Patent ID: 11274227

Abstract:
A novel omniphobic surface coating is disclosed that provides both high oil-repellency and high-water repellency to the coated surface. The coating may contain perfluoropolyether (PFPE) or a similar fluorinated or perfluorinated polymer, as well as a hardener and a catalyst. One or more surfactants or viscosifiers may also be added. Further, the coating may contain one or more functional additives, including, but not limited to, coloring agents, anti-corrosive agents, anti-fouling agents, water-repellent agents, and/or oil-repellent agents. Methods for formulating the novel omniphobic surface coating are also described. Such methods include preparing a first part of the coating, which may contain, at minimum, a polymer such as PFPE or a similar fluorinated or perfluorinated polymer, and a suitable solvent; preparing a second part of the coating, which is a water-free system that may contain, at minimum, a hardener and a catalyst; and combining the first part and the second part together.
