Coating

The Coating department focuses on three key areas:

Powder coating
Wet painting
Inkjet and screen printing

Here, both coating systems and inks are developed and tested for their applicability and layer and surface properties. Particular attention is paid to functional coatings (e.g., electrically conductive, superhydrophobic, scratch-resistant) and innovative inkjet applications.

Paint and ink properties to be examined:

Viscosity and surface tension
Particle size and stability
Compatibility with different substrates

Coating properties to be investigated:

Adhesion strength
Coating thickness
Defects (holes, orange peel)

Surface properties

Surface tension (contact angle)
Electrical conductivity
Roughness
Haptics
Scratch resistance
Wash and scrub resistance
