[Problem] To provide an aqueous coating agent composition (in particular, an aqueous coating composition for lubricating films that contains a solid lubricant) which as a whole is excellent in terms of flowability, applicability, and storage stability and which is capable of forming satisfactory and smooth coating films effective in stick-slip inhibition. [Solution] The problem can be solved with an aqueous coating agent composition which comprises (A) a curable resin in an aqueous emulsion form, (B) a surfactant, (C) solid particles, (D) one or more nitrogenous heterocyclic compounds, (E) a film-forming silicone in an aqueous emulsion form, and (F) water. In particular, it is preferable that the (C) component comprise a solid lubricant. In view of the environmental regulations, it is especially preferable that the (D) component be 1,3-dimethyl-2-imidazolidinone.

摘要:
The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated and functionalized. The dispersant substances include compositions including a copolymer of two different conjugated dienes, a copolymer of a p-alkylstyrene and a conjugated diene, or a homopolymer of a conjugated diene. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.

The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.

Disclosed are bearing liners (10) comprising a supporting fabric (1) and a shaped body of low-friction polymeric resin (2) supported by the fabric. At least that portion of the shaped body in contact with the load undergoes cold flow upon the application of the load to the bearing liner. It is preferred that the amount of cold flow exhibited by the shaped body is sufficient to increase by 100 % or more the area of surface contact between the load and the shaped body. According to one preferred embodiment, the braided fabric (1) comprises polyester yarn and the low-friction polymeric resin (2) comprises fluorocarbon polymer monofilament.
摘要:
A silicone grease composition comprising a vinyl-containing organopolysiloxane fluid, platinum or a platinum compound such as chloroplatinic acid and a thickening agent such as a finely divided silica filler. By virtue of this unique formulation, the silicone grease composition is self-extinguishable when it is set on fire so that it is useful as a filling material for electric cables.
摘要:
Die Erfindung betrifft ein Verfahren zum Stabilisieren von in den endständigen Einheiten Triorganosiloxy-Gruppen enthaltenden Organopolysiloxanölen, in dem man die genannten Organopolysiloxanöle mit Verbindungen der Formel
