Patent ID: 7501480

Claim:
An autocatalyzed, thermally curable composition free from external catalysts and comprising 10 to 80% by weight, based on the total weight of the composition, of at least one condensate of at least one silane consisting of silane selected from the group of silanes which contain at least one of hydrolyzable atom and one hydrolyzable group and also at least one (i) nonhydrolyzable, isocyanate-adduct-group-free group with at least one epoxide group, and at least one nonhydrolyzable, epoxide-group-free group with at least one group selected from the group consisting of (a) divalent linking urethane groups —NH—C(X)—X—and —X—(X)C—NH—, and (b) divalent linking urea groups —HN—C(X)—NH—, in which the variable X stands for an oxygen or sulfur atom; (ii) nonhydrolzable group with at least one epoxide group and at least one group selected from the group consisting of the groups (a) and (b), and (iii) nonhydrolyzable, isocyanate-adduct-group-free group with at least one epoxide group, at least one nonhydrolyzable, epoxide-group-free group with at least one group selected from the group consisting of the groups (a) and (b), and at least one nonhydrolyzable group with at least one epoxide group and at least one group selected from the group consisting of the groups (a) and (b); and 0.1 to 20% by weight, based on the total weight of the composition, of a binder.
