Zinni® AL 450 + Tridur® DB + Zintek® Top XT
Our best in class combined coating systems
No matter what kind of corrosion protection you need, we have the right solutions to meet all industry requirements. All various possible combinations of our exceptional product range ensure outstanding corrosion protection with an attractive appearance and durability. Our best-in-class combined coating system synergizes the alkaline zinc nickel coating, Zinni AL 450, the fluoride- and cobalt-free passivate Tridur DB, and the lubricated water-based topcoat Zintek Top XT in order to provide extraordinary corrosion protection behavior in several cyclic corrosion tests and in NSST of more than 1,500 h without base material corrosion.

Features and benefits
- The combined coating solution exhibits excellent cathodic corrosion resistance and reactive sealing properties, achieving high-level corrosion protection.
- The Zinni AL 450 alkaline zinc nickel electrolyte, optimized for barrel plating, shows a homogenous Ni incorporation of 12 – 15% and excellent current efficiency.
- The fluoride- and cobalt-free passivate Tridur DB for zinc nickel surfaces provides outstanding corrosion resistance against white rust (up to 1,000 h, even without sealer). Its low operation temperature (20 to 35 °C) helps reduce energy costs. The sustainable process also shows an extraordinary bath life.
- As an additional layer, the zinc flake topcoat Zintek Top XT exhibits best-in-class corrosion performance in cyclic corrosion tests and in NSST of more than 1,500 h. The water-based topcoat shows good performance after either cured at a moderate temperature of 150 °C, or at lower temperatures in drying centrifuges. Its integrated lubricant provides controlled friction properties.
