More Information
Summary:A lubricating oil composition for high-temperature applications, which comprises (A) a pyromellitic acid ester, (B) a sulfur -containing triazine type antioxidant, and (C) a thiophosphoric acid ester type antioxidant. When applied to chains, gears, bearings, or the like, the lubricating oil composition exhibits little evaporation loss over a long time and thus can be kept in a fluid state for a long time. Composition d'huile lubrifiante pour applications haute température, qui comprend (A) un ester d'acide pyromellitique, (B) un antioxydant de type triazine contenant du soufre et (C) un antioxydant de type ester d'acide thiophosphorique. Lorsqu'elle est appliquée à des chaînes, des engrenages, des paliers, etc., la composition d'huile lubrifiante présente une faible perte par évaporation sur une durée importante et peut donc être conservée à l'état fluide pendant une durée importante.
