Abstract

El propósito de la presente invención es proporcionar un agente aglutinante orgánico curable con uretano con el cual un molde que tiene resistencia mejorada al deterioro en resistencia debido a la humedad se puede obtener ventajosamente, y también proporciona un agente aglutinante orgánico curable con uretano para un molde con el cual la resistencia del molde debido a que se deja después de la conformación se puede mejorar de manera eficaz. El agente aglutinante orgánico curable con uretano se usa para conformar un molde basado en uretano y se configura para incluir, como componentes constituyentes, un compuesto de poliol, un compuesto de poliisocianato, y adicionalmente un producto de reacción de un compuesto de silano básico y un ácido o un haluro del mismo.
