Abstract: The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.

Abstract: Embodiments of organic peroxide formulations provide longer scorch time protection and require fewer additives. The peroxide formulations may include, for example, at least one organic peroxide, at least one nitroxide-containing compound (e.g., 4-hydroxy-TEMPO), and at least one quinone-containing compound (e.g., mono-tert-butylhydroquinone). Embodiments of the present invention relate to organic peroxide compositions comprising scorch retarders. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.

Abstract: The present invention relates to imidazole and/or its derivative as polyurethane or polyisocyanurate foam catalyst in the presence of Low Global Warming Potential (GWP) halogenated olefinic blowing agents, such as the hydrochlorofluoroolefin (HCFO) HCFO-1233zd. More particularly, the present invention relates to catalyst compositions comprising imidazole and/or its derivative. The present invention further relates to the stable pre-blend formulations and resulting polyurethane or polyisocyanurate foams. A method for stabilizing thermosetting foam blends comprises combining: (a) a polyisocyanate and, optionally, isocyanate compatible raw materials; and (b) a polyol pre-mix composition comprising a halogenated olefinic blowing agent, a polyol, a surfactant, and a catalyst, wherein the catalyst comprises substituted imidazole having C2 or greater substitutions at the N1 nitrogen and/or its derivative. The resultant polyurethane or polyisocyanurate foams have uniform cell structure with little or no foam collapse.

Abstract: A plastic container configured to store and/or transport liquids, including chemicals such as organic peroxide, includes a top portion, a base portion, and a sidewall that extends between the top portion and the base portion. The top portion has a vent spout and a main spout. The top portion also has a front surface portion having a slanted face and a lip that extends radially from the main spout away from the slanted face. Additionally, the top portion has an integrated handle that defines a maximum handle length that is approximately half of the maximum container length. The base portion has an interior surface and an exterior surface. The exterior surface defines a handle recess.

Abstract: Fluorinated olefins are produced in a reductive coupling reaction by contacting a first reactant with a second reactant in the gas phase under an inert atmosphere at a temperature of at least 500 C. The first reactant may be, for example, a hydrofluorocarbon containing one or two carbon atoms, while the second reactant may be, for example, a two to four carbon hydrohalocarbon (e.g., a hydrofluorocarbon) or hydrocarbon.

Abstract: Encapsulated peroxide particles inhibit skin inflammation. A method of encapsulating a solid peroxide comprises dispersing solid peroxide particles (e.g., benzoyl peroxide) in an aqueous dispersion of fatty acid salt to form a peroxide/fatty acid salt dispersion, wherein the peroxide particles have a mean particle size (D50) of 10 μm or less; and subsequently encapsulating the solid peroxide particles by reacting the one or more monovalent fatty acid salts with one or more multivalent salts of calcium, magnesium, aluminum, silver, and/or zinc, thereby forming encapsulated peroxide particles.

Abstract: The invention relates to an aqueous fluoropolymer hybrid composition having superior weathering resistance while maintaining excellent mechanical properties in coatings, paints, caulks and adhesives. The composition is comprised of: a) a vinylidene fluoride polymer, such as KYNAR® polymers from Arkema, b) a first vinyl polymer immiscible with the vinylidene fluoride polymer and having a Tg of less than 0° C., and c) a second vinyl polymer of a different composition, also having a Tg of less than 0° C., and containing groups capable of crosslinking. The invention also relates to waterborne coatings or paints containing the aqueous fluoropolymer hybrid composition, and an article, object, or structure coated with the fluoropolymer hybrid composition on at least one surface, either in a factory or in the field, to confer protection and decorative properties. Free films made from the waterborne compositions of the invention have a dynamic mechanical analysis loss tangent, tan (δ), of greater than 0.22 at a temperature of 0° C.

Abstract: Methods of synthesizing fluorosilanes containing cyano-substituted alkyl groups are provided. For example, 3-cyanopropyldimethylfluorosilane may be produced by reacting tetramethyldisiloxane and boron trifluoride to obtain fluorodimethylsilane and then reacting the fluorodimethylsilane with allyl cyanide, in the presence of a hydrosilylation catalyst.

Abstract: A process for recovering (meth)acrylic acid includes distilling a mixture comprising (meth)acrylic acid in a finishing column at less than atmospheric pressure to produce a finishing column overhead stream and a finishing column bottoms stream. An overhead aspirating direct contact condenser system at least partially condenses the finishing column overhead stream to form a finishing column overhead condensate and an overhead non-condensables vent stream. A finishing column vapor-phase side draw may also be recovered. An aspirating direct contact condenser system may be used to at least partially condense the vapor-phase side draw.
