Paint and Coatings Friction Testing -- Falex Pin and Vee Block Tester

Touchstone has developed custom tests used to measure the coefficient of friction in paints and other organic coatings.

Electrical conduit is often purchased based upon how easy it is to pass wires through it after it is bent into shape and installed in a building. The easier it is to pass the wires through the conduit, the higher the perceived value of the product. Touchstone has developed a device which measures the friction of wires against the inside wall of steel electrical conduit. It has been used for the purpose of internal coating selection.

Touchstone has also developed custom tests to measure the coefficient of friction of painted flat surfaces.

Touchstone is also experienced in the performance of frictional measurements of thin film lubricants utilizing a Falex Pin and Vee Block Tester (shown above).

The Pin and Vee Block Tester can measure two qualities of a lubricant. Its lubricity, and the maximum pressure it will withstand before the lubricating properties fail. This work can be performed at various temperatures. It operates by having a small, rotating, cylindrical pin squeezed between two metal arms with vee-notched blocks attached.

If you have a need to measure the surface friction, please contact us at TRL.
