Dyne test pens

Dyne test pens are used to measure the surface energy of a material by testing its ability to hold a liquid droplet. Here are the steps to use a dyne test pen:

1. Select the appropriate dyne level pen: Dyne test pens are available in different dyne levels, ranging from 30 to 60. Choose a pen that matches the expected surface energy of the material being tested.
2. Clean the surface: Clean the surface of the material being tested to remove any contaminants such as dust, oil, or grease. This will ensure that the test results are accurate.
3. Apply the pen: Uncap the dyne test pen and apply a small amount of the pen’s liquid on the surface of the material being tested. Use a steady hand to apply the liquid in a straight line.
4. Observe the results: Watch the droplet of liquid closely. If the droplet beads up and rolls off the surface, it means the surface energy is lower than the dyne level of the pen. If the droplet spreads out and wets the surface, the surface energy is higher than the dyne level of the pen.
5. Record the results: Record the dyne level of the pen that gives the first indication of wetting. For example, if a 42 dyne pen is the first to wet the surface, then the surface energy is 42 dynes/cm.

Note that dyne test pens should be used in a controlled environment to ensure accurate results. The temperature and humidity of the environment can affect the test results, so it’s important to follow the manufacturer’s instructions carefully.
