Doctor Blade Coating Rod Small Coater

The small-scale applicator with a coating rod spreads the coating evenly onto the substrate surface through an adjustable gap, used for preparing thin film samples in the laboratory. It is suitable for quality control and new formulation development in the ink and coating industries, capable of forming a controllable thickness coating on materials such as paper and plastic.
Selection
When selecting, consider the substrate type and coating thickness range, match the specifications of the coating rod with machine compatibility. Focus on ease of operation and cleaning maintenance requirements, and determine the machine's adjustment precision based on the viscosity of commonly used coatings. Laboratory space and budget constraints are also practical considerations.
