Title:
LIQUID EPOXY RESIN COMPOSITION FOR SEALING AND CURED MATERIAL THEREOF
Document Type and Number:
Japanese Patent JP3633674
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a sealing epoxy resin composition having low viscosity and excellent in heat and moisture resistances by using an epoxy resin, a specified allylated phenol resin and a cure accelerator as the constituents.
SOLUTION: This composition is obtained by blending an epoxy resin with an allylated phenol resin comprising an allylated novolak phenol resin which contains at most 10 area% allylated phenol aralkyl resin and/or binuclear components, in which trinuclear components account for at least 50 area% of the remaining part excluding the binuclear components and in which the total of the trinuclear component content and the tetranuclear component content is at least 75 area% in an amount sufficient to provide a stoichiometric ratio of the hydroxy groups to the epoxy groups of the epoxy resin of (0.2 to 2):1 and at least one cure accelerator selected from the group consisting of organophosphine compounds and nitrogen-containing cyclic compounds in an amount of 0.01-10 pts.wt. based on 100 pts.wt. epoxy resin.
