Mark’s first introduction to the world of slot die coating was in 1996, when he was learning the technology at 3M. Today, Mark and Tim Marion own and operate Coating Tech Slot Dies, which supplies precision coating equipment. In addition, CTSD provides education and consultation for improved coating efficiencies and increased coating capability.
Slot die coating systems can transcend limitations of conventional roll coating. Slot die coating emerges as an efficient, controllable alternative to roll coating and other conventional methods of applying fluids to web substrates. For a wide range of adhesives and low-viscosity coatings, today’s market and regulatory forces place a high ... The e ect of shear-thickening on the stability of slot-die ... with a similar viscosity Newtonian case to understand the importance of complex rheology for these high viscosity liquids. Methods and Materials Experimental setup The slot-die coating experiments were performed on a custom-built lab-scale slot-die coater. The schematic of the slot-die coating experimental set-up is shown in Figure1. Fixed Slot Dies & Coating Equipment - Slot Die Coating ... Slot Die Coating Technology . Slot coating is a “pre-metered” system that applies an adhesive or coating to the web at a constant rate and permits precise control over coat weight and the cross-web distribution. Unlike “post-metering” methods, a uniform operating pump delivers the exact volume of fluid to maintain the Publications | PTFP Group “The Mechanism of Air Entrainment in the Slot Die Coating Process,” The 16 th International Coating Science and Technology Symposium, Atlanta, GA, September 2012.
