Quick, Easy, Low-Cost Surface Measurement Technology

Key Takeaways

• Dyne Pens and Inks provide a quick, easy, and low-cost method for measuring surface energy and wettability of polymers.
• The Dyne Pen test is a simple, ISO- and ASTM-compliant method for determining surface energy of polymer-based materials.
• Dyne Pens are available in a range of values from 30 to 72 "Dynes" and can be used to inform surface preparation needs.

Introduction to Surface Measurement Technology

Measuring surface energy is crucial in various industries, including packaging and converting, automotive, aerospace, medical device manufacturing, and battery technology. Dyne Testing, an Intertronics company, offers a convenient solution with their Dyne Pens and Inks. These tools enable engineers and researchers to quickly and easily measure the surface energy of polymers, identifying potential issues with bonding, coating, painting, or printing.

The Dyne Pen Test Method

The Dyne Pen test is a straightforward method that complies with ISO 8296 and ASTM D2578-84 standards. To perform the test, the user selects a pen with a specific "Dyne" value, ranging from 30 to 72, and draws a line on the substrate. The test ink will either form a continuous film or draw back into droplets. If the ink stays as a film for 3 seconds or more, the substrate's minimum surface energy is lower than the test ink. This information helps determine the surface energy of the substrate, measured in mJ/m², mN/m, or dyne/cm.
