An Example of Coating a Rough and Porous Substrat

Prof. Terry Blake, Universities of Mons
Prof. Douglas W. Bousfield, University of Maine
Dr. E. J. (Ted) Lightfoot, DuPont

Most heuristic flowcharts for selecting a coating technique begin with characteristics of the substrate This course moves beyond the heuristics to discuss how the properties of the substrate (listed below) impact the selection of coating and drying techniques for a given substrate and the selection of substrates for a given process.

Mechanical properties:

  • Surface roughness
  • Porosity
  • Surface treatment (including cleaning)
  • Static and dynamic wetting (including electrostatic assist)
  • Composition
  • Planarity
