Abstract
The coating composition is prepared by partial co-hydrolysis and co-condensation of a mixture comprising an organotrialkoxysilane or its combination with a tetraalkoxysilane, a fluoroalkylalkoxysilane and a hydroxy-endblocked diorganopolysiloxane in the presence of an acid catalyst. The organopolysiloxanes thus prepared are suitable for coating plastic surfaces to produce a coating on the surfaces, the cured coating film having hardness as well as flexibility sufficient to ensure a very strong resistance to swelling, dissolution or corrosion by attacks of solvents and chemicals.
