  • Aqueous hybrid bonding composition and process
    Publication number: 20030022979
    Abstract: A process for making an article contacted with a bonding agent that is prepared by providing an admixture including a latex and a polyol present in an amount of less than 20 wt. % of the admixture for providing hydroxyl functionality. The isocyanate is admixed with the latex/polyol admixture to form the bonding agent. A layer of the bonding agent is contacted with a substrate.

  • Packaging adhesive having low oxygen barrier properties
    Patent number: 5763527
    Abstract: A two-part laminating adhesive is provided which joins two sheets of polymeric material, which adhesive, in cured form, provides substantially no contribution to the oxygen barrier properties of the laminate. The first part is a mixture of a polyol A), preferably a polyether, and a polymer B) formed from polymerization of .alpha.,.beta.-ethylenically unsaturated monomers, polymer B) preferably being formed in situ from monomers dissolved in polyol A). The second part is a multi-functional isocyanate, preferably an isocyanate-terminated urethane formed by reacting a poly-isocyanate monomer with a polyol.
