Abstract: The disclosure relates to a thermoset omniphobic composition, which includes a thermoset polymer with first, second, and third backbone segments, urethane groups linking the first and third backbone segments, and urea groups linking the first and second backbone segments. The first, second, and third backbone segments generally correspond to urethane or urea reaction products of polyisocyanate(s), amine-functional hydrophobic polymer(s), and polyol(s), respectively. The thermoset omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The thermoset omniphobic composition can be used as a coating on any of a variety of substrates to provide omniphobic properties to a surface of the substrate. Such omniphobic coatings can be scratch resistant, ink/paint resistant, dirt-repellent, and optically clear. The thermoset omniphobic composition can be applied by different coating methods including cast, spin, roll, spray and dip coating methods.

Abstract: The disclosure relates to methods for forming an omniphobic thermoset composition, such as an omniphobic polyurethane or epoxy composition. First and second thermosetting components are applied to a substrate and partially cured. A functionalized hydrophobic/oleophobic/omniphobic polymer which is reactive with at least the first thermosetting component is then applied to the coated substrate, which is then further cured to form a thermoset omniphobic coating on the substrate. The thermoset omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The thermoset omniphobic composition can be used as a coating on any of a variety of substrates to provide omniphobic properties to a surface of the substrate. Such omniphobic coatings can be scratch resistant, ink/paint resistant, and optically clear. The thermoset omniphobic composition can be applied by different coating methods including cast, spin, roll, spray and dip coating methods.
