Dyne pen for ink

The Dyne pen applies a test liquid with a known surface tension through its tip and observes whether the liquid contracts or spreads on the material's surface to determine its wettability. It is used for quickly detecting the effectiveness of surface treatments on substrates such as plastics and metals, guiding adjustments in ink and coating adhesion.
Selection
Select the pen model based on the common surface tension range of the material being tested. For example, choose the 30-40 mN/m series for plastics. During actual testing, start with pens of lower tension values and select the critical pen type that allows the test liquid to spread continuously without shrinking. Verify that the material's process requirements match the labeled tension value of the pen.
