Abstract

The present invention relates to a process for bonding two or more wood substrates by using as the adhesive isocyanate-terminated prepolymers having an isocyanate content of 8 to 20 wt. % and containing the reaction product of a) at least one organic polyisocyanate with b) at least one organic polyhydroxyl compound containing the reaction products of i) organic polyisocyanates with ii) polyamines, hydrazines and/or hydrazides having primary and/or secondary amino groups dispersed in a iii) polyethers having at least two hydroxyl groups and a number average molecular weight of 500 to 12,000; and, the present invention also relates to the bonded substrates obtained by this process.
