Abstract
The disclosure relates to a thermoset omniphobic composition with favorable dirt repellency and water resistance properties. The composition can be used as a protective coating on a substrate. Such coatings, when contacted with soil, dirt, dust, etc., remain clean and transparent. The omniphobic composition generally includes a thermoset polymer, an omniphobic polymer, and a filler or nanofiller. The thermoset polymer can be a crosslinked acrylate or other vinyl polymer. The omniphobic polymer can include fluorocarbon and/or siloxane groups for improving water resistance. The nanofiller can include nanosilica and/or nanoclay. The thermoset polymer and the omniphobic polymer together form a matrix for the filler as a dispersed phase throughout the matrix. A coated substrate with the thermoset omniphobic composition thereon exhibits favorable water contact and sliding angles as well as favorable transparency values in dirt accumulation tests.
