There are provided a composition for functioning as an effective additive for epoxy resin that is solid at room temperature and has high storage stability, and a method thereof. The composition of the present invention is a basic silane coupling agent organic carboxylate composition obtained by first synthesizing an organic carboxylate of a basic silane coupling agent by reacting a basic silane coupling agent and an organic carboxylic acid, and subsequently heating and mixing the organic carboxylate of the basic silane coupling agent with a compound exhibiting good affinity for the basic silane coupling agent or organic carboxylic acid and having a softening point or melting point of 40&#xb0; C. or greater.

A water-based metal surface treatment agent for the surface treatment of metals including aluminum products such as pre-coated aluminum sheets gives excellent coating film adhesion, flexibility and acid resistance. The water-based metal surface treatment agent contains the following components (1) to (3):

Water-based metal surface treatment agent

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&#xb0; 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.
