摘要：Composition comprises: a silane derivative (I) and/or its hydrolysis and/orcondensate product; a silane derivative (II); a colloidal inorganic oxide, fluoride oroxyfluoride; an epoxide compound containing at least two epoxide group; and a catalystsystem comprising a Lewis acid and a thermolatent Lewis-acid base adduct. Compositioncomprises: a silane derivative of formula (Si(OR1)(OR2)(OR3)(OR4)) (I) and/or its hydrolysisand/or condensate product; a silane derivative of formula ((R6R7) 3 - nSi(OR5) n) (II); acolloidal inorganic oxide, fluoride or oxyfluoride; an epoxide compound containing atleast two epoxide group; and a catalyst system comprising a Lewis acid and athermolatent Lewis-acid base adduct. R1-R5 : alkyl, acyl, alkylacyl, cycloalkyl, aryl oralkylaryl (all optionally substituted); R6 : organic group comprising an epoxide unit,preferably a silane derivative of formula (III); R7 : optionally substituted alkyl, cycloalkyl,aryl or alkylaryl; n : 2 or 3; R12 : H or 1-4C-alkyl; and R13 : 1-10C-alkyl. Independent claimsare included for: (1) coating a substrate comprising providing the composition, applyingthe composition on the substrate and treating the substrate at 75-150[deg] C for
hardening the coating; and (2) an article comprising a substrate and the coating on thesurface of the substrate, which is obtained by the above process. [Image].
