Superhydrophobic and oleophobic coatings with low VOC binder systems

A coating composition for the application of superhydrophobic, or superhydrophobic and oleophobic, coatings on surfaces comprising:

• a one-component waterborne polyurethane dispersion or suspension comprising one or more of a polyester urethane, a polyacrylic urethane and/or a polycarbonate urethane in water, or a water containing medium;
• about 5 to about 30% by weight of hydrophobic, or superhydrophobic and oleophobic, second particles comprising one or more siloxanes, and/or one or more alkyl, haloalkyl, fluoroalkyl, or perfluoroalkyl containing moieties;
• said composition optionally comprising up to about 26% by weight of third particles;
• wherein said coating composition comprises less than 0.3 pounds per gallon of volatile non-exempt organic compounds;
• wherein said coating composition optionally comprises first particles;
• and
• wherein the superhydrophobic coating resulting from the application of said composition to a surface retains its superhydrophobicity after 150-1,400 Taber abrasion cycles at a 1000 g load for a coating thickness range of 25-300 microns, and/or 100-2,500 Taber abrasion cycles at a 250 g load, using a CS10 wheel, as judged by the inability of more than 50% of the water droplets applied to the area of the coating subjected to said abrasion cycles to remain on the surface when the planar surface is inclined at 3 degrees.
