Abstract:
1. A process for curing a curable polyureasil compound, the process comprising: (a) providing a mixture consisting of (i) a curable polyureasil compound comprising: (A) a hydrocarbon moiety comprising at least 2 urea groups bonded thereto, and (B) more than 6 hydrolysable silyl groups linked to the hydrocarbon moiety via at least one of the urea groups, (ii) an organic solvent for the curable polyureasil compound, (iii) water, (iv) a catalyst, and (v) optionally a corrosion inhibitor; and (b) curing the curable polyureasil compound with water, thereby hydrolyzing and condensing at least some of the hydrolysable silyl groups to form a cured polyureasil compound comprising covalent intermolecular siloxane crosslinks in the cured polyureasil compound.
