Expert has expertise in slot coating and slide coating. He has given seminars on coating and drying at a number of client companies. Topics include premetered coating, roll coating, coating die design, fluid preparation, surface forces in coating, limits of coatability, hydrodynamic instabilities, drying, coating and drying defects, and static electricity. He organized the coating and the coating defects courses at the biennial AIChE Coating Symposia (he organized the first symposium). He gives the coating course in alternate years at the University of Minnesota. He has co-authored several publications on coating defects and technology. He is also knowledgeable in curtain coating, gravure coating, reverse and forward roll coating, Mayer rod coating, dip coating, and fiber and wire coating.

For solvent and aqueous coatings on continuous webs, Expert developed spreadsheets to predict the temperatures and solvent levels in the coating throughout the constant and falling rate periods, including the initial transients. The spreadsheets can handle mixed solvents and infra-red heaters, and are for both single-sided and flotation dryers. They are successfully used by clients. In addition, he gives seminars on drying.


Expert co-authored a book on the application of coating chemicals. He has taught many company courses and has given seminars on statistical design and analysis of experiments, including Taguchi designs. He applies these techniques to his work on coating and drying.


Expert has designed coating dies for several clients to obtain uniform coverage across the width of the web. He published two papers on die design. These methods are applicable to the internal design of slot, slide, and curtain coating dies.

Expert designed slot coating dies to give very uniform flow across the web. He designed, helped run, and analyzed factorial experiments that showed clients the optimum conditions for slot coating of magnetic media and for gravure coating. Expert explained causes of a serious coating defect and showed a client how to eliminate the defect by slight changes in the coating die. He explained to clients the causes of skinning during drying, and how to avoid it. Expert presented half- and full-day seminars on coating and drying.

Expert may consult nationally and internationally, and is also local to the following cities: Boston, Massachusetts - Worcester, Massachusetts - Springfield, Massachusetts - Lowell, Massachusetts - Cambridge, Massachusetts - Brockton, Massachusetts - New Bedford, Massachusetts - Hartford, Connecticut - Manchester, New Hampshire - Providence, Rhode Island

Work History

Years Employer Title Department Responsibilities
Years: 1988 to Present Employer: Undisclosed Title: Independent Consultant Department: Responsibilities: Expert has helped clients get started in slot coating and gravure coating; designed coating dies; developed drying spreadsheets; and teaches seminars on coating and drying technology.
Years: 1981 to Present Employer: Undisclosed Title: Part-Time Lecturer & Adjunct Professor Department: Responsibilities: He taught graduate chemical engineering courses in fluid mechanics, chemical engineering mathematics, and separation processes; he also taught some undergraduate courses.
Years: 1960 to 1988 Employer: Polaroid Corp. Title: Senior Principal Engineer Department: R&D Responsibilities: Expert shortened time to production by developing an understanding of wave instabilites in multi-layer coatings. He suggested ways to coat thinner and faster.
He developed an improved coating die for off-the-roll coatings. He modeled the drying of photographic coatings to predict Expert point. He managed a pilot emulsion and dye dispersion facility during design, construction, and start-up, resulting in on-time start-up with high yields of quality products.
Years: 1958 to 1960 Employer: Ionics, Inc. Title: Senior Chemical Engineer Department: Responsibilities: He designed and built a pilot facility to test anodic protection of materials for ship hulls, and developed a laboratory-scale fluidized bed to make barium carbide.
Years: 1955 to 1958 Employer: Brown Co. Title: Senior Process Engineer Department: R&D, and later Pulp Production Responsibilities: He worked with a consulting engineer on the design of a recovery system for the sulfite pulp mill.
