Slot die coating viscosity range

By Author

Thus, slot die coating is an important ﬁlm fabrication method for applications where precise coating is required. The wet thickness of the coated liquid layer in the tradi-tional slot die coating process can vary from 10 to a few hun-dred microns and the coating speed can be as high as 2 m/s,3 while with a tensioned-web-over-slot die (TWOSD

SLOT-DIE HEADS | RESEARCH SERIES – FOM Technologies Our research series Slot-Die heads are a piece of state-of-the-art coating equipment. Each coating head has been designed to fulfil the need for professional Slot-Die coating components. Produced from some of the hardest steel in the world, the material undergoes meticulously proces-ses to provide stable and ultra-precise accuracy. Fixed Slot Dies & Coating Equipment - Slot Die Coating ... Slot Die Coating Technology . Slot coating is a “pre-metered” system that applies an adhesive or coating to the web at a constant rate and permits precise control over coat weight and the cross-web distribution. Unlike “post-metering” methods, a uniform operating pump delivers the exact volume of fluid to maintain the Precision Slot Die - mirwecfilm.com

Slot die coating enables even distribution of a pre-metered coating to be applied to a substrate. In many cases a slot die can increase productionWith a wide viscosity and speed range, excellent temperature control and coating thickness accuracy, slot die coaters are an extremely effective...

Thanks to intensive cooperation with world-leading slot-die manufacturers, KKA is able to provide precise coating on a variety of substrates. Depending on the properties of the product webs and the fluids used, an optimal coating result can be achieved by arranging the application head differently in the system.

Slot Die Coating Background The slot die coating process was invented by Beguin to coat gelatin Silver Halide layers for making photographic films [8]. The process can be used with a variety of organic and inorganic liquids and it can accommodate a wide range of fluid viscosities. The slot die coating process is Slot Die Coating - AIMCAL

•Both coating systems – gravure and curtain – have their limits •Gravure system covers a wide range in coat weight and viscosity •Curtain coating is limited in lower coat weights at lower speeds and in viscosity, but it is capable for higher speeds •Curtain coating needs adaptation in surface tension of compound
