Technologies that impress

calvapro® corona and Plasma technology: efficient, environmentally-friendly, flexible and economic

With the calvapro® corona and plasma treatment, kalwar offers you gentle processes for optimising adhesion properties. Technologies that are 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 calvapro®- plasmatunnel and plascomized when treating complicated geometric shapes.


calvasol® process for Lab on Chip systems

With the patent pending calvasol® 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.


The calvasol® process is excellent for the hydrophilisation of Lab on Chip systems to optimise the fluidc properties.

The combination of our calvapro®plascolab system with the calvasol® funktionalisation offers you the maximum optimisation for your products. Hydrophile coats with long-term stability are, thus, no longer a challenge, regardless of the surface type involved. And if you require antistatic plastic surfaces with a bleeder resistance down to 108 Ohm, we can also handle that easily.

The advantages are obvious:

  • Reactive coat formation in the nano and sub-micro range
  • Cheaper balance-of-plant
  • Minimal consumption of reactive substances
  • Large selection of chemical components (of course also with FDA approval)
  • System set-up available in principle as explosion protection or clean room design.
  • Simple integration into production lines
  • Suitable both for research and industrial sectors
  • Use of process gases possible
