▎ 摘  要

NOVELTY - Self-stratifying anticorrosive coating comprises a zinc-rich epoxy, a curing agent including amine, thiol, phenol, and carboxylic anhydride, a binding agent including aminoalkyl dialkoxysilane, dimethoxysilane, and aminoalkyl trialkoxysilane, a graphitic material, a solvent, and a water scavenger. USE - Self-stratifying anticorrosive coating used in oil or gas fields for coating of equipment, such as oil rigs and pipes. ADVANTAGE - The self-stratifying anticorrosive coating DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for a self-stratifying anticorrosive coating on an associated substrate, which involves: (a) mixing together a monomer or a polymer, a solvent, a graphitic material, and sacrificial metal particles; (b) adding a material that prevents polymerization inside the coating before, and immediately after, application on the associated substrate; and (c) adding a silane mixture.
