PROBLEM TO BE SOLVED: To firmly adhere without roughening treatment and an adhesive assistant and reduce irregularity in hardness of a rubber by simultaneously extruding a vinyl group-containing organopolysiloxane, an organohydrogen polysiloxane which contains hydrogen atom combined with a silicon atom, and a composition of a platinum catalyst. SOLUTION: An addition reaction type organopolysiloxane composition which contains a vinyl group-containing organopolysiloxane 100 pts.wt. which is shown by a formula 1 and contaxns 0.5-3.0mol% of vinyl group (R<1> represents a monovalent hydrocarbon group of any one of methyl group, ethyl group, vinyl group or phenyl group, and (m) is an integer of 100-10000), 0.5-30 pts.wt. of organohydrogen polysiloxane which is shown by formula II and contains a hydrogen atom (<=SiH) which is combined with two or more of silicon atoms in a molecule (R<2> represents any one atom of hydrogen atom, methyl group, ethyl group, and phenyl group or monovalent hydrocarbon group, and (n) is an integer of 10-1000) and a platinum catalyst is simultaneously extruded so as to heat and cure. |
