Aqueous two-component dispersion adhesive

摘要

An aqueous two-component aqueous dispersion adhesives, including in particular polyether-polyurethane polymers and ethylene vinyl acetate copolymers (EVA) having a glass transition temperature of greater than 0° C. The dispersion adhesives are optimally suited for use as contact adhesives, and for gluing plastic membranes. It has been demonstrated that the adhesives or the adhesive composite items produced therewith are characterized by an exceptionally low plasticizer absorption behavior, and contact adhesion. The good heat resistance and good bonding to various bases are also advantageous.
