Dr. J. Edward Glass to give first Honorary Wayne Kraus Lecture at Philadelphia Society meeting, January 12, 2005.

The Philadelphia Society for Coatings Technology (PSCT) has announced that Dr. J. Edward Glass will give the first annual Honorary Wayne Kraus Lecture at its upcoming meeting on January 12, 2006 at 3:00 pm. To be held at the Williamson Restaurant in Horsham, PA, the lecture will focus on "Influence of Components on the Rheology and Film Properties of Waterborne Coatings."

Wayne A. Kraus

The lecture commemorates the many contributions that Wayne Kraus has made to the Society. A member of the Society for over 25 years, Mr. Kraus is one of the founders of the Society's biennial Eastern Training Conference. He is credited with initiating a job search assistance program, implementing a multi-speaker format at technical meetings, and emphasizing the need for high quality, noncommercial presentations. President of PSCT in 1977, Mr. Kraus is the only member of the Society to win the prestigious Liberty Bell Award twice (1988 and 2001). This award recognizes "outstanding contributions to the advancement of the protective coatings industry and to the Philadelphia Society." He served as Society Representative on the FSCT Board of Directors from 1989-1995, and is one of only seven current Society Honorary Members.

Dr. J. Edward Glass

Regarded as one of the world's leading experts in the areas of water-soluble polymers and waterborne coatings, Dr. Glass was formerly associated with the Coatings and Polymers Department at North Dakota State University. In 2005, he received the Roy W. Tess Award from the Division of Polymeric Materials Science and Engineering of the American Chemical Society.

Dr. Glass has published over 175 papers, received six patents, and edited seven books. He has also presented numerous keynote lectures and plenary talks at national and international conferences including FSCT Annual Meeting Technical Programs, Gordon Conferences, European FATIPEC Conferences, and the Athens International Coatings Conference.

According to Dr. Glass, coatings rheology has been an obsession for many over the past century, since "optimized rheology" can bring improved applied coatings performance. However, in many cases, improved coating film properties arise without changes in rheology. Unlike high solids or UV coatings, waterborne latex coatings are non-Newtonian fluids and elastic properties of the fluids (storage modulus, first normal stress difference) can override "viscosity" in defining the flowout of applied fluids.

In his presentation, Dr. Glass will discuss the general relationships among elastic functions in the flow of fluids and how they are influenced by the components of a latex coating. The influence of latex, thickener, coalescing aid, dispersant, hiding pigment compositions, fillers, colorants, and surfactants on film properties applied by a variety of processes will be presented. The application processes will include brush, roll velocity and gap openings, and spray applications with different nozzle geometries.
