Coating Matters

Stepwise Process Fluid Coating

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?

Coating Matters | Patch Coating for Precision Fluid Placement, Pt. 2

Intermittent coating continues to be a growing field in the world of slot die coating technology in general, and the flexible electronics and energy storage industries in particular.

Optimization of Fluid Coating

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 to develop an improved tape, label, battery, or optical film, understanding and optimizing the coating process is important. The larger this coating window the more latitude there is for success.

The world has gone patch coating crazy! Batteries, pharmaceuticals, even adhesives. With increased interest in intermittent coating, we have to consider the technical challenges

Fighting Viscous Forces to Improve Fluid Coating Success

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 math should be not to make things more complicated, but to simplify the understanding and lead engineers and operators towards common controls for adjusting at the coating line. So let’s do just that…
