Almost a natural law: Perfect surfaces need perfect preparation.

Corona treatment: the material surface is altered by electrical loading to improve adhesion. Different types of corona electrodes enable us to treat a large range of materials. A simple, but extremely effective process.

As a specialist in corona treatment, kalwar has perfected this principle and developed a second variant: corona aerosol coating (calvasol).
Substances are applied to the material surface through the corona field using aerosolisation, such as antistatic or barrier substances that attach to the surface.

We're happy to give you more information about kalwar's unique know-how with the corona treatment.
