Test inks 28 - 72 mN/m

Test inks are fluids for testing the surface tension of flat sheets and plastic parts. For this, the ink with a cotton swab, brush or stick form is applied like a highlighter. By this test means, our client has the advantage to define a fast surface tension of its material. Test inks are available in the ranges 28 - 72mN/m (non-toxic) in 10ml, 30ml, 50ml, 100ml and 1000ml PET bottles. The 10ml bottles are equipped with a brush inside the lid. The advantages of the ink are that our customer can apply this fast, when using a cotton swab to remain any dirt residue back into the ink (one-time use of the cotton swab provided)

The durability of the ink depends on the frequency of use of ink or pens.

- With more than once daily use for about 3 months

- For weekly use around 6 months - For occasional use >12 months (Assuming an immediate closure of the bottle or the pen is immediately after use)
