Surface treatment
Our surface treatement solutions:
Corona pretreatments
Corona pretreatments have been used for decades to achieve a reliable adhesion of printing inks, varnishes, glues and even coatings. In particular strip materials such as plastic film, aluminium foil, paper and non-wovens are functionalised in this way.
There are inventive solutions available for thicker materials and 3-dimensional products. An extensive range of diverse configurations allows the best solution to be found every time.
Depending on the nature of the material to be treated, different types of electrodes and basic rollers can be selected. Ceramic, metal and quartz electrodes form part of the standard range.
Some applications are:
- Corona for plate materials
- Corona for narrow strips
- Corona for cable applications
- Corona for 3D materials
Plasma pretreatments
Atmospheric plasma has been used since the mid-90’s as the most significant innovation within the world of adhesion problems. Thanks to a very intensive and homogeneous treatment, plastics, metals, glass and ceramic surfaces can be treated in a very efficient way, resulting in durable adhesion. Atmospheric plasma can be used not only for cleaning and activating, it is also an option for the application of functional coatings.
Plasmatreat is the global market leader and leading innovator in this field. Thanks to this technology, hundreds of widely varying adhesion problems have been solved, each time with economic and technical feasibility.
Some of the applications of this are:
- Gluing of headlamps, door seals, gluing of windscreens
- Cleaning and activation of printed circuit boards prior to casting
- Gluing of paper seal on food packaging
- Gluing and printing of cooking plates

Pre-treatment
Coating
Activating and coating a material in one step. Precursor material is applied directly.
Activating
The determination of surface tension using test inks shows that: When surface tension is low no wetting is possible; following activation by Plasmatreat’s Openair® plasma the whole surface can be wetted.
Cleaning
Cleaning a surface to the depth of its pores by means of Plasmatreat’s Openair® plasma. No mechanical damage to the surface, no wet chemicals and it is an environmentally friendly process.
