Key to any surface treatment application is knowing your starting and ending treatment levels. Enercon’s EnerDyne™ pens provide a quick, safe and simple means of testing surface energy.

Unlike traditional dyne pens that are made with toxic solutions such as formamide, EnerDyne™ pens are toxic free making them safe for your operators. They also provide vivid easy to read results on a wide variety of surfaces.

EnerDyne™ pens are designed to indicate surface treatment levels on polymer-based substrates and establish that the material is correctly treated prior to applying inks, coatings, paints or adhesives.

 Pens are available in 30/32/35/38/41/44/48/56/60/66 dyne levels and are available as single dyne levels packs or as mixed packs.

EnerDyne™ Pens
  1. Remove the pen cap and briefly depress the tip on a clean surface until moist
  2. Apply the solution over a test area of approximately 2.5 cm square
  3. Note the required time for the applied solution to break into droplets and/or peripheral shrinkage to occur. Read the solution behavior by observing the center area of the applied solution. If the dyne solution does not break into droplets and/or peripheral shrinkage after 4 seconds, repeat the test with the next higher surface tension solution. If the solution breaks into droplets and/or peripheral shrinkage in less than 4 seconds, repeat test with next lower surface tension solution.
  4. Do not repeat test on the same area of material
  5. Repeat Steps 1 and 2 until the correct dyne level is determined. The correct dyne level will be equal to the solution that holds for exactly 4 seconds before droplets or peripheral shrinkage occur
  6. As a general guideline surface coverage tension should be approximately 10 dynes higher than ink, adhesive, or coating. This may not be the case for every application
  • Use of excessive solution will result in a false reading
  • Dyne Pens typically have a 6-12 months shelf life
  • Each pen is rated for the minimum dyne level that the ink will determine
  • Surface energy testing should be conducted immediately after treatment
  • Treated surfaces are time sensitive and are affected by environmental conditions such as temperature and humidity
  • Do not touch or contaminate the surface to be tested. Dirty surfaces lose their wettability; therefore, clean test level area
  • Do not use contaminated or outdated pens
  • Store and use pens at room temperature
  • The inks should not be exposed to direct light. Therefore, keep them closed when not in use. Also, repeated ink exposure to air, will alter the dyne levels. Properly sealed pens prevent this from occurring
  • Inconsistent or excessive pressure may provide a false dyne level reading
