Test inks 28 - 72 mN/m

Test inks are fluids for testing the surface tension of plastic foils, different plastic parts and various other materials. For this, the ink with a cotton swab, brush or stick form is applied like a highlighter. By this test means, our customer has the advantage to define a fast surface tension of its material.
