The piezobrush PZ3 can be used efficiently in rocket development. Space Team Aachen uses it for the pre-treatment of carbon fibre reinforced plastic and aluminium interfaces.
If a surface is functionalized with plasma before bonding, the resulting bondings show a significant improvement in adhesion. Plasma can be used on a variety of materials: Metals, glass, ceramics and even natural materials such as wood and textiles react very well to plasma functionalization. For some of our customers, it is particularly important that many polymers with typical “non-stick” surfaces can be successfully bonded after plasma treatment through adhesion improvement.
The highlight of this year’s trade show appearance at Bondexpo is the presentation of the compact integration solution piezobrush® PZ3-i for the first time ever. The cold plasma device is designed for integration into existing production lines and is therefore compact, safe, and efficient. Thus, it is ideally suited for pre-treatment prior to gluing, printing, and laminating.
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.
