ADHESIVE USEFUL FOR FILM LAMINATING APPLICATIONS

摘要

An adhesive that is capable of being cured in at least two stages is prepared by combining at least one isocyanate-functionalized polyurethane prepolymer, at least one hardener, and at least one (meth)acrylate-functionalized compound selected from the group consisting of polyester (meth)acrylates containing hydroxyl functional groups, adducts of epoxy-functionalized poly(meth)acrylic resins and (meth)acrylic acids, polybutadiene (meth)acrylates, and polyoxyalkylene ether mono(meth)acrylates. Such adhesives are particularly useful as two part laminating adhesives in the assembly of flexible laminates.
