ABSTRACT:
The invention relates to a coating composition intended to be applied to a surface of a high-molecular-weight elastic body. The coating composition includes 100 parts by weight of a mixture of a polyisocyanate and a compound containing therein at least two active hydrogen atoms which are capable of reacting with the polyisocyanate to prepare a polyurethane, and 0.5-100 parts by weight of a diorganopolysiloxane having an average degree of polymerization from 6,000 to 10,000. The coating composition provides a coating film which is superior in durability. Furthermore, this coating film does not generate an uncomfortable noise even when a glass plate wet with water slides on the coating film.
