Dispersions in Liquid Coating | Posted: June 19th, 2017
Liquids can be described as mayonnaise or beer. The Newtonian fluids are beer - they are self-leveling and if you turn a glass of beer upside down, the beer spills out. The non-Newtonian fluids are mayonnaise - without shear they will not… Read more »
The Critical Variable - Slot Die Lip Gap | Posted: May 25th, 2017
It's important to pay attention to critical variables in coating. When it comes to slot die setup and operation, the variables can be separated into linear variables and cubic variables. As you can imagine, linear variables affect the coating performance… Read more »
