Paint testing drawdown bar

The paint testing wire bar is made of stainless steel with specific depth grooves on its surface, which evenly transfers a quantitative amount of coating onto the substrate during application, forming a wet film of standard thickness. It is used in laboratories to simulate the actual coating process and evaluate the leveling, hiding power, and color uniformity of coatings. It is widely applied in quality control of coatings and the development and testing of new formulations.
Selection
When selecting, consider the groove depth of the wire bar corresponding to the required wet film thickness, with common specifications ranging from 25 to 200 micrometers. Choose different wire diameters based on the viscosity of the coating; use thicker wire bars for high viscosity. Stainless steel material ensures wear resistance, and immediate cleaning is required after use. Pay attention to the flatness of the substrate and the consistency of the coating speed.
