Essential for our quality control lab

We use these pens daily to verify corona treatment on our packaging lines. The Taixing brand provides consistent results compared to more expensive alternatives. The ink flow is smooth and the drying time is perfect for quick assessments.

Solid performance

The pen delivers a clear line that beads up or spreads exactly as expected based on the surface energy. Shipping was fast and the packaging protected the pen well during transit.

Perfect for adhesion testing

Bought these to test adhesion potential before applying labels. They are very user-friendly; even new staff members can learn how to use them within minutes. Great product for the price point.

Reliable industrial standard

Been using Dyne pens for over a decade in the printing industry. This specific model from Taixing is reliable and easy to read. It clearly shows whether the substrate is ready for printing or lamination.

Consistent and durable

We ordered a bulk set for our factory floor. Every pen in the batch performed consistently. The ink does not dry out quickly even with intermittent use, which saves us money in the long run.

Good value, accurate readings

These pens work well for testing PE and PP films. I deducted one star only because the cap can be a bit tight sometimes, but the accuracy of the surface tension measurement is spot on for our needs.

5 FAQ

Q: Is safety data sheet (SDS) available for this product?

A: Yes, an SDS is available for all our chemical testing products. You can download it directly from the 'Documents' section of this product page or request it via our customer support email.

Q: What is the shelf life once the bottle is opened?

A: Once opened, we recommend using the pen within 6 months for optimal accuracy, provided the cap is sealed tightly immediately after each use to prevent solvent evaporation.

Q: What range of dyne levels does this specific pen test?

A: This specific listing is for a single value pen. Please select the specific dyne level (e.g., 38, 40, 42 dyn/cm) you require from the variation options at checkout. We sell individual pens ranging from 30 to 72 dyn/cm.

Q: Can these pens be used on metal surfaces?

A: While primarily designed for plastics, films, and foils, they can technically be used on coated metals to check for cleanliness or coating integrity. However, they are optimized for non-porous polymer substrates.

Q: How should I interpret the results when using the pen?

A: If the liquid line remains intact without beading for at least 2 seconds, the surface tension of the material is equal to or greater than the pen's value. If it beads up immediately, the surface tension is lower than the pen's value.
