Paper Coating Layer Rod

A paper coating rod is a laboratory tool used to apply a uniform layer of liquid sample onto the surface of paper, forming a thin coating for testing thickness, uniformity, or drying performance. Its principle is based on the grooves on the rod body, which control the amount of coating applied. It functions by simulating industrial coating processes and is used for evaluating coating quality on materials such as paper and films.
Selection
When selecting a paper coating rod, consider the coating thickness range to match the sample viscosity; choose materials like stainless steel for corrosion resistance, and ensure the length accommodates the paper width; the groove accuracy affects coating uniformity, so specifications should be determined according to testing standards.
