Zinni® 220 + Tridur® DB + Sealer 350 WL8
Outstanding corrosion protection with an attractive appearance and durability
We provide perfect corrosion protection solutions that meet industry requirements. Our diverse product range allows for various combinations, ensuring exceptional protection, appealing appearance, and durability. For example, our high-performance silver coating systems combine Zinni 220, ammonia and boric acid-free acid zinc nickel coating, with Tridur DB, a fluoride- and cobalt-free passivate. This combination is further enhanced by Sealer 350 WL8, a lubricated water-based hybrid sealer. With this powerful combination, you can expect corrosion protection exceeding 720 hours in the NSS test, without any base material corrosion. It also demonstrates exceptional performance in cyclic corrosion tests. Rest assured that our reliable and effective solutions will meet and exceed your expectations for corrosion protection in any industry.

Features and benefits
- Economic zinc nickel solution with excellent corrosion protection and adjusted coefficient of friction values
- Zinni 220, an ammonia and boric acid-free acid zinc nickel process with homogenous nickel incorporation, offers an attractive appearance and exhibits improved throwing power.
- Tridur DB is a fluoride- and cobalt-free passivate for zinc nickel surfaces that provides outstanding corrosion protection against white rust up to 1,000 h in NSST, even without a sealer applied. Its process operation temperature ranges between 20 and 35 °C, reducing energy costs. Its extraordinarily long bath life also emphasizes the sustainability of this process.
- Sealer 350 WL8 is a water-based hybrid sealer with an advanced covering power for black passivates, improved corrosion resistance by Lotus effect technology, and an integrated lubricant for controlled friction properties.
