High-Performance 2K Epoxy Coating System for Extreme Corrosion Protection
Our zinc-rich epoxy coating system combines two advanced components:
This dual-component system achieves 3,000+ hours salt spray resistance when formulated with zinc powder (zinc-rich version). Even the zinc-free variant maintains outstanding corrosion protection for general industrial applications.

The WL-AD224/WL-AC043 2K epoxy system demonstrates exceptional salt spray resistance, when formulated as a zinc-rich coating. Key experimental data highlights its corrosion protection performance:
| 26% 70% Zinc content test | |
| Neutral salt spray test | 2000h continuous testing |
| Initial water resistance | 2000h continuous testing |
| 40℃ water immersion | 2000h continuous testing |
Formulated without zinc additives, the WL-AD224/WL-AC043 2K epoxy system achieves high-build primer properties with exceptional tested performance metrics.
Test data of primer made of WL-AD224 and WL-AC043 2K epoxy combination:
Thick paste
Refers to the situation where the paint needs to be applied thickly, that is, the situation where the paint filmthickness of the carrier is relatively large, usually refers to a film thickness of more than 40-50 microns.
