Assignee:

Dow Corning Corporation - Midland MI

International Classification:

C07C 51/42
C07C 51/47

US Classification:

562580

Abstract:

Embodiments of a method for removing vicinal diols from a lactic acid fermentation broth comprise the steps of contacting the lactic acid fermentation broth with functionalized silica comprising at least one hydrophobic ligand to facilitate binding of the vicinal diols to the hydrophobic ligand, and separating the contacted lactic acid fermentation broth from the functionalized silica to remove the vicinal diols.

Abstract:

This invention provides a single phase silicone acrylate formulation that resists phase separation and includes (A) at least one of a silicone, an acrylate, and combinations thereof. The single phase silicone acrylate formulation also includes (B) a silicone acrylate hybrid compatibilizing agent including silicone functionality and (meth)acrylate functionality and that is the reaction product of a silicon-containing pressure sensitive adhesive composition, a (meth)acrylate, and an initiator. A method of minimizing phase separation of the single phase silicone acrylate formulation includes the step of combining (A) and (B) to form the single phase silicone acrylate formulation.

Appl. No.:

7/790906

Inventors:

Chana W. Evans - Saginaw MI
Anthony Revis - Freeland MI

Assignee:

Dow Corning Corporation - Midland MI

International Classification:

C08L 7500

US Classification:

524 94

Abstract:

This invention relates to radiation curable abrasion resistant coatings for solid substrates which are tintable. The compositions of the present invention contain a quaternary ammonium salt as a tintability enhancing compound. The cured coatings of this invention simultaneously resist abrasion and provide superior tintability.

Assignee:

Dow Corning Corporation - Midland MI

International Classification:

C08F 246
C08F 2004

US Classification:

522 84

Abstract:

A radiation curable protective coating composition is disclosed which contains at least one multifunctional acrylate or methacrylate monomer and colloidal silica dispersed in water or an organic solvent/water mixture. When applied to a substrate and radiation cured, the composition forms a transparent abrasion resistant, weather resistant, ultraviolet light resistant, coating firmly held thereon.

Assignee:

Dow Corning Corporation - Midland MI

International Classification:

C08L 8305

US Classification:

523203

Abstract:

The present invention is a heat curable polyorganosiloxane composition comprising (A) a first polydiorganosiloxane having two diorganoalkenylsiloxy terminal groups per molecule and a total concentration of unsaturated hydrocarbon radicals of 0. 118 to 0. 156 mole percent; (B) a second polydiorganosiloxane having two diorganoalkenysiloxy terminal groups per molecule, and no detectable concentration of pendant unsaturated hydrocarbon radicals; (C) a third polydiorganosiloxane having two diorganoalkenysiloxy terminal groups per molecule and a total concentration of unsaturated hydrocarbon radicals of 1. 37 to 2. 24 mole percent; wherein the weight ratio of polydiorganoiloxanes (A), (B), and (C) satisfy the relationship (C)/(A+B)=0. 0379 to 0. 1071 and A/B=1. 460 to 2. 115; (D) a crosslinker containing silicone-hydrogen bonds, wherein the ratio of silicone-hydrogen bonds to the total ethylenically unsaturated hydrocarbon radicals present on the polydiorganosilanes (A), (B), and (C) is from 1. 00 to 2.
