Gap Coating Machine

The gap Coater controls the coating thickness by adjusting the gap between the blade and the substrate, utilizing blade coating to form a uniform coating. It is used in laboratories to prepare thin film samples and conduct precise coating tests on surfaces such as paper and plastic.
Selection
When selecting, consider the substrate width matching the size of the coating head, the coating thickness range covering experimental needs, the corrosion resistance of the blade material, the simplicity of equipment operation, as well as maintenance costs and availability of accessories.
