Idemitsu NTG KINGSTAR EP No.1 / No.2 Organomolybdenum Extreme-Pressure Lithium Grease
KINGSTAR EP is an extreme-pressure lithium grease formulated with high-quality refined mineral oil as the base oil. It contains organomolybdenum compounds, polymers, EP additives and antioxidants to provide strong adhesion, water resistance, heat resistance and mechanical stability. The high level of organomolybdenum gives the grease particularly good anti-wear performance, making it especially suitable for construction machinery and other equipment operating under heavy loads, shock and vibration. The main difference between No.1 and No.2 is consistency. No.1 has a worked penetration of 325, making it softer, while No.2 has a worked penetration of 278, giving it firmer consistency and better retention in some applications.
