DESCRIZIONE
The invention relates to a superhydrophobic coating composition containing a polyurethane; a fluoropolymer; a nanofiller; and an organic solvent. The polyurethane to fluoropolymer are present in a weight ratio from about 1:2 to about 15:1. Coated substrate having at least a portion of one surface coated with a hydrophobic coating using the superhydrophobic coating composition are disclosed as are methods for forming a superhydrophobic coating on a substrate. The invention also relates to a method of forming a superhydrophobic coating on a surface of a substrate by spray casting a superhydrophobic coating composition onto a surface of a substrate to form a coating using an ultrasonic nozzle or at an air pressure of about 20 to about 60 psi and from a height of about 3 to about 12 inches above the surface to form a coating, and curing the coating.
