Vacuum Heating Coating Tester

The vacuum heating coating tester removes bubbles by evacuating air, reduces coating viscosity through heating, and forms a uniform coating on the substrate. It is used to simulate coating processes, test coating properties such as adhesion and thickness, and is suitable for laboratory testing of materials such as paper and films.
Selection
When selecting, consider matching the vacuum range to the material's porosity, ensure the heating temperature covers the curing point of the coating, allow adjustable coating speed to accommodate different viscosities, ensure substrate clamp sizes are compatible with samples, use equipment materials resistant to solvent corrosion, and ensure an intuitive operation interface for easy parameter setting.
