▎ 摘  要

NOVELTY - A composition comprises shellac, resin, crosslinking agent and solvent, and optionally graphene. USE - Composition for suppressing corrosion rate of substrate e.g. coated cold-rolled steel. ADVANTAGE - The composition imparts excellent corrosion resistance to the substrate in saline environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the composition, which involves adding shellac to solvent (A) to obtain a solution, and adding the resin and the crosslinking agent, optionally along with solvent (B) and graphene to the solution.
