摘要 |
<p>An adhesive composition comprising a two-component system comprising A) at least one polyester urethane containing at least two isocyanate groups, which polyester urethane may be obtained by reaction of one or more polyesters 1 with aliphatic diisocyanates and reaction with one or more polyesters 2, wherein polyester 1 exhibits a number average molecular weight Mn in the range from 3,000 to 7,000 g/mol and polyester 2 exhibits a number average molecular weight Mn in the range from 700 to 2,000 g/mol and B) one or more branched polyesters with a number average molecular weight Mn in the range from 1,000 to 3,500 g/mol and optionally one or more conventional additives; the present invention provides a polyurethane-based adhesive composition which is suitable for the production of laminates for sterilizable packaging and exhibits a low residual content of highly volatile diisocyanates. The adhesive according to the invention ensures that no or only slight delamination of the film composites occurs even at elevated temperatures.</p> |
