Gap Coating Machine

The gap Coater controls the coating thickness by adjusting the gap between the blade and the substrate, forming a uniform coating layer. It is used in laboratories to simulate coating processes and test the spreadability and coverage of coatings on materials such as paper and films.
Selection
When selecting, consider the compatibility of the substrate type and width with the machine specifications. The coating thickness range should cover the experimental requirements. Pay attention to the corrosion resistance of the blade material. The equipment must have precise gap adjustment capabilities, and the operation interface should be simple and clear.
