A curable composition that includes an amorphous, peroxide-curable fluoropolymer having a first solubility parameter, a solvent having a second solubility parameter, and a peroxide. The amorphous, peroxide-curable fluoropolymer is present from 60 percent to 97.5 percent by weight versus the weight of the curable composition, and the solvent is present from 1 percent to 39 percent by weight versus the weight of the curable composition. The absolute value of the first solubility parameter minus the second solubility parameter is less than or equal to 8.2 (MPa)1/2. The solvent may have a solubility parameter in a range from 9.6 (MPa)1/2 to 26 (MPa)1/2. Methods of making a cured fluoroelastomer from the curable composition are also disclosed.

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.

A reflective particulate composition includes a particulate mixture that includes a particulate substrate, a hardness enhancer and a pigment. The reflective particulate substrate has a hydrophobic coating on the particulate mixture. The composition may have a solar reflectance of 70% or greater. The pigment may include a clay, and the particulate substrate may include a feldspar. A method of making the composition may include mixing the particulate substrate, the hardness enhancer, and the pigment to forma particulate mixture, heat treating the particulate mixture, and coating the heat treated mixture with the hydrophobic coating.
摘要:
The invention relates to a coating composition for making a porous inorganic oxide coating layer on a substrate, the composition comprising an inorganic oxide precursor as binder, a solvent, and a synthetic polyampholyte as pore forming agent. The size of the pores in the coating can be advantageously controlled by the comonomer composition of the polyampholyte, and/or by selecting conditions like temperature, pH, salt concentration, and solvent composition when making the composition. The invention also relates to a method of making such coating composition, to a process of applying a coating on a substrate using such composition, and to such coated substrate showing a specific combination of optical and mechanical properties.
