Polyorganosiloxane composition, cured product of the composition, and method for producing the composition, use of the composition in preparing adhesive

The present invention provides a cured body of excellent heat resistance and cold resistance and a high strength, high transparency, and can be used for bonding glass, metal and resin, and thus can be manufactured at low cost polyorganosiloxane was cured body of the composition, method of producing the composition, and the composition is in the preparation of an adhesive; polyorganosiloxane composition comprising (a) at least one end of the molecule has been silanol-modified polyorganosiloxane and (B) with respect to 1 mol of said polyorganosiloxane is from 0.5 mol to 4.0 mol of the metal alkoxide, and a molecular weight polyethylene fraction of the mass of organosiloxane average (Mw) of 1,000 or less, the metal alkoxide is titanium alkoxide or tin alkoxide, the polyorganosiloxane composition is produced by a production method including the following steps, this step is: having a metal with oxygen in the range of between connecting metal alkoxide (M) to silicon (Si) MO-Si bond, polyorganosiloxane and a metal alkoxide stirring step, and the polyorganosiloxane composition by oxygen having a connection between a metal alkoxide of metal (M) and silicon (Si) Up MO-Si bonds.
