Abstract

La presente descripción proporciona un método para reducir el contenido de aldehídos en un catalizador del amina al tratar el catalizador de amina con un agente para tratamiento seleccionado de una urea cíclica sustituida con al menos un grupo reactivo de isocianato, un depurador de radicales libres y una mezcla de los mismos. El catalizador de amina tratado luego se puede utilizar en la producción de materiales de poliuretano los cuales exhiben emisiones reducidas de aldehído.
