Abstract: Articles subject to ice formation during normal use are described. The article comprises a repellent surface such that the receding contact angle of the surface with water ranges from 90 degrees to 135 degrees. The repellent surface comprises a fluorochemical material, typically in combination with a non-fluorinated organic polymeric binder. The fluorochemical material is preferably a compound having the formula: (Rf?L?P)nA Rf is a fluorinated group; L is independently an organic divalent linking group; P is a catenary, divalent heteroatom-containing carbonyl moiety, such as —C(O)O—; A is hydrocarbon moiety; and n typically ranges from 1 to 3; also described are methods of making an article comprising providing an article subject to ice formation during normal use and providing a liquid repellent surface, as described herein, on at least a portion of the article.

Abstract: Articles subject to ice formation during normal use are described. The article comprises a repellent surface such that the receding contact angle of the surface with water ranges from 90 degrees to 135 degrees. The repellent surface comprises a fluoro chemical material, typically in combination with a non-fluorinated organic polymeric binder. The fluorochemical material is preferably a compound having the formula: (Rf-L-P)nA Rf is a fluorinated group; L is independently an organic divalent linking group; P is a catenary, divalent heteroatom-containing carbonyl moiety, such as —C(0)0-; A is hydrocarbon moiety; and n typically ranges from 1 to 3. Also described are methods of making an article comprising providing an article subject to ice formation during normal use and providing a liquid repellent surface, as described herein, on at least a portion of the article.

Abstract: The present invention is directed to an article comprising a backing, the backing comprising a first major surface and a second major surface, wherein the first major surface comprises a microstructured surface comprising microstructure elements; and a low-flow adhesive layer opposite the microstructured surface. Additionally, the present invention is directed to multi-layer embodiments that are linerless.
