LOW ELASTIC RESIN COMPOSITION, LOW ELASTIC RESIN HARDENED MATERIAL AND ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To obtain a low elastic resin composition capable of realizing the compatibility of low elasticity after hardening and environmental resistance and a low elastic resin hardened material obtained by hardening the composition, and to provide an electronic equipment using the hardened material. SOLUTION: This composition composed of a main component A comprising a polyglycidyl ether-type epoxy, a main component B comprising a polyglycidyl ether-type epoxy, and a hardener in an amount of 1.5-15 times by equivalent in terms of an active hydrogen based on the total epoxy equivalent of the main components A and B and/or a hardening catalyst of 50-300 mol.% based on the total epoxy equivalent of the main components A and B. The hardening reactions not only of the main component A but also of the main component B are completed by adding a large excess of the hardener or the hardening catalyst.
