Column Coater

The rod Coater transfers the coating material by rolling a cylindrical rod with surface graduations, creating a uniform wet film on the substrate. It is used in laboratories to prepare standard coating samples for testing properties such as hiding power and leveling of coatings.
Selection
When selecting, consider the compatibility of the substrate material and size with the width of the Coater, choose an appropriate groove depth based on the required coating thickness, verify the accuracy of the cylinder scale and the wear resistance of the material, and determine the model based on the viscosity range of commonly used coatings.
