  • Extreme pressure metal sulfonate grease
    Patent number: 11078438
    Abstract: An overbased metal detergent grease comprising at least one of polyalkylene glycol and/or an acid having at least one of both a nitrogen and a sulfur atom. The grease has improved extreme pressure performance as measured by the Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method), ASTM D2596. Methods of making an overbased metal detergent grease comprising using at least one of polyalkylene glycol and/or an acid having at least one of both a nitrogen and a sulfur atom. Methods of lubricating mechanical components using the grease comprising contacting the mechanical component with the grease. Mechanical components can include gears, drivetrain elements, bearings, hinges, or combinations thereof.
