  • Publication number: 20150218360
    Abstract: A binder formulation is provided including water, a first polymer, and a second polymer. The first polymer is preferred to be a poly(carboxylic acid) and the second polymer is preferred to be a co-polymer containing both carboxylic acid and hydrophobic monomers. The first polymer can be polymers such as poly(acrylic acid), poly(methacrylic acid), poly(maleic acid), or poly(itaconic) acid. The second polymer is preferred to be an alternating copolymer of a monomer of a carboxylic acid and a hydrophobic monomer such as styrene, isobutylene, or n-alkenes. These binder formulations are particularly useful in making granulated powders in powder metallurgy and additive manufacturing.

  • Publication number: 20120202723
    Abstract: Polyhydroxyl functional compounds that contain an all hydrocarbon backbone, wherein all of the hydroxyl groups are bonded to a primary carbon atom, are prepared through the reaction of an alpha, omega-terminal diol having a total of from about 6 to about 42 carbon atoms terminated with a mono-ol having a total of from about 4 to about 42 carbon atoms. The polyols can be used as additives in hydrocarbon oils, drilling fluids, industrial and automotive lubricating fluids, dispersants, engine lubricants, greases, coatings, adhesives, and also in magnetorheological fluids to improve various properties such as dispersion, wear protection, reduction of friction, high temperature stability, and improved aging.

  • Publication number: 20080312110
    Abstract: A magnetorheological (MR) fluid comprising a glycol-based carrier fluid, a magnetizeable particle, and an inorganic clay. The MR fluid is particularly suitable for use in devices that have materials incompatible with typical hydrocarbon-based MR fluids, for example in devices where natural rubber is in contact with the fluids as in automotive engine mounts. The fluid is substantially non-foaming, and an improvement over glycol fluids thickened with organoclays.
