Good but pricey

The liquid works exactly as described and is accurate. However, it is quite expensive compared to some generic alternatives. You pay for the brand reliability and certification, which matters for audits, but it adds up.

Reliable German engineering

Great product overall. The tension values are consistent with our calibration standards. Only giving 4 stars because the bottle cap can be a bit tight to open quickly during high-volume testing, but the liquid quality is top-notch.

Essential for our QC lab

We use these dyne liquids daily to test film adhesion before printing. The pink series is very clear to read and the brush applicator makes it easy to apply a thin, even layer. Highly recommended for industrial quality control.

Clear results every time

As a technician, I appreciate how distinct the wetting behavior is with this solution. It eliminates guesswork when determining if a surface is treated enough for ink adhesion. Will reorder soon.

Perfect for coating analysis

I work in R&D for packaging materials. This liquid provides immediate visual feedback on surface energy. It has helped us troubleshoot several bonding issues with our new polymer blends. Fast shipping too.

Standard in our facility

We have been using arcotest products for years. This specific pink series liquid is perfect for the mid-range dyne levels we test most often. No evaporation issues if stored correctly.

5 FAQ

Q: What is the shelf life of this liquid once opened?

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

Q: Does this come with a calibration certificate?

A: Yes, each batch of arcotest liquids comes with a batch-specific certificate of analysis confirming the surface tension value at the time of manufacture.

Q: How should I store this product?

A: Store the bottle upright in a cool, dry place away from direct sunlight and heat sources. Keep the cap tightly closed when not in use to maintain the integrity of the solution.

Q: Is this safe to use on food packaging materials?

A: Yes, the arcotest Pink Series is commonly used in the food packaging industry to test surface treatment. However, ensure the tested area is cleaned or discarded if direct food contact is a concern, as the liquid itself is a chemical reagent.

Q: Can I use this on metal surfaces?

A: While primarily designed for plastics and films, this liquid can be used on coated metals to test the efficacy of primers or coatings. It is not intended for testing raw, uncoated metal surface energy.
