Zinc Flake Technology – Base Coats
The Basis for the Highest Corrosion Protection
Zintek® base coats are highly reactive systems with combinations of zinc and aluminum flakes. The metal particles and reactive mineral resins react on steel base material to form an adhesive bonding. During baking a conductive zinc aluminum layer is formed providing sacrificial protection to the steel. The typical curing temperature for the solvent based products is approx. 230 °C –preventing the softening of the hardened steel parts. The waterborne Zintek 800 W needs approx. 300°C curing temperature.
The coatings are Pb-, Hg-, Cd- and Cr(VI)-free and provide corrosion resistance values from 240 h to over 1,000 h to base metal corrosion and from 120 h to over 240 h to white rust. Zintek® base coats can be combined with inorganic and organic top coats – for highest corrosion protection with multipurpose properties, such as defined friction values.
