Waterborne Polyurethane Dispersions for shoe adhesive WL-A104

The trend towards waterborne systems is also noticeable in the field of polyurethane adhesives. Apart from the ecological aspects,polyurethane dispersions have the advantage that,unlike non-aqueous PU systems.they can be applied in a way that combines high solids content with low viscosity irrespective of the molar mass.the wide adhesion range and the excellent stability values make the polyurethane dispersions the ideal raw material for a variety of demanding adhesive and primer applicatins.
