摘要： Conventionally, there was a need to add a large amount of electroconductive particles for improving conductivity, but when the electroconductive particles were added too much, initial viscosity was increased, and at the same time, it was difficult to stabilize preservation stability. However, conductivity can be improved without adding a large amount of the electroconductive particles by selecting a monomer, and at the same time, preservation stability can be stabilized by using certain electroconductive particles. A thermocurable electroconductive adhesive including components (A) to (D): component (A): an oligomer having a (meth)acryl group; component (B): a monomer having one methacryl group in a molecule; component (C): an organic peroxide having a specific structure; and component (D): electroconductive particles which are surface-treated with a stearic acid.

摘要： In the (meth)acrylic resin composition of the present invention, when a sealed container is used, it is possible to achieve both storage stability in an atmosphere at 25° C. and low temperature curability in an atmosphere at 60 to 140° C., and further, properties thereof can be exhibited even in an electroconductive adhesive including electroconductive particles. The present invention is a (meth)acrylic resin composition including the following components (A) to (C): component (A): a urethane modified oligomer having a (meth)acrylic group, component (B): a monomer having a hydroxyl group and/or a carboxylic group and one (meth)acrylic group in a molecule in which a surface tension is 25 to 45 mN/m, and component (C): an organic peroxide having a specific structure.

摘要： Conventionally, when an adherend is nickel or the like, it has been difficult to realize an electroconductive adhesive that lowers connection resistance in various kinds of thermocurable curing resins. However, it is possible to provide an electroconductive adhesive, in the case where the adherend is nickel or the like, which reduces connection resistance in various kinds of thermocurable curing resins while simultaneously maintaining storage stability to have good handleability. The present description provides a thermocurable electroconductive adhesive including the following components (A) to (D): Component (A): a curable resin, Component (B): a thermal curing agent that cures Component (A), Component (C): an organometallic complex, and Component (D): electroconductive particles.
