▎ 摘  要

NOVELTY - Restorative and protective composition comprises: a curable silicone silane having silanol groups; a graphene slurry; an adhesion promoter; and a carrier that is liquid at 20° C at atmospheric pressure in which the curable silicone silane, the graphene slurry, and the adhesion promoter are dissolved or dispersed. USE - The composition is useful for applying restorative and protective coating to target substrate i.e. article e.g. vehicle trim piece, tire or headlight or vehicle exterior trim or plastics (all claimed). ADVANTAGE - The composition utilizes graphene in powder forms or solvent based slurry that to low surface energy of graphene also complements silicones in film coating to inhibit dirt and debris adhesion and hardens the resulting film coating against abrasion, thus significantly improving trim and molding restoration composition, and graphene can to adjust hydrophobic or hydrophilic properties of the treated surfaces, as result, treated surfaces shed dust naturally, look cleaner/fresher and require less manual maintenance and have excellent mechanical strength and flexibility, thermal and electric conductivities, and much higher optical cross section relative to many polymer coatings. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: applying a restorative and protective coating to a target substrate comprising applying the composition to the target substrate and allowing sufficient time for composition to cure onto the target substrate; and article comprising a vehicle trim piece or a vehicle tire or a headlight and a coating resulting from the cure of the composition adhered to a surface of the vehicle trim piece or the vehicle tire or the headlight.
