Abstract:
1. An antistatic sol/gel forming coating composition comprising: (a) a hydrolyzate resulting from at least partial hydrolysis of a component A consisting of one or more compounds containing at least one polyalkylene oxide segment and at least two —Si(X) (b) optionally, at least one component B consisting of: or a hydrolyzate thereof, in which the R groups independently are monovalent alkyl groups, the Z groups independently are hydrolyzable groups or hydrogen atoms, and n′ is an integer equal to 0, 1 or 2, such that the Z groups do not all represent a hydrogen atom when n′=0; with or without one or more compounds of the formula: or a hydrolyzate thereof, in which the R1 groups independently are monovalent organic groups linked to the silicon atom through a carbon atom, the Y groups independently are monovalent organic groups linked to the silicon atom and containing at least one epoxy function, the Z1 groups independently are hydrolyzable groups or hydrogen atoms and m1 and n1 are integers such that m1 is equal to 1 or 2 and n1+m1=1 or 2; and (c) at least one inorganic metal salt; wherein component A and optional component B generate a cross-linked structure upon polymerization of the composition, the dry extract of the composition containing less than 5% by weight free polyalkylene oxide polymers.
