HiTEC® 552 is a reliable grease additive package that combines extreme pressure and antiwear performance with basic rust protection and antioxidancy. HiTEC® 552 is carefully formulated to resist degradation of critical grease properties such as dropping point and stability in the presence of water. This system can be used by itself in a variety of economy-tier, multipurpose greases that require basic EP/ AW and corrosion protection. It can also be used as a core “building block” with additional top treats being used to give required performance for specialty grease applications.
Max Handling Temp: 80°C
