How Dyne Testing Works

Lotar LLC

Measuring Surface Readiness Through Dyne Testing

At Lotar LLC, we provide industry-recognized dyne testing solutions using test inks and test pens to help manufacturers evaluate surface energy. Dyne testing measures surface energy to determine whether a material is properly prepared for printing, painting, coating, gluing, bonding, and other adhesion-dependent applications.


During the testing process, a test ink or test pen with a known dyne value is applied to the surface being evaluated. The behavior of the liquid is then observed to determine whether the material has achieved the desired surface energy level. When the liquid remains as a smooth, continuous film, the surface energy meets or exceeds that dyne value. If the liquid beads up or retracts, contamination or inadequate surface treatment may be preventing proper adhesion.


By accurately measuring surface energy, Lotar helps manufacturers verify surface readiness, improve product quality, reduce adhesion failures, and achieve more consistent production results across a wide range of industrial applications.
