ABSTRACT:
Novel aqueous polyurethane dispersions and adhesive films formed therefrom are provided. The aqueous polyurethane dispersions are provided in solvent-free systems of a prepolymer comprising at least one polyether or polyester polyol, a mixture of MDI isomers, and a diol. The adhesive films from such dispersions can be heat-activated for bonding, lamination, and adhesion of textile fabrics, including stretch fabrics.
