obtain the ideal outcome for the respective application. As the effectiveness of the pre-treatments is not permanent, the varnish coating is applied straight after the pre-treatment.Services
