PVN Dyne Pen (Redish Pink)

PVN Dyne Testing Solutions
Application & USE
  • In a dyne test, wetting tension liquids are spread over a film surface to determine printability, coating laydown, and heat salability 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.
  • Dyne Testing 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.

  • Dyne Test Pens are available in a range of values from 30 to 72 Dynes/cm (mN/m) and are supplied in disposable pens. The test fluid contained within the pens is to ISO 8296 with additional high visibility dye for easy readings.
