Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
InovisCoat brought together technical expertise in film emulsions and coating with acquisition of one of the former Leverkusen wide coating machines for film production, and a smaller narrow coating machine for testing, relocated to new premises in Monnheim on Rhein, the new smaller scale facility capable of multi-layer film coating for both ...
Various thin film characterization techniques can be used to measure the physical properties of PVD coatings, such as: Calo tester: coating thickness test; Nanoindentation: hardness test for thin-film coatings; Pin-on-disc tester: wear and friction coefficient test; Scratch tester: coating adhesion test
A film coating is a thin polymer-based coat that is typically sprayed onto solid pharmaceutical dosage forms, such as tablets, capsules, pellets or granules.Film coating can impact both its appearance and its pharmacokinetics making it an essential process in making the final drug product.
Limiting coating area is crucial in some applications, such as printing. "Roll-to-roll" or "web-based" coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. This continuous process is highly efficient for producing large volumes of coated materials ...
Each bar will give a "theoretical wet film thickness" or, in other words, the thickness of the coating that should remain on the drawdown card after application. Even with high manufacturing tolerances, the actual wet film thickness can vary from 50% to 90% of the gap. There are multiple types of bar applicators, their forms and uses are shown ...
A machine used for spin coating is called a spin coater, or simply spinner. [1] Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent is usually volatile, and simultaneously evaporates. The higher the angular speed of spinning
