La energía superficial es un parámetro muy importante para los sustratos que deben tratarse en procesos como el pegado, el barnizado o la impresión.

Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called «activation“ in plasma technology.

Through a simple measurement of the surface energy, the activation capacity of a surface treatment may be evaluated and quantified. This allows for a quantitative comparison of the performance and efficiency of various methods of surface treatment using a physically defined quantity.

PDD® Plasma technology improves surface texture and wettability. It is suitable for integration into 3D printers of all kinds and categories of performance.

The new nozzles for piezobrush PZ2 enable applications which were not possible with the standard version of this product.
