Accu Dyne Test Pens 30-72, The Marker Pens for testing the film surface  are made with reagent grade dyne testing fluids and employ a spring-loaded valve tip that keeps contaminants on the tip from affecting the accuracy of the test fluid in the test marker’s barrel.


Accu Dyne Test Pens 30-72 which 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). The diagram demonstrates how that’s accomplished; 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.

For the results of this Accu Dyne Test Pens to be meaningful, the following four points are absolutely essential and must be followed:

1) Do not touch or in any way contaminate the surface to be tested. Dirty surfaces lose their wettability.

2) Do not use contaminated or outdated ACCU DYNE TEST™ marker pens.

3) Never retest the same location on a sample; move along the sample, or pull a new one.

4) Store and use ACCU DYNE TEST™ marker pens at room temperature.

ACCU DYNE TEST ™ supplies a complete range of Dyne Pens (which are also referred to as Corona Pens) to measure surface energy. Using a ACCU DYNE TEST ™ Marker Pen gives quick and easy results indicating surface wettability. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings.

To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface Treatment with either Corona or Plasma results in good wetting of the material over the surface of the substrate and so improves adhesion. For optimum adhesion when printing, gluing or coating on various substrates, it is necessary to obtain a high surface energy. Determining the surface energy can be achieved by measuring contact angle or by use of Surface Energy Test Pens (Dyne level testing). The fluid contained within the pens is based on the ISO 8296 method for measuring the surface energy of polyethylene film.

When the Accu Dyne Test Pens level   is applied to the surface, the liquid will either form a continuous film on the surface or pull back into small droplets. If the Dyne test fluid remains as a film for 3 seconds, the substrate will have a minimum surface energy of that ink value, expressed in mN/m (Dynes). Should the Dyne test liquid reticulate or draw back into droplets in less than 1 second then the surface energy of the substrate is lower than that of the liquid itself. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test pens.
