Abstract

Un procedimiento "de endurecimiento en frío" permite la formación de mayores piezas fundidas de metales, proporcionando más tiempo de trabajo, en el rango de aproximadamente 45 a aproximadamente 60 minutos. Esto se logra utilizando un catalizador de curado líquido que es una piridina, sustituida en la segunda o tercera posición con una humedad que tiene un peso molecular en el rango de aproximadamente 30 a aproximadamente 100 g/mol. Los ejemplos del catalizador de curado líquido incluyen 2-etanolpiridina, 3-cloropiridina y 2-metoxipiridina. Cuando se combina con un precursor aglutinante de poliuretano de dos partes y un agregado de fundición, el catalizador de curado líquido no proporciona únicamente más tiempo de trabajo, sino también un tiempo de despojo que es menor a aproximadamente 167% del tiempo de trabajo, según se midió del punto de activación de los precursores de poliuretano mezclándolos en presencia del catalizador de curado.
