    摘要： The present invention is related to a structural member comprising a laminate and an adhesive where said adhesive is the reaction product of a) 100 parts by weight of at least one hydroxy functional material having a molecular weight of at least 300 and a hydroxy functionality of at least 2 which material is preferably selected from the group consisting of polyether polyols, polyester polyols, polyester amide polyols, and polycarbonate polyols, b) 2 to 20 parts by weight of an aliphatic, aromatic and/or cycloaliphatic diamine or triamine, and c) an organic isocyanate in an amount sufficient to render the isocyanate index between about 70 and about 150, wherein said component c) is not pre-reacted with any of the component a) and b). In a preferred embodiment, there is included upto 50 parts by weight of component d) which is an aliphatic polyol having a functionality of at least 2 and a molecular weight of below 300. The invention also relates to a process for bonding substrates especially laminates which comprises applying a reaction mixture forming said adhesive preferably with aid of a counter current mixing device forming non-sagging beads of said reaction mixture.
