The performance of coatings prepared from one-component waterborne polyurethane dispersions is generally inferior to one- or two-component cross-linked films in terms of chemical resistance and mechanical durability, particularly in soft-touch coatings. By incorporation of polyester acrylates into the backbone of the polymer we can impart a new level of chemical and mechanical resistance while maintaining the desired soft feel. In addition, the cure time of these films is greatly reduce to as little as three minutes (elevated flash off temperature, UV cure). More so than solvent-borne and/or acrylic monomer containing systems, UV-Curable PUDs are environmentally friendly since they are reduced in water.
