Download Audio File Here are a few theories to guide your decision making for achieving the thin coatings needed for filtration. Like with everything else in the coating world, membranes perform better the thinner they are. Thin coatings or castings, in this case, require a level of understanding in fluid [...]

Download Audio File Nonwovens, fabrics, papers and membranes provide unique substrates for fluid coating applications. Depending on the final product needs, the fluid may need to be placed on top of the substrate, penetrate all the way through the substrate or some arrangement of the fluid between these two [...]

Download Audio File The fundamentals of air entrainment, entrapment, and rheology are critical to product success. Water filtration is ubiquitous in our world. Water supplies need technological support to provide the volume necessary for our planet's population. There are five main types of filters that support water purification efforts [...]

Download Audio File When a slot die is coating a fluid, does it care which way it is pointed? No, it does not. So why are different terms utilized when the same piece of equipment is pointing up in the air, down towards the ground, or horizontally towards the [...]

Download Audio File If you are currently coating more than one layer of coating onto a substrate, you may want to consider the option of multi-layer coating. To provide more than one fluid at a time to a substrate, a pre-metered method like slot die coating is required. Slot [...]

Download Audio File Fluid coating is dependent on 5 main factors to have the precision required for today's coated products: the coating head, the positioning system for the coating head, the substrate uniformity, the backing roll tolerance, and the fluid delivery system. The fluid delivery system is a broad [...]

Download Audio File After a fluid is deposited onto a substrate anything can happen. While the fluid is balancing on the substrate and traveling to the curing section of the process, what will the fluid do? In this gap between the coating phenomena and the final cured state, the [...]

Download Audio File In Part 2 of this two-part series on intermittent or patch coating, fluid control and physical movement were investigated. EXPERIMENTAL Water-based anode and NMP-based cathode slurries were utilized with aluminum and copper substrates for coating understanding. These raw materials are typical for lithium-ion battery applications. Rheological [...]

Download Audio File Developing a product in the fluid coating industries requires determination of raw materials to provide for the differentiated features of the product, but equally important is the process development associated with turning these raw materials into an effectively and efficiently produced item. Whether you are looking [...]

Download Audio File ABSTRACT The world has gone patch coating crazy! Batteries, pharmaceuticals, even adhesives. The interest in reducing waste and providing functional coating that can be used right off the coating station is very high. With this increased interest in intermittent coating, we also have to consider the [...]
