Dyne Test Pens are a cost effective, quick and easy method to measure surface wetting or surface energy. Sometimes known as corona test pens, the Dyne Test Pen is a simple method of determining the surface energy of most polymer based materials.Dyne test solutions are often used during plasma surface modification, corona surface treatment and flame treatment to determine the surface energy level and cleanliness of a substrate, especially within industries such as packaging and converting, automotive, aerospace, medical device manufacturing etc.To use simply draw the Dyne Test pen across the material surface, the liquid will either form a continuous film on the surface or draw back into droplets. If the Dyne test fluid remains as a film for 3 seconds or more then the material will have a minimum surface energy (Dyne level) in mN/m of that ink value. Should the Dyne test liquid draw back into droplets in less than 1 second then the surface energy (Dyne level) of the substrate is lower than that of the liquid value. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test pens.
