crosslinkable coating composition, method for manufacturing a crosslinkable coating composition, coating, and use of a coating composition or coating.

摘要

A cross-linkable coating composition comprises (i) one or more silanes having either at least three hydrolysable groups, or at least two hydrolysable groups and at least one organofunctional group capable of forming chemical bonds upon curing, wherein (i.a) the sum of said silanes constitutes at least 20% of the total mass of the coating compositions combined solids and silanes, and (i.b) said silanes are possibly partly or completely hydrolyzed and possibly partly condensed, and (ii) at least one low surface energy additive, wherein (ii.a) said low surface energy additive comprises polydimethylsiloxane chemically bonded to at least one functional group, (ii.b) said functional group is configured for the polydimethylsiloxane moiety to cross-link with said coating composition, (ii.c) said polydimethylsiloxane constitutes 0.01% to 15% of the mass of said cured coating, when said coating composition is cured, and (ii.d) said polydimethylsiloxane moiety has a molecular weight of more than 1600 g/mol.
