To avoid having to scrap large quantities of substrate with a poor print due to insufficient bonding it is always advisable to check the corona treated material before processing. Using a felt tip dyne pen is an easy and inexpensive way to check if a substrate is ready for processing.

Benefits:

• Reduces production of scrap material
• Quick and reliable test results
• Easy to use
• Inexpensive method
• 3 months durability of dyne pen

How to measure surface tension using dyne pens

The test is carried out by simply running the dyne pen across the material to be processed, producing a line. If the line is continuous, the dyne level is correct – if the line breaks into droplets, the dyne level is incorrect and the surface tension will not be suitable for printing, coating, or laminating.

On a partially treated substrate the ink can also be used to indicate if the correct areas were treated.

Our dyne pens are supplied in dyne value range from 32 to 56 dyne/cm in steps of 2 dyne. They can be purchased singly or in packs of 8 in dyne levels of your choice and come with full instructions.
