Wire Bar Coating Tester

The wire rod Coater forms a wet film of specific thickness on the substrate surface by rolling a metal rod wound with steel wires. It is used to simulate the blade coating process and evaluate properties such as the leveling and hiding power of coatings. It is suitable for quality control in industries such as inks and paper.
Selection
Select the wire diameter specification based on the viscosity of the sample to be tested, and match the rod material with the substrate type, ensuring coverage of common coating thickness ranges. The operation methods include manual and electric, with benchtop or portable options chosen according to laboratory space. Pay attention to the machining precision and wear condition of the rod.
