Laboratory Plate Spreader

The laboratory coating applicator evenly spreads liquid samples onto the substrate surface using a blade or roller, forming a wet film of specific thickness. It is used for opacity testing and film-forming evaluation of coatings and inks, and is routinely employed in the preparation of coatings on paper and plastic substrates.
Selection
When selecting, consider matching the substrate dimensions to the coating width, ensuring the coating thickness range covers testing requirements, and observe the precision of coating speed adjustment. Pneumatic pressure types are suitable for high-viscosity materials, while manual types offer simple operation. Prioritize models made of corrosion-resistant stainless steel, and those equipped with leveling devices to ensure uniform coating.
