Dieter Braun GmbH reports about their expierience with plasma treatment of cables and wires before moulding and encapsulation.
The surface energy determines how much energy is needed to break the chemical bonds when a new surface of a solid or liquid is created. Surface energy is used to describe wettability. This is particularly important when materials such as plastic are to be bonded, painted or printed. If a surface is highly energetic (polar), the adhesion of printing inks or adhesives to it is considerably higher than with low-energy (non-polar) surfaces. For liquids, the surface energy is equal to the surface tension. It’s quite easy to increase surface energy with plasma technology.
Surface energy Determination of surface energy by means of test inks and contact angle measurement, enhancement through plasma treatment Wettability is of major importance for all kinds of surface treatments like printing, varnishing and gluing. It describes the behaviour of liquids on solid surfaces which is dependent on the surface tension of the liquid and […]
