Does the job
Simple and effective tool for detecting grease and oil contamination. Instructions could be more detailed, but if you know how dyne pens work, these are great.

Reliable adhesion testing
Perfect for verifying corona treatment effectiveness on packaging materials. The distinction between wetting and beading is very clear with these pens.

Essential for our print shop
We use these daily to check surface tension on plastic films before printing. The 38 and 42 dyne pens are our most used. They provide consistent results and help us avoid adhesion failures.

Accurate and durable
I've been using Cuiyuan pens for years. This batch is just as good as previous ones. The felt tips hold up well even after hundreds of tests.

Great for QC department
We bought the full set of tensions (32-44). Having the range allows us to pinpoint the exact surface energy of various substrates. Highly recommended for manufacturing QA.

Good value for money
Works as expected for quick quality control checks. The ink flows smoothly. I deducted one star because the cap can be a bit tight to remove quickly during high-volume testing.
Q: Do you offer bulk discounts for purchasing multiple sets?
A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly through the 'Contact Seller' button on our store page for a custom quote.
Q: Can these pens be used on metal surfaces?
A: Yes, these dyne pens can be used on metal, provided the surface is clean and free of heavy oils. They are commonly used to check cleaning efficacy on aluminum and steel prior to coating.
Q: Is the ink toxic?
A: The ink contains formamide and should be handled with care. Avoid contact with skin and eyes, and do not ingest. Please refer to the Safety Data Sheet (SDS) included in the package for detailed safety information.
Q: What is the difference between the 40 and 42 dyne pens?
A: The number indicates the surface tension in dynes/cm. A 42 dyne pen requires a higher surface energy to wet out than a 40 dyne pen. You select the pen based on the minimum adhesion requirement for your specific ink or glue.
Q: How long does the ink last once the pen is opened?
A: Once opened, the pen should typically last 3 to 6 months depending on frequency of use. Always recap tightly immediately after use to prevent evaporation.
