Measure the surface energy of your materials
Plastics that have low surface tensions (below 40 dynes/cm) generally cannot be adhered to easily. Surface tensions must be at least 38 - 42 dynes/cm to realize good adhesion. With a treatment of Openair® plasma, surface tensions of over 70 dynes/cm can be achieved at which point water
will moisten the surface completely and not bead. The higher the dyne
level, the more robust the adhesive process becomes.
When you are faced with a bonding problem, an excellent diagnostic tool to help identify the magnitude of the problem is to measure the surface energy of the material. A common method is a dyne pen that dispenses a fluid of known surface tension. However, repeated contact with surfaces can cause these pens to pick up contaminants from the surfaces that, as they accumulate, result in erroneous data.
Plasmatreat Dyne Test Inks are a proven tool for measuring surface energies and come conveniently packed in kits or they are available individually. The kits are available in 7 and 22 bottle sets. We offer both Methanol (standard) and Ethanol (non-toxic) formulas in glass bottles with applicator brush.
Testing is easy to perform and interpret by following the instructions provided in each kit.
Once you have determined the surface tension of the material it makes it easier to discuss the best ways to optimize your production processes.
