摘要:
A two component laminating adhesive is provided, wherein one component contains at least one isocyanate-functionalized compound and the other component contains one or more 1,4:3,6 dianhydrohexitols. A laminate may be formed by combining the two components to provide an adhesive and then using the adhesive to adhere one polymeric film or metallic foil to another polymeric film or metallic foil. The adhesive layer between the film and/or foil layers of the laminate is then cured. The adhesives exhibit faster green strength development and higher final bond strength as compared to conventional two component laminating adhesives not containing any 1,4:3,6 dianhydrohexitol as a coreactant.
