▎ 摘　　要

NOVELTY - Curable coating composition comprises: (a) a nanoparticle-polymer composition, comprising (a1) the reaction product comprising (a1.1) at least one epoxy resin, (a1.2) at least one hydroxy-terminated poly(dimethylsiloxane) (PDMS) and (a1.3) at least one silane coupling agent, and (a2) at least one hybrid nanofiller, comprising graphene nanoplatelets (GNP) and nano-silica (NS); and (b) optionally, super amphiphobic nanoparticles, comprising the reaction product of comprising (b1) silicon dioxide nanoparticles and (b2) 1H,1H,2H,2H-perfluorodecyltrichlorosilane and/or 1H,1H,2H,2H-perfluorododecyltrichlorosilane. USE - The composition is useful in cured coating composition for coating an object, preferably coating the surface of a substrate, where the substrate is a metal substrate (all claimed). ADVANTAGE - The composition provides the substrate with improved mechanical protection properties, corrosion protection properties, water repellency and/or oil repellency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for coating the surface of a substrate comprising applying the composition to at least a part of the surface of the substrate to form a first coated surface, curing the first coated surface to form a cured first coated surface, optionally, applying the superamphiphobic nanoparticles to the cured first coated surface to form a second coated surface, and curing the second coated surface.
