ROBUST ADHESIVES FOR LAMINATING FLEXIBLE PACKAGING MATERIAL |
摘要 |
A robust, two component adhesive for laminating flexible packaging material comprising a mixture of Component A and Component B. Component A comprises an isocyanate-functionalized compound. Component B comprises a mixture of a high functionality polyol containing at least four hydroxyl groups per molecule with at least two primary OH groups on the molecule and two secondary OH groups on the molecule and a trifunctional polyol containing three OH groups on the molecule. Component B can contain a difunctional polyol containing two OH groups on the molecule. The adhesive is robust and retains desirable properties when used at varying A:B mix ratios better than conventional laminating adhesives used at the same mix ratios.
