SURFACE TENSION MEASUREMENT
Surface tension measurement helps ensure proper adhesion compatibility between inks, coatings and substrates. A wide range of products is available to help depending on the type, size and level of measurement needed. Surface tension is measured in Dynes/cm. To allow the best possible compatibility with inks to a substrate, the surface tension must be approximately the same as the substrate. To allow the printing and adherence of plastic substrates and other non-porous materials such as polymer, the surface must be treated so the surface tension rises to a defined point.
based Polymer-Ink dyne pen is often used as a “treat/no treat” test pen
on polyethylene and polypropylene film. Available with either blue or red
ink, the non-cancerous dyne solution is very dark and more environmentally
friendly than standard pens. Available only as a 38-40 range pen, it is
intended for those who normally only use one pen (as opposed to those
testing over a broad range).
CON-TROL-CURE® Liquid Dyne Pen's spring-valve tip design keeps the pen's
applicator away from the dyne fluid storage to prevent contamination. Press
the tip firmly down to open the valve and flood the tip with fresh fluid.
Available in sets of 8 pens from 30 to 44 dynes/cm (30, 32, 34, 36, 38, 40,
42, 44) and from 46 to 60 dynes/cm (46, 48, 50, 52, 54, 56, 58, 60); also
available by special order at any level from 30-60 dynes/cm.
NOTE: ALL PEN ORDERS MUST BE PURCHASED IN QUANTITIES OF 8 ONLY; EITHER IN SETS OR MIX-AND-MATCH DYNE LEVELS ACCORDING TO YOUR SPECIFICATIONS.

CON-TROL-CURE® Felt Tip Dyne Pens. These chisel-tip markers provide a
quick, clean and easy method of testing treatment levels on polymer
plastics. The simple application of a dyne pen to the surface or printing
side of the tested material will determine its surface tension value, which
proves if the wettability of the pen's designated dyne level has been
This 6 pen magic marker-type pen set quickly and effectively verifies whether a substrate is treated from 36 up to 48 dynes/cm. If the material is properly treated, the applied dyne mark is uniform, resulting in a continuous and homogenous colored line. If the material is insufficiently treated, the line of the dyne test retracts in the form of small globules until the mark nearly disappears. Set includes pens in 6 levels: 36, 38, 40, 42, 44 and 48 dynes/cm. 6 month shelf life.
Test Solutions are another way printers, converters and
extruders can determine surface energy levels. Ranging
from 30-60 dynes/cm, these solutions offer an easy and
effective method of testing. By wetting the tip of a
cotton applicator with one of the mixtures and spreading a
line over the test specimen, users can verify treatment
within 2 seconds. If the continuous line holds for 2
seconds or more, users can be assured that the material is
treated to within 1 dyne of that specific solution.
