Vacuum Adsorption Heating Blade Coater

The vacuum adsorption heating blade Coater secures the substrate through vacuum negative pressure, reduces the viscosity of the coating with its heating system, and controls the coating thickness using a blade. It is used for uniform coating of materials such as paper and films, achieving quantitative coating and rapid drying.
Selection
When selecting, consider matching the substrate width to the coating width, ensuring the coating thickness range aligns with the doctor blade adjustment capability, the heating temperature covers the curing requirements of the coating, the vacuum adsorption force adapts to the material's breathability, and the equipment material is corrosion-resistant and compatible with the solvent type.
