With the corona treatment, kalwar offers you a gentle process for optimising adhesion properties. A technology that is more efficient, more environmentally-friendly, more flexible and more economic than other options. Treatment of material surfaces using the corona process is effected using extremely fast high-voltage discharges on electrodes, between which we place the film, profile or mould. The ionisation is caused by the energy discharged when oxygen and nitrogen molecules collide in the air. The existing atomic oxygen influences various adhesion mechanisms in and on the material surface, which facilitate subsequent processing of the material. The type of adhesion mechanism is dependent on the treatment climate and the material. The adhesion value is governed by the corona energy level, the treatment time and climate, and the material itself.

We achieve optimum results with our CORLINE system when treating complicated geometric shapes. Bei der Behandlung von geometrisch komplizierten Formen erzielen wir mit unserem CORLINE System optimale Erfolge.

With the patented corona aerosol process kalwar offers you the evolutionary development of the corona treatment. It is now possible to combine the cost-effective inline application of corona surface modification with the quality and surface characteristics of cost-intensive offline methods. The system principle is both simple and logical. Instead of two production steps - pretreatment then coating - we have simply combined both processes. And without requiring complicated plant technology, e.g. low-pressure plasma.
