Automatic Liquid Film Coating Rod

The automatic liquid coating rod uniformly spreads a liquid sample into a wet film of a specified thickness by driving a metal rod to move at a constant speed over a substrate via a motor. It is used in laboratories to prepare standardized coating samples for subsequent drying or curing processes. It is suitable for quality control and research and development testing in industries such as coatings and inks.
Selection
Select the groove shape of the rod based on the sample viscosity: use a round groove for high viscosity and a sharp groove for low viscosity. Match the specification size of the rod scale according to the desired wet film thickness. Determine the coating width based on the substrate size, and choose a coating rod with an appropriate surface material that matches the sample characteristics.
