Varnishing / Coating
Coating pre-treatment
In order to achieve the highest possible quality when applying coats of paint, lacquer or varnish, a homogeneously thin coat must be applied to the surface in question. First, the surface is painted, rolled, sprayed or immersed. In a second step, solvents must evaporate in order to create a continuous, solid film consisting of binders, fillers, pigments, resins, etc.
The final degree of hardness and resistance can be enhanced by heat treatment or, for UV coatings, UV crosslinking. UV coatings take very little time to dry, and the resulting surfaces have excellent scratch resistance, no matter whether the finish is shiny or matte.
Dispersion coatings, also called water-based varnishes due to their high water content, are especially eco-friendly. They do not contain solvents, which create unpleasant smells, nor do they yellow over time.
Atmospheric plasma pre-treatment greatly enhances the wettability of the surfaces to be coated, especially so for materials which are difficult to wet such as plastic. It allows the varnish to spread homogeneously even when applied very thinly, resulting in fast drying times and faultless finishes. After drying and hardening, adhesion is greatly enhanced; this can be proven by a simple cross cutting test in which patterns are incised using a pre-defined adhesive tape.
