Small Vacuum Coating Testing Machine

The small vacuum coating tester removes bubbles through a vacuum environment, ensuring uniform application of the coating on the substrate surface. It is used in laboratories to simulate coating processes and test the film-forming effects of materials under vacuum conditions, making it suitable for coating development on substrates such as paper and films.
Selection
When selecting, consider the compatibility of the coating speed range with the substrate width, ensure the vacuum level meets the material's outgassing requirements, and confirm the heating system is suitable for the sample's drying conditions. Pay attention to the compatibility between the coating head type and the slurry characteristics, select equipment materials that are corrosion-resistant and easy to clean, and ensure the control interface is user-friendly and easy to operate.
