Solid-state branching and/or crosslinking of aliphatic polyamide or polyester articles is achieved using a topical approach. A surface of the article is coated with a composition that includes a polyene and a free radical initiator. The article and applied coating are then heated to induce branching and/or crosslinking in the polyamide or polyester. This is performed below the crystalline melting temperature of the polyamide or polyester, or in the case of a fabric, below the melting temperature of the fibers in the fabric. Fabrics treated in this manner exhibit reduced or even no dripping in vertical flame tests.

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.
