Product Details

Jemmco’s Accu-Flo™ Jumbo Dyne Pens are a valve style pen, which releases fluid by pushing down on the tip. The ¼” wide x ½” long felt tip, regulates the amount of fluid released to the substrate, producing a wide, consistent line, that is easy for the user to read. The refillable barrel holds just under 1.5 ounces of fluid for long, continuous use. These pens are ideal for covering large surface areas. The nice, wide, dark blue stripe is easier to read, making it the perfect pen for identifying treat patterns and back side treatment. When supplied filled with Jemmco dyne solution, the solution is supplied in a separate, hermetically sealed 2 oz. container, marked with the dyne level and the anticipated expiration date. Jemmco Accu-Flo™ Jumbo Dyne Pens are a perfect way to dispense low viscosity liquids. The screw on cap makes it easy to fill, and easy to clean. The Jemmco Accu-Flo™ Jumbo Dyne Pens features a replaceable felt tip in order to assure continued accuracy.

  • Available in dyne levels ranging from 30 dynes up to 70 dynes, in increments of one dyne level
  • Pens measure 1" in diameter and 6.25" long
  • Can be ordered filled or unfilled
  • Features replaceable felt tip in order to assure continued accuracy

How it Works

With Jemmco Accu-Flo™ Jumbo Dyne Pens the user simply marks a line on the substrate in question, and counts three seconds. If the line does not breakup within two seconds, the substrate is either at the level of the marker used or higher. If the line starts to break up before the three second count is finished, then the substrate being tested is below the level of the marker used. The ideal surfaces for Dyne Pens are non-absorbent materials. It is necessary to obtain a high surface energy for ideal adhesion when printing and gluing various substrates. The test fluid should not alter the surface properties of the substrate.





Helpful Tips

o Inconsistent pressure may provide a false dyne reading
o Touching the surface to be tested could result in contamination
o Usable on almost any smooth and non-absorptive substrates
o Reliable for R&D and lab applications
o Pens should be stored at room temperature
o Contaminated pens should not be used
o 5-6 month shelf life
o Dyne pens should not be exposed to direct sunlight, therefore they
should be closed when not in use
o Dyne level decay is very quick directly after corona treatment


What Type of Dyne Pen Is Best?

There are a large variety of Dyne Pens on the market, and, in fact, Jemmco offers a wide number of styles. Despite all of these variations, there are basically two types. One type is the valve type pen, in which a valve is opened up to release the dyne solution when the pen tip is pressed down. This type of pen had been very popular, based on the belief that any surface contaminants picked up on the tip would be washed away with the solution once the valve was opened. Of course, this makes no sense since the contaminants would then be deposited on to the substrate being measured and would be affecting the solution that was used to measure the treat level of the substrate. A secondary issue with these pens is that it adds another variable to the dyne test. Since the amount of fluid released is dependent upon how much time, and how hard the user presses on the tip, it is very easy for too much fluid to be released, flooding the substrate surface, which could result in a false reading.

The second type of pen style available is a wicking type pen. Similar to a magic marker, this style pen does face the same problem as the first, regarding tip contamination, however, the solution flow is now dependent on the wicking action of the pen and not the operator. As a result, the amount of fluid deposited on the substrate is more consistent from use to use, thus eliminating one variable.

Jemmco does offer a valve style pen, our Accu-Flo™ Jumbo Pen, which uses a thick replaceable felt tip, to reduce the amount of fluid deposited, and to reduce the impact of tip contamination.

Why Accu-Flo™ Dyne Pens?

Jemmco’s Accu-Flo™ Dyne Pens are simple to use, making them perfect for use in applications where a quick reference is needed. The dark blue color solution makes them easy to read, especially in poor lighting. For this reason, these pens have proven to be perfect for use at the production line. The wicking style marker provides a constant volume of solution with each swipe, enabling more consistent results each time. They are available in even dyne levels ranging from 32 dynes through 58 dynes, which covers a wide range of applications. Best of all, Accu-Flo™ Dyne Pens are competitively priced.

Jemmco’s Accu-Flo™ Dyne Pens are made specifically for each order, so that the user is assured that the pens are fresh and have not been sitting on a shelf. Jemmco puts an anticipated expiration date on each pen to remind the user when it is time to reorder. (note: The expiration date appearing on the pen is a not to exceed date. Pen life is dependent on use, storage conditions and exposure to the atmosphere. Pen solution that has turned green will not give reliable readings and should not be used.)

Accu-Flo™ Dyne Pens have proven to be very popular with film extruders and plastics converters. Providing a good, quick reference in production environments, users have learned to depend on Jemmco Accu-Flo™ Dyne Pens.

How Should I Store My Accu-Flo™ Dyne Pens?

Accu-Flo™ Dyne Pens should be stored at room temperature with the cap on tight to prevent drying out. The Dyne Pens should not be exposed to direct sunlight.
