[Problem] The present invention provides a hydrosilylation reactive composition capable of maintaining the pot life of the composition, and a method for producing a semi-cured product and a cured product using the same, and which exhibits a distinct Hardenability, and molecular design by controlling the reaction of MH unit/ DH unit is possible. [Solution] The present invention is a composition comprising: (A) at least one molecule having an aliphatic unsaturated bond in one molecule, and a method for performing a hydrosilylation reaction using the same at a two-stage temperature. (B) a compound containing in one molecule at least two hydrogen atoms bonded to silicon atoms; (C) a first hydrosilylation catalyst; and (D) a second hydrosilylation catalyst, which passes the softening point The thermoplastic resin in the temperature range of 50 to 200°C microencapsulates the compound described as the component (C) above, and exhibits activity at a temperature higher than that of the component (C). |
