Rod-Type Coating Machine

The rod Coater evenly spreads liquid coating on a substrate surface by rolling a metal rod, forming a thin film. It is used in laboratories to simulate the coating process, test the leveling and hiding power of coatings, and is suitable for coating preparation and quality control on paper and plastic films.
Selection
When selecting, consider matching the substrate thickness and width to the coating range, align the coating thickness requirements with the bar diameter, choose manual or electric operation based on experimental frequency, ensure material corrosion resistance is compatible with the coating type, and select additional functions like heating according to process requirements.
