Technical Infrastructure Surface Technology

Skip breadcrumb navigation

Several technological plants are available for our partners and customers, for instance for various plasma processes, fluorination and flaming to be used for the targeted modification or functionalisation of material surfaces. Thus, barrier coating and wear-protection coating in nanometre scale can be generated, adhesion can be improved by incorporation of functional groups, as well as the hydrophobic and hydrophilic behaviour of surfaces. These processes are typically applied for medical products, food packaging, flexible light-emitting diodes and solar cells as well as for producing leather, films and coated textiles.

MATERIAL CHARACTERISATION TESTS

MATERIAL CHARACTERISATION TESTS

For the characterisation of material surfaces test instruments will be available which can be used to determine the relevant properties, partly pursuant to established norms and standards.

Range of tests

  • Wetting behaviour (contact angle, surface energy)

  • Surface topographies (roughness 2D/3D, grain depth measurement)

  • Adhesions

  • Migration investigations

  • Rheological tests

  • Scratch resistance

  • Coating thickness determination

  • Analysis of elements/bonding to material surface

  • Deformation (viscoelastic behaviour, creep behaviour)

  • Damping

  • Bending

  • Contact pressure distribution

  • Thermal conductivity
