Clear Results Every Time

The white formulation provides superior visibility compared to clear fluids we used previously. It dries at a predictable rate, allowing for precise dyne level assessment.

Standard in Our Facility

We have standardized on SHEELON fluids for all our surface energy testing. This specific white liquid is perfect for dark substrates where clear fluid is hard to see.

Essential for Quality Control

This SHEELON test fluid is incredibly accurate for checking our corona treatment levels. The white contrast makes it very easy to see the wetting behavior on our packaging films.

Good Value for Professional Use

A bit pricey compared to generic brands, but the accuracy and reliability of the German manufacturing justify the cost. No false positives in our tests so far.

Perfect for Calibration

We use this daily in our lab to calibrate our treatment processes. The consistency between batches is excellent, which is critical for our ISO compliance.

Reliable German Engineering

Works exactly as described. The brush applicator is convenient, though I wish the bottle was slightly larger for high-volume testing days. Overall, a solid product.

5 FAQ

Q: Can this fluid be used on metal surfaces?

A: Yes, while primarily designed for plastics and films after corona treatment, it can also be used to verify surface cleanliness and energy on metal substrates.

Q: Does the brush need to be cleaned after every use?

A: It is recommended to wipe excess fluid from the brush and ensure the cap is sealed tightly. Deep cleaning is generally not required if the bottle is stored properly, but replace the brush if contamination is suspected.

Q: What is the range of dyne levels covered by this specific bottle?

A: This specific product is formulated to test surface tension within the 29 to 105 mN/m range, covering most industrial plastic and film applications.

Q: How should I store the fluid to maintain its accuracy?

A: Store the bottle tightly closed in a cool, dry place away from direct sunlight and heat sources. Ensure the cap is sealed immediately after use to prevent evaporation.

Q: Is the white pigment safe for food-contact surface testing?

A: The fluid is for testing purposes only and should not remain on food-contact surfaces. After testing, the area must be thoroughly cleaned before any food contact occurs.
