Vacuum Adsorption Coating Tester

The vacuum adsorption coating tester generates negative pressure at the bottom of the substrate through a vacuum pump, ensuring the material is smoothly and uniformly adsorbed onto the coating platform. It is used in conjunction with a blade or roller to achieve even coating of liquids. This equipment is designed to simulate coating processes for materials such as paper and films, and to evaluate the uniformity of coatings and the effectiveness of adhesion.
