▎ 摘　　要

NOVELTY - Passivation solution comprises boron nitride, epoxy resin, graphene, isocyanate-containing hyperbranched polymer grafted polyhedral oligomeric silsesquioxane POSS(RTM: Polyhedral oligomeric silsesquioxane)), and water. USE - The passivation solution is useful for stainless steel, catering, furniture, building, electric appliance, medical treatment, chemical engineering and aerospace fields. ADVANTAGE - The passivation solution has improved adhesive force, salt mist resistance, corrosion resistance, adhesion and corrosion resistance. The hyperbranched POSS(RTM: Polyhedral oligomeric silsesquioxane) containing isocyanate group contains a large amount of active group which is easy to be attached on the surface of the stainless steel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of passivation solution for stainless steel.
