Abstract:
The tackiness of a lubricant grease is defined as the cohesiveness or stickiness of the grease and its ability to form thread-like structures when being pulled apart. The simplest method to determine the tackiness is through the finger test. This test is conducted by placing a small amount of your sample to be squeezed between your thumb and index finger and slowly pulling them apart. This allows for the tester to gain a qualitative estimate of low, moderate, or high tackiness. However, the subjective nature of this test causes variability in test results and a lack of standardization. In this poster, we observe how the K95200 Tackiness Tester conducts a similar type of test as the finger test but will produce a quantitative result by calculating the amount of force exerted to separate the sample between its two metal plates after its compression. This innovative and easy-to-use instrument is able to produce accurate and repeatable quantitative results for grease tackiness through the use of a standardized technique.
