Abstract
Double fluid hardening resion compositions are hereby offered which contain a hardening resin base composed of bisphenol A epoxy resion and paraoxybenzoic glycydylester-ether epoxy resin and a hardening agent constituted by a complex of a polybasic carboxylic ester derived from an alcohol having a cyclic ether linkage in its molecule and boron trifluoride. These compositions are capable of very quick setting of resin and their hardened form possesses excellent physical properties, so that they are useful for urgent repairs of pipings, tanks, etc.
