Surface tension

A possibility for the determination of the surface tension is the application of test inks according to DIN ISO 8296. If the applied fluid converges immediately after the application in this experiment, the tension of the sample is smaller than the defined surface tension of the ink and you continue with the next more stress-relieved ink. If the applied stripe stays more than two seconds stabile, the surface tension of the examined sample corresponds to the value of the test ink. In the measuring range of 18 to 72 mN/m we offer with this method measurements for the prevalent plastics and even steels.

Normen: DIN ISO 8296, DIN 53364
