Laboratory Paper Coating Rod

A laboratory paper coating rod is a tool with specific depth grooves engraved on the surface of a metal rod. Its principle involves using the grooves to carry a precise amount of coating material, which is then evenly spread over the paper surface at a constant speed to form a uniform wet film. Its function is to simulate the industrial coating process in a laboratory setting, used for coating tests and quality control on substrates such as paper and films.
Selection
The selection of a coating rod should match the substrate thickness and coating characteristics. For thinner substrates, choose a rod with a smaller gap; for high-viscosity coatings, opt for a rod with wider grooves. Consider whether the coating width aligns with the sample size. Stainless steel material offers corrosion resistance, while carbon steel is suitable for routine use. Verify whether the coating thickness meets the testing requirements, and ensure the rod’s straightness and flatness.
