NOVELTY - Coating comprises A component and B component in a mass ratio of (4-10):1. The A component comprises 0.5-3 wt.% graphene material, 20-40 wt.% zinc powder, 20-30 wt.% epoxy resin, 0.5-3 wt.% dispersant, 3-6 wt.% anti-settling agent, 10-30 wt.% filler and 20-30 wt.% organic solvent. The B component comprises 40-60 wt.% polyamide, 2-6 wt.% curing accelerator, 25-38 wt.% epoxy resin and 14-26 wt.% organic solvent. USE - The coating is useful for surface of the metal material as corrosion protection coating for the metal material (claimed). ADVANTAGE - The coating: has high impact strength, strong acid-base stability, and corrosion resistant.
