The Delta-Protekt 170 RT zinc flake coating is brushed on the surface by spray application. Depending on the thickness of the coating, it dries at 20 to 25°C within approx. 20 to 60 minutes. According to Dörken MKS, a drying oven is not required. Additionally, a suitable topcoat can be applied, which increases corrosion protection and improves other properties such as chemical resistance, appearance and feel.

The second product innovation is the zinc flake contained in the Delta-Protekt Repair spray can. This corrosion protection enables the coating of bare metals, especially for the repair of defects after the coating and handling process. This product can also be used for small area coating of preassembled component groups which must not be exposed to high baking temperatures. This zinc flake coating also dries at room temperature and offers cathodic corrosion protection as a repair for Dörken MKS Basecoats.

According to the manufacturer, both zinc flake coatings achieve good test results in the laboratory and at least 720 h without base metal corrosion in the salt spray test (according to DIN EN ISO 9227).
