Abstract

Un método para unir adhesivamente o sellar dos sustratos, el cual comprende: (1) aplicar a aproximadamente 50 degree C sobre un sustrato una composicion adhesiva que funde con calor de uretano, curable con la humedad, sin solvente, que comprende el producto de la reaccion del prepolímero poliisocianato de (a) un poliol y (b) poliisocianato; (2) poner contacto el adhesivo colocado cobre el sustrato, de tal manera que la union por cochura se forma, y (3) exponer la union adhesiva a la humedad ambiental provocando una reaccion de reticulacion dentro del adhesivo, por lo que forma una union curada por la humedad. La mejora está caracterizada por que el prepolímero poliisocianato se prepara por la reaccion de un poliisocianato con una funcionalidad de por lo menos dos con un poliol con una funcionalidad de por lo menos 2, el producto de la reaccion comprende por lo menos 905 por peso del prepolímero "perfecto" y menos de 2% por peso del monomero isocianato sin reaccionar y el prepolímero que tiene una funcionalidad de NCO libre en el rango de 0.2 a 8% por peso.
