Unlike the compatibility of oils, which is most often related to interactions of the additives in the products (and sometimes the nature of the base fluids themselves), the compatibility of greases is most often related to the thickener types of the products to be mixed (although base fluid compatibility
Note: The compatibility charts should be used as a reference only.Compatibility testing is the only way to verify compatibility. A significant portion of grease lubrication failures can be attributed to mixing greases in a system without taking into consideration compatibility. Different thickener systems can react with each other to modify
Thickener Compatibility Mixing of greases with incompatible thickeners can result in the most immediate and obvious changes that interfere with effective lubrication. Many mixtures will initially soften, often to the point of migration through seals or away from lubricated surfaces.
While the compatibility of oil products is largely related to the base and additives, grease compatibility is connected to the types of thickeners used. Technological advances have made grease compatibility a much more complicated proposition with the wide and complex array of thickeners used.
A grease thickener can influence your grease’s operating temperature, load, speed, and material compatibility. Thus, it is key you determine which thickener is best suited for use in your specific application. This article features the organic soaps from the range of thickeners
Table 1: Grease Compatibility Generic Chart NOTE: This matrix is based on information commonly used in industry. It provides a general assessment of grease compatibility based upon the structural stability of mixtures of different grease thickeners. It does not address potential additive related incompatibilities or other performance features.

grease compatibility chart A significant portion of grease lubrication failures can be attributed to mixing greases in a system without taking into consideration compatibility. Different thickener systems can react with each other to modify the physical and stone structure resulting in the inability to hold or release the base oil.
How to Determine Grease Compatibility and Why It’s ... thickener used in the formula- and also the type of base fluid used. Here's what Acculube believes is a good basic compatibility guideline, based on its 25+ years of experience working hands-on with users of ... Thickener compatibility Reliable Plant 2016 Conference Proceedings .
The thickener compatibility chart below should be used as a guide to determine compatibility only. Compatibility testing is the only way to verify end product compatibility. Other factors including environment can affect the compatibility of the finished product including temperature, load
Compatibility: This is one of the most important grease properties. Whenever two incompatible thickeners are mixed, grease usually becomes soft and runs out of the bearing. When mixing different thickener types, consult supplier on compatibility. Some incompatible thickeners are aluminum and barium soaps, clay and some polyureas. Pumpability
Broad latex compatibility Potential for thickener consolidation Low-viscosity liquid Ease and convenience of handling Synthetic Resistance to microbial attack Excellent flow and leveling Minimal brush marks Physical Properties The following properties are typical of ACRYSOL RM-7 but should not be considered specifications. The actual
AEROSHELL GREASES THE DEFINITION OF A GREASE IS: “A solid or semi-solid lubricant comprising a dispersion of a thickening agent in a liquid ... the compatibility of their products with a range of other materials. Therefore the information provided can only be considered as guidelines.
Choosing the Right Grease Thickening System: Non-Soap Thickeners. There are several non-soap thickeners that have been developed over the years and are utilized in applications depending upon the operating conditions the grease will experience and the materials with which they will be in contact.
The advanced thickener formulation and proprietary manufacturing techniques provide improved bearing performance and protection for long electric motor life. ... For specific questions about grease compatibility, contact your Mobil representative. Key applications include: Electric motor bearings; Fin
A Practical Guide to Thickener Selection. October 23, 2000. Reprints ... As with eggshell paints, HMHEC can be used as a co-thickener to improve sag resistance and colorant compatibility; usage levels can be as high as 25% of the total thickener package before gloss and leveling are reduced.
