Abstract:
Grease tackiness is a measure of the adhesive properties of a grease sample. These adhesive properties are the result of the high-weight polymers that greases are comprised of. Currently, the most common method of testing a grease’s tackiness is to use the finger test. The finger test is a qualitative test in which the tester places an unspecified amount of sample between their thumb and index finger and pull them apart to determine if a grease is of low, moderate, or high tackiness. In this poster, we discuss the development of a new instrument and procedure analogous to the finger test, but with quantitative results. The principle of pulling apart grease with one’s fingers is standardized with two metal plates that can accurately measure the force exerted to separate the sample. We have run tests on numerous grease samples with our new instrument in an attempt to generate a new test procedure along with repeatability and reproducibility for this refined technique.
