Presented by Dr. Charles A. Bishop, C.A.Bishop Consulting Ltd. There has been plenty of publicity about the rapid increase in the price of Indium. This price rise was as a result of a number of factors such as it only being mined as a byproduct of zinc (1)
Troubleshooting Web-Handling Problems and Dryer Related Coating Defects Inside Flotation Dryers Paid Members Public
Presented by Dan Bemi & Steve Zagar, MEGTEC Systems For many converting operations, a flotation drying system represents the longest web span between tension isolation points on the entire coating line. As such, web stability inside the dryer can be a concern. Current trends toward faster line speeds and lighter
Sensing and Control of Vacuum Processes Presented by Dermot Monaghan Paid Members Public
What You Will Learn: The sensing and control of the vacuum coating process is of upmost importance for consistent, high-quality end-product. Every process will at least have one pressure gauge and some will make use of a Residual Gas Analyser (RGA) to monitor the condition of the base vacuum before

Surfactant Considerations for Successful Multilayer Coating Paid Members Public
Presented by Bill Devine, Carestream Health, Inc. Optimization of surface tension is critical to successful multilayer coating. Surfactants (surface-active agents) lower surface tension (energy) at immiscible interfaces by their dual hydrophilic and hydrophobic nature. This property makes them valuable as additives to coating formulations to perform a variety of functions
