PaperCon Coating and Graphic Arts Program
Program Chair - Jeff Lange, Bercen
The Coating program for 2012 will address the hottest trends in the coating of paper and board grades, including the emergence of curtain coating. In addition, you can join the Hagemeyer Happy Hour, a great tradition that provides the opportunity to discuss these hot areas in a fun, casual environment. Come network with the world class experts in paper coating.
Coating Best Papers I & II – Strength Properties, Curtain Coating and Synthetic Binders
Session Chairs: Femi O. Kotoye, Styron LLC, Steven Bloembergen, Ecosynthetix Inc.
Today’s best science in coating will be presented in two interesting sessions. The papers will focus on the influence of the coating process on strength properties of coated materials as well as application methods for packaging grades. Attendees will also learn about advances in synthetic binder technology for coated paperboard and fundamental and practical new developments in curtain coating and wet & dry strength properties of paper coatings. Implementation of a commercial curtain coater for double coated wood-free fine paper in Asia is also featured.
Advances in Coating and Drying Technology
Session Chair: Prakash Malla, Thiele Kaolin
Non-impact coating technology such as curtain coating is finding its way from specialty to mainstream coated grades. In this session, new advances will be discussed which allow use of curtain coating for board and packaging grades with improved productivity and quality. Earlier limitationsof the curtain coater can be overcome by making appropriate changes in coating color chemistry. Improvements in the coating color circulation loop which can improve runnabiltiy and paper quality will also be presented. Energy saving practices in coating drying will also be explored.
Fundamentals of Coating Strength and New Test Methods
Session Chair: Greg Welsch, Styron LLC
Fundamentals of paper coating strength will be investigated by ooking at a predictive model for strength development in model paper coating structures. This is followed by separate work investigating the critical parameters of synthetic latexes than can affect particle adhesion within the coating structure. In the second part of this session, creative thinking has led to the development of two new tests to tackle the challenges found in measuring coating brightness due to the changes in observer angle and the use of optical brightening agents as well as a separate test method for predicting tail edge picking on offset printing presses.
Growing Trends in Calendering
Session Chair: Bill Frawley
In this session you will learn why pre and post calendering enhance curtain coated grades, how real-time sensors can harvest profits from your multi nipped in calender rolls, and how metal belt calendering of uncoated wood-free paper can improve bulk with less fiber and higher filler content.
