Abstract:
1. A coating composition comprising: A) a self-assembled silica condensate formed by the hydrolysis of a reaction mixture comprising a tetraalkoxy orthosilicate and at least two medium to long chain trialkoxy silanes having a structure according to formula (1): wherein each R is independently an alkyl group having 1 to 4 carbon atoms and R B) a film-forming binder comprising: a crosslinkable component, wherein the crosslinkable component is a compound, oligomer and/or polymer comprising one or more functional groups selected from hydroxyl groups, amine groups, epoxy groups, carboxylic acid groups, anhydride groups, aspartate groups, acetoacetate groups, orthoester groups, and thiol groups; and at least one crosslinking component comprising functional groups capable of reacting with the functional groups of the crosslinkable component to form a crosslinked network, wherein the crosslinking component is a melamine resin or a compound, oligomer and/or polymer comprising one or more of carboxylic acid groups, anhydride groups, isocyanate groups, blocked isocyanate groups or combinations thereof.
