What is Slot Die Coating?

Slot Die Coating is the standard for thin accuracy in the web handling industry. These rolls offer uniformity and quality as well as pre-metering of the liquid coating to ensure it is all applied to the substrate. This process can range from thick coating down to micron-measured.

Advantages include:

  • Closed system
  • Maintained temperature
  • Uniformly distributed fluid
  • Defined coat width
  • Increased production speeds
  • Positive coat weight control
