Knife Coater

The film applicator forms a thin film by evenly spreading liquid material on the substrate surface using a blade. It is used in laboratories to simulate industrial coating processes and to test the leveling, hiding power, and film thickness consistency of coatings and inks.
Selection
When selecting, consider matching the substrate size to the coating width, ensuring the coating thickness range covers testing requirements, the scraper material's corrosion resistance suits the sample characteristics, the operation method meets precision requirements, and configure additional functions such as temperature control based on actual needs.
