Disclosed is a carbamate functional silica, comprising repeating units: wherein R is H or an alkyl group of from 1 to 50 carbon atoms and n is a number from 1 to 100. Also disclosed is a functional silica comprising repeating units: wherein R is an alkyl group of from 1 to 50 carbon atoms, n is from 1 to 100, R1 and R2 may be the same or different and are at least one of a hydrocarbon group comprising from 1 to 100 carbon atoms with the proviso that at least one of R1 and R2 is not hydrogen. In one embodiment, R1 and R2 are hydrogen or the residual of an aminoplast polymer, an alkylating alcohol, or the like. Methods for making the disclosed functional silicas and coating compositions comprising the same are also provided.
