Lubricant for conveyor chains

Abstract

A lubricant for conveyor chains, the lubricant consists of a mixture of a quantity of fatty acid, a quantity of amine, a quantity of polyglycol, and a quantity of hydrocarbon. The lubricant of the invention uses a direct application, without dilution, and forms a layer or film of lubricant on the surface of the conveyor chain so that the application is discontinued, in long intervals between the applications.
