Reliable German engineering

We have tried other brands, but the consistency of the Plasmatreat liquid is superior. It gives us confidence in our adhesion testing processes.

Clear results every time

No ambiguity in the test results. The liquid beads or spreads clearly depending on the surface tension. A staple in our production line.

Good range, fast drying

Works well for our lab needs. The liquid dries quickly which speeds up our workflow, though you need to be precise with your application timing.

Essential for quality control

This dyne pen is incredibly accurate for testing our plastic substrates before printing. The green ink provides excellent contrast, making it easy to read the results immediately.

Effective but pricey

The product works exactly as described and is very reliable. However, the cost per unit is higher than some competitors, even if the quality seems better.
