Abstract
Se describe un método para preparar una composicion de agente de curado para resinas epoxi. En este método se convierte en aducto un compuesto de imidazol con resina epoxi en presencia de agua. Este procedimiento es particularmente adecuado para una produccion por lotes a gran escala, y las composiciones de resina epoxi que contienen esos agentes de curado muestran una mejor estabilidad durante el almacenamiento.
