Patent ID: 8609755

Claim:
A composition consisting essentially of: a) an aqueous solution of partial and/or complete condensate of ureidosilane of the general formula (I): wherein R 1 is a linear, branched or cyclic divalent organic group of 1 to 12 carbon atoms forming a stable bridge between ureido group X and the silyl group; each occurrence of R 2 independently is alkyl, aryl, or aralkyl group of from 1 to 16 carbon atoms; each occurrence of R 3 independently is hydrogen, acetyl, alkyl, or alkoxy-substituted alkyl group having from 1 to 16 carbon atoms; X is an ureido group of valence r selected from the group consisting of —NR(C═O)NR 2 , —NR(C═O)NR—, (—) 2 N(C(═O)NR 2 , (—) 2 N(C(═O)NR— and (—) 2 N(C(═O)N(—) 2 , wherein R is independently selected from the group consisting of hydrogen, alkyl group having from 1 to 6 carbon atoms, cycloalkyl group, alkenyl group having from 1 to 6 carbon atoms, arylene group and alkarylene group; r is an integer of from 1 to 4; and a is an integer of from 0 to 2, in the amount of from 0.01 to 80 weight percent and having no hazardous air pollutant in excess of 0.1 weight percent of the composition, wherein said aqueous solution is not stable and having visible precipitate or gel within a period of time from 1 week to 18 months; b) a stabilizing agent selected from the group consisting of alcohols, glycols, triol, polyols, glycol ethers, esters, ketones, pyrolidones and polyether silanes in the amount of from 1 to 50 weight percent; and, c) a colloidal cerium oxide in the amount of from 0.001 to 36 weight percent, wherein the stabilizing agent (b) stabilizes aqueous solution (a) to produce a stable composition which does not contain any visible precipitation or gelation for a period of time from 1 week to 18 months and wherein said weight percent amounts are based on the total weight of the composition.
