Patent ID: 7776148

Claim:
A curable composition based on hydrolysis products from organosilanes, comprising A. at least one product of the hydrolyzation of an organosilane of formula (A) R 1 a R 2 b SiX (4-a-b) (A) wherein R 1 represents a non-hydrolyzable radical, R 2 represents a non-hydrolyzable radical that includes a functional group and X represents the same or different radicals that are hydroxyl-groups or hydrolyzable groups, or oligomers therefrom, wherein a is 0 or 1, b is 1 to 3 and the sum of a and b can be 1, 2 or 3, and at least one substituent R 2 has an epoxy group; B. at least one blocked polyisocyanate, wherein the curable composition is characterized in that it contains a product of a hydrolyzation reaction, that was obtained through common hydrolysis of at least one organosilane of the formula A; and C. optionally not more than 50% based on the solid content of A by weight of a component selected from the group consisting of: at least one silane of formula SiX 4 , wherein the radical X is defined as in the case of formula (A); at least one silane wherein the compound has no epoxide ring; at least one aromatic or aliphatic diol; hydrolyzable chemical compounds, and combinations thereof, wherein at least one substituent R 2 has a functional group selected from the group consisting of: ether-, amino-, monoalkylamino-, dialkylamino-, amido-, mercapto-, thioether-, vinyl-, acryloxy-, methacryloxy-, cyano-, halogen-, aldehyde-, alkylcarbonyl-, sulfonic acid- and phosphoric acid-group, wherein said functional groups are directly linked to the silicon atom via an alkylene-, alkenylene- or arylene- bridge, that can be interrupted by an oxygen-, sulphur- or —HN-group, and wherein the radicals R 2 have 1 to 18 carbon atoms.
