Abstract Information :
Greases are lubricating agents generally used to reduce friction within machinery to prevent corrosion and damage. Greases are typically formulated from a base oil, thickener, and other additives, all of which may influence their physical properties and applications. Tackiness may be defined as the measurement of a materials adhesive and cohesive properties, and its ability to form threads when pulled apart. Techniques, such as the finger test, produce a qualitative measurement of the tackiness of a grease, but create issues in standardization due to imprecise and non-quantifiable conditions. To standardize the measurement of a greases tackiness, instruments, such as the K95200 Tackiness Tester, can quantify the tackiness of a grease sample. This instrument standardizes the measurement of tackiness by measuring the exact force exerted on the grease sample when being stretched in a method that is reproducible. The data is collected and displayed in a quantified standard measurement that can be used to compare various greases. Being able to accurately compare greases in this manner is important to choosing the best-suited grease for the desired application. This poster will explore the Kesternich method of gathering standardized measurements of grease tackiness.
