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°C or greater.
La présente invention concerne une composition solide à température ambiante, particulièrement stable au stockage, convenant particulièrement comme additif pour des résines époxy. L'invention concerne également l'élaboration de la composition. Cette composition est réalisée à partir d'un agent de couplage silané basique et d'un sel d'acide carboxylique. Pour préparer cette composition, on fait réagir avec un acide carboxylique un agent de couplage silané basique, ce qui donne le sel correspondant à l'agent de couplage et à l'acide. On mélange ensuite, en les chauffant, le sel obtenu et un composé à forte affinité pour l'agent de couplage ou l'acide, le point de ramollissement ou de fusion de ce composé n'étant pas inférieur à 40 DEG C.
