PURPOSE:The titled composition curable at normal temperature, having improved adhesiveness at extremely low temperature, obtained by blending a specific epoxy resin mixed system with a specified curing agent mixed system in a specific ratio, adding a specific amount of an inorganic fibrous substance to at least one mixed system. CONSTITUTION:An epoxy resin mixed system consisting essentially of a nonalicyclic epoxy resin (e.g., glycidyl ether resin, etc.) having >=1.7 epoxy group per molecule on an average and about 70-1,000 epoxy equivalent is blended with a curing agent mixed system consisting essentially of 15-95wt% polyether polyamine such as polyoxyethyleneamine, etc. and 85-5wt% liquid acrylonitrile- butadiene copolymer having >=1.7 primary and secondary amino groups per molecule on an average in such a way that an amount of active hydrogen in amino group of the curing agent mixed system is 0.2-2.0 equivalent based on epoxy group, and at least one of the blended systems is blended with 10-65wt% inorganic fibrous material (e.g., asbestos, etc.) to give the desired epoxy resin composition.
