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.
How does dyne pen work?
When the Dyne level test fluid 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).
How does dyne testing work?
In a dyne test, wetting tension liquids are spread over a film surface to determine printability, coating laydown, and heat sealability of treated films. Solutions of increasing wetting tensions are applied to the polymer film until a solution is found that just wets the polymer surface.
