Abstract
This composition comprises: (A) one or both of (i) and (ii), said (i) being polysiloxane (1) having a viscosity of 50-10,000,000 mPa·s,RRSiO(RSiO)SiRR (1),and said (ii) being polysiloxane (2),(RSiO)(RRSiO)(SiO) (2); (A is an alicyclic epoxy group represented by formula (6)), wherein the ratio of the total number of SiH's to the number of unsaturated bonds between (D) and the alkenyl of (A) is 0.8-1.5, said composition is rapidly cured at room temperature after mixing to exhibit adhesiveness to a substrate such as a metal or resin, and even after the cured product following adhesion is exposed to a high-temperature and high-humidity environment, the adhesiveness to the substrate does not deteriorate.
