Abstract
A polyorganosiloxane compound obtained by allowing a polyorganosiloxane having silicone resin structure to react with a polyorganosiloxane having silicone oil structure in the presence of a hydrosilylation catalyst, and having the both structures in the molecule. Also disclosed is a coating composition including the polyorganosiloxane compound, a silane or silicone resin having an RO—Si group, and a curing catalyst. The former polyorganosiloxane compound is compatible with silicone resins. The latter coating composition can provide coatings improved in flexibility without lowering the curability, surface hardness and weatherability inherent in silicone resins.
