About
Dyne pens, sometimes known as corona test pens, are a quick and easy means to verify if a substrate has sufficient surface tension for applications like printing, laminating or vacuum metallizing. These dyne pens allow you to effectively control the quality of the material after corona surface treatment, significantly reducing the loss caused by insufficiently treated materials.
Usage
Using dyne pen to simply draw a line over the surface of the material to be tested, if the line is solid and does not shrink, that means you have achieved correct dyne level. If the line shrinks and breaks into droplets within 2 seconds, then the dyne level is incorrect. The actual surface tension of material surface can be measured by applying dyne pens of different values.
Additional Notes / Tips
- Dyne pens come in different dyne values (e.g., 30, 36, 42 dynes) to test a range of surface energies.
- Always use a clean, dust-free surface for accurate testing.
- Store pens capped and in a cool, dry place to prevent drying out.
- They are widely used in flexible packaging, plastic films, labels, and other industrial surfaces where adhesion quality is critical.
- Some pens use quick-drying ink while others may be solvent-based, depending on the substrate type.
