Abstract
An antifouling coating composition is provided comprising an organosilicon compound having a one end-blocked diorganopolysiloxane group and a condensation-curable silyl group in a common molecule, and optionally a heat-curable compound. The composition is applied and cured to a substrate to form a coat which has an improved surface protective function and durable water repellent and antifouling properties.
