Zinni® AL 450 + Unifix® Ni 3-30L + Sealer 350 WL8
Uniform black coating with outstanding corrosion protection
Our high-performance plating solution combines an alkaline zinc nickel layer, Zinni AL 450, with the Unifix Ni 3-30L passivate, forming the foundation for exceptional corrosion protection. Adding Tridur ZnNi H5.2 as an intermediate layer and Sealer 350 WL8 as the finishing touch enhances corrosion resistance through barrier protection and the Lotus effect. The result is a uniform black appearance with outstanding corrosion protection exceeding 720 hours without any base material corrosion. Sealer 350 WL8 features an integrated lubricant that provides a controlled coefficient of friction properties. It is approved according to GMW 4700 Type B Code G and meets the requirements of VDA.
