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.

Perfect for coating verification
Using this to verify corona treatment levels on film rolls. The 28-72 range covers all our standard requirements. Highly recommended for industrial use.

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.
Q: How should I store these pens to maintain their accuracy?
A: Please store the pens horizontally in a cool, dry place away from direct sunlight and keep the cap tightly sealed when not in use to prevent evaporation.
Q: Is the green dye safe for use on food packaging materials?
A: While the liquid is used for testing, it is a chemical solution. We recommend verifying specific compliance certifications for indirect food contact applications with your regulatory team.
Q: What is the typical shelf life once the pen is opened?
A: Once opened, we recommend using the pen within 3 to 6 months for optimal accuracy, provided it is stored correctly and the cap is replaced immediately after each use.
Q: Can this be used on metal surfaces?
A: Yes, this dyne liquid is suitable for testing surface energy on various substrates including plastics, metals, glass, and coated surfaces.
Q: Does this pen cover the full range from 28 to 72 in a single unit?
A: Yes, the Type C Original pen contains a gradient solution that allows testing across the entire 28 to 72 mN/m range with a single application stroke.
