Aluminium alloys are extensively used in space programs for both structural and non-structural applications. As well known, the corrosion resistance of these alloys is quite limited and anticorrosion treatment is needed. The most used treatment currently used for improving the corrosion resistance of aluminium alloys are usually chromate (CrVI-based) conversion coatings (CCC). Due to the […]
One of the most important factors influencing paint adhesion and corrosion resistance is surface preparation. To ensure optimum performance and long-term environmental resistance, metal substrates must be free of organic and inorganic contaminants. To prepare a surface one can basically choose between 2 options, blasting or chemical pretreatment. Mechanical/Blasting – Abrasive particles (sand, grit […]
PreCoat Z31 for galvanized steel: First in Europe AD Chemicals (chemical supplier) and Weert Group (galvanizer and powder coating applicator) are introducing an innovative chromium (VI)- free pretreatment system prior to powder coating on galvanized steel (Duplex-system). Weert Group is the first galvanizer in Europe to implement this new technology that complies with both […]
AD Chemcials will be present at EUROFINISH 2017. AD Chemicals will demonstrate its new innovations for chromium(VI) free pretreatment of galvanized steel. Furthermore we will show our PreCoat F31/20 and Z31/20 for grit blasted steel. Eurofinish is organized bij VOM (Belgian association for surface finishing techniques) and takes place the 10th and 11th of […]

Again, there will be a large event where innovations for the coatings and ink industry will appear in the spotlight. This time the theme […]
Abstract It is well known now that some well described Qualicoat pretreatment procedures are very critical in obtaining good adhesion of powder coating and sufficient corrosion protection. Proper etching/pickling to remove the most sensitive Aluminium top layer and sufficient rinsing are two of these important pretreatment steps. Even though job coaters are following Qualicoat procedures […]
