Abstract

La invención se refiere a una composición de adhesivo de poliuretano que se cura con humedad de un componente que comprende un prepolímero funcional de isocianato que puede obtenerse haciendo reaccionar: (a)uno o más poliisocianatos que comprenden diisocianato de metildifenilo; y (b) una mezcla de polioles que comprende (b1) un diol a base de óxido de butileno lineal con dos grupos hidroxilo primarios; y (b2) un poliéter triol con tres grupos hidroxilo secundarios, en la que en el intervalo de desde el 55 hasta el 75 % de los grupos hidroxilo en una mezcla de polioles (b) son grupos hidroxilo de un diol a base de óxido de butileno (b1), en la que la razón equivalente entre grupos isocianato en (a) y grupos hidroxilo en (b) está en el intervalo de desde 3,5 hasta 7,0, en la que el contenido de grupos isocianato libres en la composición de adhesivo está en el intervalo de desde el 14hasta el 17 % en peso. La invención se refiere además a un método de unir una primera pieza de material a una segunda pieza de material usando tal composición de adhesivo y a un objeto que comprende una primera pieza de material y una segunda pieza de material unidas con tal composición de adhesivo, en particular a un producto de madera estructural.
