Roller Geometry-What is your Roller's True Shape  |  Posted: August 11th, 2017
How does a roller's shape influence a coated product and coating defects? The variation of a roller's geometry can produce many web handling problems. Roller geometry directly affects the way a web is handled through a machine. Common roll tolerances… Read more »

Balancing Slot Die Design  |  Posted: July 18th, 2017
Wouldn't life be great if complex things could be reduced to simple functions? In the world of coating, if you look deep enough, you can find some of these useful nuggets. In self-metered coating, the liquid flow can be studied as a collection of bulk… Read more »

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 »
