diurea thickener compatibility test

  • Grease Compatibility Chart The Lubricant Store

    15 rowsMixing greases in a system can cause issues with thickener systems reacting with each other. This can change the physical and chemical structure of the grease, causing an inability to hold or release the base oil. The resulting grease carries unknown performance characteristics (load, temperature stability, shear, etc.). Proper care must be taken to ensure compatibility

  • Grease Compatibility Chart and Reference Guide

    Grease compatibility is often confusing to grease users, even though most grease manufacturers produce compatibility charts. This is because the charts from the various manufacturers often disagree with one another on certain thickener type combinations. In bygone days, when simple soaps and clay were the primary thickener types, compatibility
