Product Description

The plastic processing industries have numerous applications for XLC anti-adhesion surface treatments. Avoiding deposits on extrusion or die-casting tools not only reduces cleaning and maintenance costs, but also significantly improves productivity and product quality.

In the pharmaceutical industry, anti-adhesion coatings on press tools were applied successfully over many years in industrial use. By using SDLC coated tablet tools, the adhesion of strongly sticking powder mixtures can be completely avoided without any additional use of release-agents.

The additional anti-foiling effect of the layer system reduces or even prevents lime deposits. Due to the relatively low process temperatures of only approx. 100 °C during the Plasma Assisted Chemical Vapor Deposition (PACVD)  process, theses coatings are suitable for further applications e. g. for temperature sensitive non-metallic tools and components. In addition the feasibility to adjust the coating property profile of modified SDLC coatings in a wide range, numerous further applications are possible, e. g. from easy-to-clean surfaces to electrical isolating purposes and highly corrosion resisitant applications.
