The Coating and Graphic Arts Committee brings you three industry experts to present three presentations on Tuesday, September 1st from 11AM – 1:45PM EST. These three presentations were queued for the C&GA track at PaperCon 2020 but will be presented virtually next week in this free event.
Attendance is free and open to everyone, but registration is required.
Q & A will follow!
Meet Presenter 1:
Tony Lyons, Ph.D.
Paper Lyons LLC.
Doctorate degree in Chemical Engineering from Lehigh University
Presentation: Advances in Coating Pigment Applications: Pigmented Aqueous Barrier Coatings
Tony Lyons will be discussing how the desire for more sustainable packaging has led to the development of fiber based packaging materials. Aqueous coatings are a pathway to improve the recyclability of these materials. Pigments used in these coatings can improve the performance of the coating and reduce cost while further improving the recyclability. Mineral Pigments are also considered to be compost neutral. This presentation will be a review of the pigments used in these barrier coatings. He will also provide examples of how the various pigments may perform in a barrier application.
Meet Presenter 2:
Ethan Glor, Ph.D.
Member of the Paper Coatings group at Dow
Doctorate degree in Chemistry from University of Pennsylvania
Presentation: The Use of Hollow Sphere Pigments as Strength Additives in Paper and Paperboard Coatings Part One: The Predictive Nature of Packing Models on Coating Properties
Ethan Glor will focus on the theory of bimodal spherical packing and demonstrate the predictive nature of packing models on the properties of coating systems containing Hollow Sphere Pigments (HSPs) of two different sizes. He will also examine conditions where the model fails by examining the effect of particle size on coating strength in systems.
Meet Presenter 3:
Brian Einsla, Ph.D.
Applications Scientist at Dow
Doctorate degree in Polymer Science and Engineering from Virginia Tech
Presentation: The Use of Hollow Sphere Pigments as Strength Additives in Paperboard Part 2: Optimization in Paperboard Formulations for Opacity and Strength
Brian will summarize the efforts in testing properties of coatings for paperboard by evaluating particle size and void fraction along with many coating parameters. This includes level of addition, binder chemistry and blends of two HSPs. Brian will also discuss his surprising finds using different binder chemistries.
