Superior to generic brands
Switched from a cheaper brand to A.shine and noticed the difference immediately. The wetting behavior is distinct and easy to read, reducing operator error in our cleanliness tests.

Reliable industrial standard
We have been using A.shine dyne pens for years. They are the industry benchmark for verifying surface cleanliness and treatment levels before printing or bonding.

Accurate but requires care
Very precise for surface energy testing. You must cap it immediately after use to prevent evaporation, which can alter the dyne level. Overall, a great tool for quality control.

Essential for our packaging line
We use these pens daily to check corona treatment on our polyethylene films. The German standard ensures consistent results, and the ink flow is reliable across the entire 21-72 range.

Good product, shipping delay
The pen itself works exactly as described for surface tension measurement. However, the shipping took longer than expected. The product quality makes up for it though.

Perfect for R&D lab
Our lab uses these for adhesion testing on various substrates. The wide range of sizes available allows us to test everything from low-energy plastics to treated metals without buying multiple kits.
Q: Does the color of the ink change over time?
A: The ink color should remain consistent throughout its shelf life. If you notice significant fading or sedimentation before the expiration date, the pen may have been exposed to improper storage conditions and should not be used for critical tests.
Q: Is this pen suitable for testing metal surfaces?
A: Yes, while commonly used for plastics and films, these dyne pens are also effective for checking the cleanliness and degreasing status of metal surfaces prior to painting or bonding.
Q: Can these pens be refilled once the liquid runs out?
A: No, A.shine Dyne Pens are designed as single-use disposable tools to ensure the accuracy and purity of the test solution. Refilling may compromise the calibrated dyne level.
Q: What is the recommended storage temperature for these pens?
A: For best results, store the pens in a cool, dry place between 15°C and 25°C (59°F - 77°F). Avoid direct sunlight and extreme temperatures to maintain liquid stability.
Q: How do I know if the surface tension is sufficient using this pen?
A: Draw a line with the pen on the surface. If the liquid remains beaded up within 2 seconds, the surface tension is lower than the pen's value. If it spreads evenly and wets the surface for at least 2 seconds, the surface tension meets or exceeds the pen's rating.
