Electric Coating Tester

The electric coating tester uses a motor to drive the blade to move at a constant speed, evenly applying the coating onto the substrate surface, simulating coating effects of different thicknesses. It is suitable for quality control and process research in industries such as inks and paper.
Selection
When selecting, consider matching the substrate size to the coating width, ensuring the coating thickness range covers experimental requirements, the motor stability affects coating uniformity, and additional functions such as temperature control are determined based on material characteristics.
