During the liquid coating process, aluminium components are coated with a liquid lacquers. This is afterwards baked in an industrial oven. The applied coat forms a protective layer on the substrate. In order to ensure perfect lacquer adhesion and good corrosion protection, the aluminium surface is usually pre-treated with a aluminium chromate beforehand. If a chromate-free pre-treatment is desired or if there is a risk of filiform corrosion, we work with pre-anodisation instead.
The range of design possibilities for colours, gloss effects or surface structures is enormous with this process. In terms of aesthetics and depth effect, they far surpass powder coatings.
Almost every surface can be created individually in any colour hue, tint or shade and can combined with equally individual metallic effects and surface haptics. Thereby, liquid coating systems show a great depth effect, especially with metallic effects.
Fluoropolymer coatings are among the most weather-proof and durable surfaces. Our special expertise lies in the application of the GSB-certified fluoropolymer system DURAFLON®. DURAFLON® can be produced in an almost unlimited range of colours. In addition, the visual and functional qualities of the coating are maintained over the entire service life of the façade. We are also a licensed partner of PPG Industries for the processing of PVDF®-fluoropolymer coatings.
HDP coatings are comparable in durability to some of the better lasting powder coatings (dt. “hochwetterfest”). Decorative surfaces with metallic effects can be created. HD Wahl offers a range of different wet paint finishes.
The weather resistance of PUR coatings is comparable to that of PE powder coatings. The PUR quality is mainly suitable for indoor use.
