Dyne Test Pens are non-toxic and are used by operators that handle the production lines to check if a material has been treated, or not.
The measurements is made accordingly to the same ASTM procedure as the test inks, so it verifies if the liquid remains spread for at least TWO SECONDS.
Value of reference: 38 dynes / cm.
Instructions for use
Spread a thin layer of solution by drawing with the pen a line of about 5 cm on the media to be measured.
- If the solution remains anchored, support is treated.
- If the solution does not remain anchored and is divided into droplets, support is not treated.
