Abstract:
A lubricant composition useful for hot plastic working of metal material comprises 100 parts by weight of graphite particles and 2 to 100 parts by weight of particles of at least one metal oxide selected from oxides of Sn, Pb, Zn, Ca, Cu and Al and having an average size of 0.01 to 20.0 µm.
Abstract:
Thin impermeable, surface hardened, corrosion-resistant, durable, dry lubricant surface finishes are provided as well as surface finished products and methods for the production thereof. The surface finishes comprise particulate mixtures of sulfur containing metallic compounds and fluorocarbon polymers and are applied to surfaces of substrates such as metallic surfaces.
Abstract:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
Abstract:
A curable silicone composition which can cure using hydrosilylation, comprising an aluminum oxide powder and/or silica powder, the powders each consisting of substantially spherical particles with an average particle diameter of 50 µm or below and an elongation of from 1.0 to 1.4 and being such that the respective amounts of alkali metal ions and halogen ions are extracted with 50 ml of water from 5 g of the powder at 121°C for 20 hours are not more than 10 ppm, wherein the amount of the component (D) is from 25 to 90% by weight based on the composition, and the ratio of the amount of hydrosilyl groups contained in the components (A) and (B) to the amount of alkenyl groups contained in the components (A) and (B) is in the range from 0.5/1 to 1.5/1. When the composition is used as a protective material or encapsulating material for devices such as ICs, generated heat can be dissipated efficiently and the devices are not be broken by abrasion. There are no fears of causing corrosion of the devices.

Abstract:
There is provided a galvanized steel sheet with high press formability, which has an inorganic compound on a metallic galvanized layer thereof. The galvanized steel sheet according to the present invention is manufactured by bringing the plating surface of the galvanized steel sheet into contact with a water solution containing 0.1 wt% or more of a borate of alkaline metal, and then drying the steel sheet by heating within a temperature range of 60 to 400°C. The friction coefficient of the galvanized steel sheet of the invention is 80% or less of the friction coefficient obtained without the existence of the inorganic compound on the metallic galvanized layer and the amount of insoluble slimes of the inorganic compound left after water washing or alkali degreasing is less than 1 mg/m².
Abstract:
