FALEX TACKINESS ADHESION ANALYSER (TAA)
Developed from the tackiness and adhesion studies by Georgiou, Drees, et al, this is the first commercial benchtop test instrument to quantitatively measure tackiness and adhesion properties of greases or other lubricating materials. It has also been used to evaluate the stickiness of residues or deposits from metalworking fluids, or the remains of rolling emulsions..

- ASTM Standard method
- The stylus (a 3 mm copper ball) is pushed into the grease sample with controlled force. Motion is then reversed to effect the retraction of the ball from the grease sample. This motion is made at a precisely controlled initial acceleration and speed. During the test operation, a highly accurate and precise measurement system is used to record the force of the ball moving within the grease. High speed data collection makes detection of small changes in force measurement possible. Retraction can be programmed with different speeds and initial accelerations up to 80 m/s2. The grease sample can be heated to temperatures from ambient (no heat applied) to 100°C. Other geometries and materials can be used for the stylus.
