The present invention provides an organic carboxylate composition that has long working life, cures epoxy resins, and improves adhesive properties, and also provides a method for producing the same. An organic carboxylate composition, obtained by heating and mixing a basic silane coupling agent and an amine compound with a softening point or melting point of 40° C. or greater together with an organic carboxylic acid; a method for producing the same; an additive for epoxy resin that contains this as the active ingredient thereof; and an epoxy resin composition containing the same. The basic silane coupling agent should preferably be a specific imidazole-group containing silane coupling agent, amino group-containing silane coupling agent, dialkylamino group-containing silane coupling agent, monomethylamino group-containing silane coupling agent, benzimidazole group-containing silane coupling agent, benzotriazole group-containing silane coupling agent, and pyridine ring-containing silane coupling agent.
本发明提供一种有着长工作寿命、能够固化环氧树脂并提高粘合性能的有机羧酸盐组合物,同时也提供了一种制备该组合物的方法。该有机羧酸盐组合物是通过将具有软化点或熔点大于40℃的胺化合物和碱性硅烷偶联剂与有机羧酸一起加热混合而得到的;本发明还提供了一种制备该组合物的方法、以及一种含有该组合物作为活性成分的环氧树脂添加剂和含有该组合物的环氧树脂组合物。碱性硅烷偶联剂应该优选为特定的咪唑基团含量的硅烷偶联剂、含氨基团的硅烷偶联剂、二烷基氨基团含量的硅烷偶联剂、单甲基氨基团含量的硅烷偶联剂、苯并咪唑基团含量的硅烷偶联剂、苯并三唑基团含量的硅烷偶联剂和吡啶环含量的硅烷偶联剂。
