Batch Coater

The gap Coater controls the coating thickness by forming a fixed gap between the blade and the substrate. During operation, the substrate remains stationary while the blade moves to complete localized coating, making it suitable for small-batch sample preparation in laboratories. It is used for experiments on uniform coatings and quality testing of materials such as paper and films.
Selection
When selecting a gap Coater, considerations should include the substrate thickness and coating width, ensuring compatibility with the blade gap adjustment range. The blade material should be chosen based on the viscosity of the coating: steel blades are suitable for high viscosity, while plastic blades can be used for low viscosity. It is important that the equipment features a flat base and a pressure equalization system to ensure uniform coating.
