Test inks: Surface determination by Plasmatreat test inks

Quality assurance in plasma pretreatment

In ongoing processes the measurement of surface tension with Plasmatreat test inks is an outstanding aid to quality assurance during production*. The key requirement is always that the adhesive or printing ink and state of the surface be matched to one another in optimum fashion.

Plasmatreat test inks are available  in sets of different sizes	Test ink sets can be put together in  various Dyne sizes

Plasmatreat test inks are supplied in three different series:

Series A – especially suitable for warmer surfaces
Brief description: Longer read-off time, not suitable for PVC surfaces, toxic, produced in accordance with DIN 53 364, suppliable from 30 - 56 mN/m (in steps of two units)

Series B – suitable for all common surfaces
Brief description: Some are toxic (depending on value of surface tension), produced in accordance with DIN 53 364, suppliable from 28 - 72 mN/m (in steps of two units)

Series C – suitable for all common surfaces
Brief description : Non-toxic, not harmful to health, produced on the basis of DIN 53 364, suppliable from 28 - 72 mN/m (in steps of two units)

* The maximum error of measurement is 2 mN/m. In test series with multiple measurements error tolerances fall accordingly. The measured values obtained are relative values and comparable with other test methods only to a limited degree.
