Film Split Defects
Download Audio File When there are two rolling surfaces moving in the same direction, the fluid needs to decide which surface to follow. But how is this decision made? [...]
Looking Behind the Curtain of Coating
Download Audio File Economies of scale occur when a coated product is manufactured wide, fast and in one pass. Substrates can be manufactured wide and multilayer coating can provided [...]
The Effects of Viscoelastic Behavior
Download Audio File When coating a fluid, consideration of the rubbery behavior needs to be considered with the shear rate versus viscosity data. Coating rubber bands is not easy. [...]
Conflicting Flow in Coating
Download Audio File Coating with a self-metered system is a study of flow dynamics where we are fighting viscous forces. Depending on where the math is being applied, one [...]
Stepwise Process Fluid Coating
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 [...]
Fighting Viscous Forces to Improve Fluid Coating Success
Download Audio File When it comes to slot die fluid coating, the mathematical equations that dictate flow are fundamental, but the details are complicated. The goal with understanding the [...]
Particles in Fluid Coating
Download Audio File With the modern coating era upon us, the need to coat functional materials has grown exponentially. Whether you are looking to coat flexible electronics, solar panels, [...]
Stop Defects Before They Start
Download Audio File One of the best ways to not have defects in fluid coating isn't a trick with a pump or a tip with a coating head. Reducing [...]
Streak Formation
Download Audio File Streak defects are one of the most common coating defects in roll-to-roll coating. They are also very elusive! How streaks are formed and progress is a [...]
Agglomerates
Download Audio File Agglomeration is a dispersion issue that can cause headaches for coating operators. Fundamentally, an agglomerate is a collection of particles that stick together and create a larger [...]
