Four-corner preparator

The four-sided applicator forms a uniform wet film on the substrate surface through a coating method, used for preparing film thicknesses of coatings, inks, and other samples. The principle involves adjusting the gap between the blade and the substrate to control thickness, and its purpose is to provide standard samples for subsequent performance testing. It is applied in laboratory quality control and product development.
Selection
When selecting a four-sided applicator, it is essential to consider the compatibility of the substrate size with the applicator specifications, determine the thickness range based on testing standards, inspect the flatness and gap accuracy of the blade, ensure the material's corrosion resistance aligns with sample characteristics, and verify that the operational convenience meets usage requirements.
