| ZACOT |
| High Corrosion Resistant Coating with Zinc Flake System |
|
|
 |
|
| 1. What is ZACOT Coating? |
| ZACOT 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. ZACOT coating is composed of multilayer of zinc flake which is 15㎛ in diameter and 0.5 ㎛ in thickness. |
