Coating Substrates and Substrate Interactions
Prior to the symposium, ISCST offers an outstanding continuing education course taught by leading industry experts. You can add this course to your conference registration or register for the short course only.
Standard Registration: $495 | Student Registration: $245
Omni William Penn Hotel, Pittsburgh, PA
Sunday, September 7, 8:30am – 4:00pm
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
- Solvent interactions
- Planarity
Who should attend
The course is intended for professionals actively involved in modeling or practicing coating and drying processes (including graduate students). The course materials are intended to be suitable for people with a B.S. degree in physical science or engineering.

Prof. Terry Blake was educated at Bristol University in the UK in the 1960s. During his PhD on enhanced oil recovery he developed the molecular-kinetic theory (MKT) of dynamic wetting – the first explanation of why the dynamic contact angle is velocity-dependent. Following postdoctoral research at the University of Texas and Imperial College London, he joined the Eastman Kodak laboratory in the UK, leading research on process technology and surface and colloid science. His own studies over more than 30 years have focused on dynamic wetting and high-speed coating methods, especially curtain coating. This work, in collaboration with colleagues in the UK and the USA, led to patents to increase coating speeds through control of solution rheology (which directly impacts dynamic wetting), substrate wettability and roughness. He is the author of some 60 papers on subjects including hydrodynamic and electrostatic assist of coating, wettability-directed pattern coating, the influence of surfactants on wetting and ink-jet printing. He has been a regular speaker at ISCST meetings and other international conferences. Since leaving Kodak, Terry has continued his research into fundamental aspects of dynamic wetting, working with academic colleagues at the Universities of Mons (where he is a visiting professor) and South Australia. He has taught courses on wetting at these institutions and the University of Bristol. He also acts as an independent industrial consultant.
Prof. Douglas W. Bousfield is a Professor in the Chemical and Biological Engineering Department at the University of Maine. Doug has been involved in paper coating and printing research for over 20 years. He is director of the University of Maine Paper Surface Science Program which is an academic-industry cooperation to promote research in the area of paper coating, sizing and printing. The Program has generated over 200 publications and presentations on topics such as particle motion during flow, coating flows, and ink-coating interactions.
Dr. E. J. (Ted) Lightfoot Has spent thirty years in the web coating, film casting and extrusion industries. He has worked in research, development, plant support (in both management and as an engineer), technical service (application development) and as a Six Sigma Black belt. He has worked on photographic film, fluoro-polymer films and coatings, optical coatings and laminated products. His background includes work in mixing, coating, drying, laminating, film orientation, melt extrusion and solvent extrusion. Currently, he is a Principal Investigator in DuPont’s Photovoltaic FluoroMaterials business.
