ABSTRACT:
A method for producing a two-component bonding agent composition. The method uses a mixture whose first component contains: (i) 50 to 98 wt % of a hydroxy-terminated polyester having a hydroxyl number from 50 to 350 and hydroxyl functionality from 2 to 3; (ii) 1 to 30 wt % of an epoxy resin having an epoxy equivalent weight from 500 to 4000; and (iii) 1 to 20 wt % of an organic alkoxysilane containing C1-C4alkoxy groups. The second component contains a multi-functional isocyanate having an isocyanate functionality from 1.8 to 4; wherein the second component is present relative to the first component at a molar ratio of NCO/OH groups of 0.9:1 to 3:1.
