<p>Disclosed is a process for manufacturing a coating composition, wherein the process comprises the steps of: (i) forming a reaction mixture comprising water, first quatemary silane and second quatemary silane, wherein the first quatemary silane has formula (I), Si(R1)4 (I) wherein each R is independently selected from alkoxy and halogen; and the second quatemary silane has formula (II), (R1)4 -m Si(R2)m (II) wherein each R1 is independently selected from alkoxy and halogen; R2 comprises at least 2 carbon atoms and is selected from alkyl, alkenyl, fluoroalkyl, fluoroalkenyl, aryl, fluoroaryl and combinations thereof; and m is an integer from 1 to 3; (ii) hydrolyzing the reaction mixture under basic conditions; and then (iii) continuing the hydrolysis under acidic conditions.</p> |
