WEICON Zinc Spray

Overview

WEICON Zinc Spray is approved by the German TÜV and provides all metal surfaces with long-lasting cathodic corrosion protection. It forms a fast-drying, adherent protective layer of microfine zinc flakes that resists extreme weather and environmental conditions. Metal parts coated with WEICON Zinc Spray showed no signs of corrosion even after more than 1,050 hours in the salt spray test to DIN EN ISO 9227, and it fulfils higher requirements than those defined by DIN EN ISO 1461. It can be used indoors and outdoors and needs no primer or top coat.
