Zn flake
High Corrosion Resistant Coating with Zinc Flake System
1. What is Zn flake Coating?
Zn flake is a proprietary eco-friendly water-based coating slurry comprised of dispersed zinc(or/and aluminum) flakes and inorganic matrix binder. Applied as a composite slurry, the coating becomes totally hard inorganic after drying & curing. Zn flake coating is composed of multilayer of zinc flake which is 15§­ in diameter and 0.5 §­ in thickness.
