Abstract:
Novel aqueous lubricant dispersions contain at least one rare earth halide, e.g., cerium trifluoride, and at least one polymeric dispersing agent therefor, such at least one dispersing agent including: (a) a copolymer of an ethylenically unsaturated carboxylic acid or derivative thereof with an alpha -olefin comonomer and/or a vinyl comonomer; (b) a homopolymer or copolymer of an ethylenically unsaturated carboxylic acid or derivative thereof; (c) a copolymer of at least one ethylenically unsaturated carboxylic acid and at least one ethylenically unsaturated sulfonic acid comonomer; and/or (d) a polymer of an alkylene oxide of an (arylalkyl)phenol, or phosphated or sulfated derivative thereof.
Abstract:
Boron soap compounds are provided. Lubricating grease compositions are provided. The lubricating grease compositions include a lubricating oil and at least one boron soap compound. The lubricating grease compositions can optionally include one or more additive.
Abstract:
Provided are microalgal compositions and methods for their use. The microalgal compositions include lubricants that find use in industrial and other applications.
Abstract:
A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.
Abstract:
A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.
Abstract:
Die Erfindung betrifft ein Gleitlager (1) umfassend eine metallische Stützschicht (2), eine Lagermetallschicht (3) und eine Laufschicht (4) hergestellt aus einem Gleitlack, wobei die metallische Lagermetallschicht (3) zwischen der Stützschicht (2) und der Laufschicht (4) aus dem Gleitlack angeordnet ist, und wobei weiter die Laufschicht (4) eine Matrix aus einem Polyimid aufweist, in der zumindest ein plättchenförmiger Festschmierstoff enthalten ist, wobei in der Polyamidimid-Matrix zusätzlich Fasern enthalten sind.
Abstract:
A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.
