    摘要: An improved urethane pre-polymer-based surface coating comprising a mineral filler the improvement comprising a benzothiazolythio compound and arylsulphorylisocyanate compound. A method of delaying or preventing the cross-linking or gelation of a urethane pre-polymer-based surface coating prepared with a mineral filler, comprises adding to of the formulation the surface coating a benzothiazolythio compound and an arylsulphonylisocyanate compound in amounts effective to prevent or delay the cross-linking or gelation of the surface coating.

    摘要: The natural rubber of the present invention is natural rubber obtained by leaving standing for a prescribed period of time a hydrous coagulum obtained from a natural rubber latex to which a preservative is added and/or from a coagulum of a natural rubber latex to which a preservative is added and drying it. The natural rubber coagulum is inhibited from being changed in a molecular weight even in a standing step (aging) in a high moisture condition, whereby the natural rubber having stable mechanical properties is obtained. An isothiazoline base compound is used for the preservative. Further, a rubber composition containing the natural rubber is prepared, and a tire is produced by using the rubber composition.

    摘要: The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein.
