At this year PaintExpo (Karlsruhe, April 8-11, 2014) Plasmatreat will demonstrate live (Hall 1, booth 1328) its high tech surface pretreatment method Openair®-Plasma.
The high tech surface pretreatment method Openair®-Plasma is used to create the most important prerequisite for optimal wetting of paints and coatings in order to obtain a homogeneous surface, long stable adhesion, thinner layer thicknesses and an immaculate paint gradient.
Visitors are welcome to bring their own substrate samples of no matter what material to the two "plasma bars". In a first live demonstration the sample's surface will undergo a fully automatic contact angle measurement by a PG-X Pocket Goniometer to determine the surface tension. The results are a reliable basis for the evaluation and control of various parameters, such as wettability, adhesion ability or surface contamination. The visitor can simply place the device on the surface of the object to be tested and press the button.
The internal pump dispenses a precisely metered droplet onto the test surface. The built-in camera takes a video sequence of the droplet and the results are presented as static contact angles or dynamic wetting and penetration functions.
Once the surface tension is determined the surface sample will be taken to the second plasma bar where by means of silkscreen printing the visitor can experience now the difference between a plasma-treated and an untreated coated
surface. Openair®-Plasma not only removes particles adhering to the surface but the treatment ensures at the same time that the object is electrostatically discharged.
Simultaneously the plasma activates the entire surface and creates ideal conditions for subsequent coating. The triple effect far outweighs the effectiveness of conventional systems. The specific and uniform surface tension achieved results in optimal distribution and uniform thickness of the subsequently applied paint layer as well as a long-time stable adhesion of the coating even under the most challenging load conditions.
