About Dyne Pens to ISO 8296

Dyne Test Pens are a cost effective, quick and easy method to measure surface wetting or surface energy. Sometimes known as corona test pens or sherman pens the Dyne Test Pen is a simple method of determining the surface energy of most polymer based materials.

Dyne test solutions are often used during plasma surface modification, corona surface treatment and flame treatment to determine the surface energy level and cleanliness of a substrate, especially within industries such as packaging and converting, automotive, aerospace, medical device manufacturing etc.

Our Dyne Test Pens are equipped with a valve tip applicator and do not suffer the inherent disadvantages of the “Magic Marker” or “Felt Tip Pen” type.

Quick & Easy to Use

To use simply draw the Dyne Test pen across the material surface, the liquid will either form a continuous film on the surface or draw back into droplets. If the Dyne test fluid remains as a film for 3 seconds or more then the material will have a minimum surface energy (Dyne level) in mN/m of that ink value. Should the Dyne test liquid draw back into droplets in less than 1 second then the surface energy (Dyne level) of the substrate is lower than that of the liquid value. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test pens.

Dyne Test Pens are available in a range of values from 30 to 72 Dynes/cm (mN/m) and are supplied in disposable pens.  The test fluid contained within the pens is to ISO 8296 with additional high visibility dye for easy readings.

Features & Benefits

  • Valve tip applicator resists contamination
  • Simple and quick surface energy measurement test

How It Works

Several types of Dyne Pens are readily available.

Most rudimentary is a nominal go/no go tester: Above a certain treatment, this pen marks the surface; below this level, the ink disappears. These pens identify and permanently mark the treated side of PE and PP films — aside from this, they have little use, since their initial accuracy is undocumented and their design is subject to contamination.

A second style is formulated at several dyne levels, enabling the user to test over a range of treatments. Generally, these markers are interpreted based on which dyne level takes closest to two seconds to form beads (similar to the standard ASTM and TAPPI methods). These test markers are easy to use and, when first used, often quite accurate. Unfortunately, their “Magic Marker” style nibs serve as perfect conduits for contamination of almost any kind, including machine oils, air born lubricants, plasticizers, slip additives, etc. The very wicking qualities which facilitate their use make them self-contaminating as well. This dynamic interaction between the instrument and the substrate essentially eliminates such wicking style applicators for serious dyne testing.

The Dyne Testing supplied ISO Type Dyne Test Pen is based on a valve tip applicator. The principle is simple: Keep the testing part of the pen away from the fluid storage part of the pen (in other words, no wicking from the substrate). By pressing the tip firmly down, the valve is opened and fresh fluid floods the tip; this flushes it clean, and allows the tester to lightly pass over the sample to accurately determine dyne level. Results are based on how long the test solution takes to form beads on the sample surface.
