University of Wisconsin Stevens Point Courses

Advanced Paper Making: Additives

This course will be offered again in 2023 – please check back in early fall for dates

This two-day course provides an overview of common paper making additives used in the industry today. Clear descriptions of how and why these additives work are presented in classroom discussions. Attendees will participate in discussions focused on where additives are introduced into the paper making process, potential interactions with both equipment and other additives, and the relationship between additives and enhanced performance of paper.

This course features hands-on exercises on the UW-Stevens Point pilot paper machine where attendees will produce paper with different additives. The group will also evaluate the properties of this paper using typical laboratory tests.

The course runs from 8 a.m. to 4 p.m. daily with lunch and break refreshments included.

Class size is limited to 16 for this course to provide ample opportunities for questions and discussion during classroom sessions and hands-on experiences on the paper machine.

The Instructor

Dr. Gerry Ring is professor emeritus of paper science and engineering at the University of Wisconsin-Stevens Point. In 1980, Ring began his professional career as a Research Scientist for Kimberly-Clark Corporation after obtaining his Ph.D. at the Institute of Paper Chemistry in Appleton Wisconsin. In 1986, Ring joined the faculty of UW-Stevens Point and chaired its paper science (now paper science and engineering) program from 2003 until 2013.

Dr. Ring has written 15 publications, including editing the Colloid Chemistry of Papermaking Materials textbook. He holds four patents and was recognized in the 1994, 2000 and 2004 editions of Who’s Who Among America’s Teachers. He is also listed in the Marquis Who’s Who in America.  Ring received an Award for Excellence from the Wisconsin University Continuing Education Association, Region IV in 1999. Ring is a TAPPI Fellow, and a recipient of TAPPI Journal’s Best Research Paper for 2011. Ring’s research is in the area of paper physics emphasizing hydrogen bonding and sheet formation.
