RHEOLOGY & SLOT DIE COATING TECHNOLOGY - PSTC 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 ... 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.

The slot die is perfect for uniform film coating of 1 micron and up to 300-micron thickness.Attention: The final coating thickness is dependent on a wide range of parameters such as slurry viscosity, solid particle size, solid content, shim thickness, foil rolling speed and slurry feeding rate.
Slot die coating is a processing technique for the deposition of homogeneous wet films. It is usually used to coat large areas or stripes with highHomogeneous films with high uniformity. Applicable to roll-to-roll processing. Broad range of viscosities (from < 1 mPa⋅s to several thousand Pa⋅s). Slot Coating - an overview | ScienceDirect Topics | Slot… The coating quality and the coating weight uniformity in the slot die are a function of die design and die geometry.Because the viscosity is relatively low, the pressures within the die are also relatively low and the die can be much less massive than an extrusion die that works with very high viscosity...
