This year’s educational program offers top subject matter designed and executed by experts in the glass industry. Learn how to bring in big business at Glass Expo Northeast™ ’19, taking place March 27-28, 2019.

Paul Düffer, technical adjunct to the Glass Committee of the International Window Cleaning Association (IWCA), will examine the “Unique Vulnerabilities of Glass at Construction Sites (1 AIA LU)” on Thursday, March 28 from 10–11 a.m.

Attendees of this seminar will receive insights related to the underlying causes of commonly observed forms of soiling and damage to the surfaces of newly installed glazing units. The tenacity of concrete runoff and hard water spotting is addressed, along with the phenomena of condensation “ghosts” and tin surface etch haze. This presentation also explains how poor storage and handling practices can lead to serious damage from glass surface corrosion. Come see first-hand problems associated with the removal of concrete and mortar deposits from glass as well as metallic grinding dust and welding debris. Walk away with an understanding of the unique problems associated with post-construction window cleaning and share the education with your team.

“Unique Vulnerabilities of Glass at Construction Sites (1 AIA LU)”
Presented by Paul Düffer, technical adjunct to the Glass Committee of IWCA
Thursday, March 28 from 10 – 11 a.m.

Paul Düffer, Ph. D., earned a Bachelor of Science degree in chemistry, and M.S. and Ph.D. degrees in the field of physical chemistry. Dr. Düffer joined PPG Industries in Pittsburgh at its Glass Research and Development Center as a senior research chemist. During the ensuing years, he was promoted to the positions of research associate and senior research associate. Subsequent endeavors focused on addressing problems associated with glass surface corrosion and the preservation of glass surface quality during transport and storage. Düffer holds nine patents in the U.S. and several foreign patents in the area of glass interleaving materials and anti-corrosive packaging systems.

Paul has written a number of articles that address the practical aspects of glass surface behavior which have appeared in various trade publications and conference proceedings. Topics addressed have included the history of glass interleaving technology, glass storage and prevention of surface corrosion, corrosion phenomena and fine crystal glass, concrete run-off on glass, the impact of hard water spots on glass surface quality as well as the interaction of construction materials and glass surfaces. In April of 2008, he was awarded the Frank S. Child Award from the Society of Glass and Ceramic Decorators for outstanding technical contributions to the glass manufacturing and decorating industries.

Düffer retired from PPG Industries after 31 years of service and currently engages in developing seminar programs and educational material in order to promote a general awareness of the practical aspects of glass surface properties as well as acting as technical adjunct to the Glass Committee of IWCA.
