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: (R&#x2212;L&#x2212;P)A Ris a fluorinated group; L is independently an organic divalent linking group; P is a catenary, divalent heteroatom-containing carbonyl moiety, such as &#x2014;C(O)O&#x2014;; 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.

Articles subject to ice formation comprising a repellent surface

Presently described are components of a spray application system. At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface.

Spray application system components comprising a repellent surface and methods

Presently describes are articles, such as liquid reservoirs, comprising a liquid repellent surface. The liquid repellent surface comprises a surface layer comprising a silane or siloxane material, wherein the liquid repellent surface is not a lubricant impregnated surface. In one embodiment, the liquid repellent surface (e.g. layer) comprise a silicone melt additive and a thermoplastic polymeric material component. In some embodiments, the article (e.g. liquid reservoir) comprise a thermoplastic polymeric material.

Liquid reservoirs and articles comprising a repellent surface comprising a siloxane material

Articles subject to ice formation during normal use, are described comprising a repellent surface such that the receding contact angle of the surface with water ranges from (90) degrees to (135) degrees wherein the repellent surface comprises a siloxane material. In one embodiment, the repellent surface further comprises a non-fluorinated organic polymeric binder. In another embodiment, the repellent surface comprises a thermally processable polymer and a siloxane material melt additive. 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.

Articles subject to ice formation comprising a repellent surface comprising a siloxane material

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 prefer-ably a compound having the formula: (R-L-P)A Ris a fluorinated group; L is independently an organic divalent linking group; P is a catenary, divalent heteroatom-containing carbonyl moiety, such as &#x2014;C(O)O&#x2014;; 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.

Some aspects of the present disclosure feature a sensing device comprising a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The environmental change receptor is disposed on a surface of the resonator. The mass of the environmental change receptor is changed in response to a change in environment. The resonant frequency of the sensing device shifts in response to the mass change of the environmental change receptor.

Magneto-mechanical resonator sensor with pre-disposed mass

Retroreflective articles include transparent microspheres () protruding from a bead bond layer (), with reflective metal layers () coated on a portion of the transparent microspheres. Retroreflective articles with anti-staining properties have bead bond layers that contain one or more corrosion inhibiting compounds. At least a portion of the one or more corrosion inhibiting compounds migrates through the reflective metal layer to passivate the exposed metal surface of the reflective metal layer.

Stain resistant retroreflective articles
