Slot-die Extrusion Coater

The extrusion Coater uses a gear pump to extrude the coating from the storage tank, forming a uniform wet film through an adjustable slit. It is used in laboratories to prepare coating samples of standard thickness and, in combination with a wire-wound rod, to test the leveling, hiding power, and other properties of coatings.
Selection
When selecting, consider the coating width matching the sample size, the slit adjustment range covering the required film thickness, and the material's corrosion resistance to suit the type of coating. Check the pressure control precision to ensure uniform film formation, while also considering ease of cleaning and the equipment's footprint.
