Corrosion inhibitor composition for formulated polyol ester fluids

摘要

Corrosion inhibition in polyol ester lubricant compositions is achieved by the inclusion in the lubricant of a mixture of a hydroxyamine (e.g., bis(2-hydroxyethyltallowamine) and an alkyldiamine dicarboxylate (e.g., N-tallow-1,3-diaminopropane dioleate).
