slot die coating

Slot-die coating is a coating technique for the application of solution, slurry, or extruded thin films onto typically flat substrates such as glass, metal, paper, fabric or plastic foils. The process was first developed for the industrial production of photographic papers in the 1950's. [1] Learn how slot die coating is a versatile and uniform deposition technique for various substrates and solutions. Find out how to optimize the slot die geometry, flow rate, solution viscosity, and substrate position to achieve high-quality coatings with Ossila's Slot Die Coater. Learn about the different types of slot-die coating systems by FOM Technologies, a leading manufacturer of inert gas-based equipment for thin film deposition. Find out how to integrate your slot-die coating process into a glovebox and use it for various applications such as OPVs, batteries, OLEDs, and more. Slot die coating technology provides this accurate and metered technology in a closed process for better control. Here is a summary of the extent of capability of a slot die (for typical coating fluids): Line speeds | 1-600 mpm Wet thickness coated | 1-2,000 microns Viscosity of fluid | 1-100,000 cP Accuracy | ±1% Slot die coating is a versatile process that is widely used for producing thin and uniform films. It was invented by Beguin1 for the production of photographic films and papers. During the conventional slot die coating process, a liquid is delivered through a fixed slot gap onto a moving substrate, filling the In premetered slot or extrusion coating and related sheet coating, a “bead” of liquid is held between the coating die and the moving sheet by capillary forces, which depend on gap clearances ...

Slot-die coating is a highly scalable technique for rapidly depositing thin and uniform films with minimal material waste and low operational cost. slot-die coating technology is used to deposit a variety of liquid chemistries onto substrates of various materials such as glass, metal, and polymers. In this manuscript, a method to reduce superelevations of lateral edges in cross-web direction during slot die coating of shear-thinning slurries for Li-ion battery electrodes (LIB) was developed. Therefore, the impact of the inner slot die geometry on the edge elevations was investigated. These elevations of the coating could be almost eliminated by optimizing the flow profile at the outlet ... Slot die coating is applied to deposit thin and homogenous films in roll-to-roll and sheet-to-sheet applications. The critical step in operation is to choose suitable process parameters within the process window. In this work, we investigate an upper limit for stripe coatings. This maximum film thickness is characterized by stripe merging which needs to be avoided in a stable process. It is ... Slot-die coating, invented in 1951, is a pre-metered process for the deposition of thin and uniform films 69. A slot-die coater is generally composed of a slot-die head with an upstream die ... coating dies have a fixed upstream lip length there is a maximum vacuum that can be applied before the upstream bead becomes too long and invades the vacuum box – weeping premetering is lost the range of vacuum over which slot coater can be operated gives defines the coating window
