Facilities Available for Use - Coating and Finishing
Coating a thin layer of material on the surface of paper, film, foil, or composites is a very effective method of adding functionality and value to a product. Printing papers, paper cups, grease-resistant food packaging, and high strength composites all benefit from quality coatings. The PDC routinely works with clients to improve product properties and lower costs by formulating and applying coatings to their products. We can test for printability on a new paper product, determine the effectiveness of barrier coatings, or evaluate fiber structure and interactions at the nano-scale. The PDC is pleased to work with you on any project, large or small. Resources available for your use include:
The PDC’s new Web Pilot Coater/Laminator is capable of processing paper directly from the PDC’s pilot paper machine or from commercial machines. Our customers now have full access to a complete, pilot scale facility that can process raw materials into a finished web product – all in one facility. The coater can process webs up to 12 inches in width at speeds of up to 100 fpm.
The Cylindrical Laboratory Coater (CLC 6000) provides an ideal means to evaluate coating formulations and substrates at commercial operating conditions. The CLC operates at speeds up to 6,000 fpm with pigmented coatings of up to 70% solids.
Expanded Pilot Coating Capability
The PDC has taken a great step forward with its new, expanded pilot coating capability. The new service includes an industrial scale, High-Speed Pilot Web Coater that offers a wide range of coating applications. This includes trailing blade or rod, speeds up to 4200 fpm, web width up to 28 inches, and in-line finishing capability.
Calendering improves the printing properties paper, and is controlled by base sheet moisture content, coating composition of coating, line speed, pressure and temperature. The PDC has an on-machine calender located prior to the reel of the paper machine, as well as an off-line, heated, soft-nip calender.
The PDC has a wide variety of print tests for paper and paperboard products, including a KRK Universal Printability Tester for testing of the pick, gloss and mottle and an IGT Printability Tester for evaluating surface strength.

Paper Surface Science Program
The Paper Surface Science Program (PSSP) is an industry consortium working under the direction of Dr. Douglas Bousfield. It seeks to develop fundamental and applied knowledge about paper surface treatment processes (sizing, coating, printing, gluing) and structure-performance relationships in manufactured products. Areas of research includes fluid-paper interactions in surface treatments and physics and chemistry of paper surfaces.
