Good quality, fast shipping

Ordered a full set from 30 to 38. They work exactly as expected for our QA process. Only giving 4 stars because the cap on one pen was slightly loose upon arrival, but it didn't affect performance.

Solid product

Does the job well. We use them daily to ensure our substrates are ready for adhesion. The shelf life seems decent too, provided you cap them tightly.

Reliable testing tool

We have switched from liquid bottles to these pens for ease of use in the factory. The A.shine series provides clear wetting results immediately. Highly recommended for corona treatment checks.

Best value for money

Compared to other brands, these offer better consistency in the ink formulation. The 32 and 38 values were spot on when cross-checked with our electronic tensiometer.

Perfect for lab work

Precise and clean to use. No mess compared to traditional cotton swab methods. The distinction between wetting and beading is very sharp with these markers.

Essential for our printing line

These dyne pens are incredibly accurate for checking surface tension on our polyethylene films. The 34 and 36 sizes are what we use most often, and the ink flow is consistent every time.

5 FAQ

Q: Is the ink toxic or hazardous?

A: The ink contains solvents typical for dyne tests. Please refer to the SDS sheet included with the shipment for specific safety handling and disposal guidelines.

Q: Can these pens be used on metal surfaces?

A: While primarily designed for plastics and films, they can be used on coated metals to test organic coating readiness, but results may vary on bare metal.

Q: What is the shelf life of these dyne pens once opened?

A: Once opened, the pens typically remain effective for about 6 months if stored upright with the cap tightly sealed at room temperature.

Q: How should I store these pens to maintain accuracy?

A: Store them horizontally or with the tip down in a cool, dry place away from direct sunlight to prevent the solvent from evaporating.

Q: Do you sell a kit containing all sizes from 30 to 38?

A: Yes, we offer a complete bundle pack that includes one pen of each size: 30, 32, 34, 36, and 38 mN/m.
