Paint Wire Scraper Rod

The paint wire-wound drawdown bar is constructed from a metal rod wrapped with wire, which controls the thickness of the paint application through the gaps between the wires. It is used in laboratories for manually preparing uniform paint films and, in conjunction with a wet film thickness gauge, for conducting basic tests such as coating hiding power and leveling properties.
Selection
Select the wire diameter and winding spacing based on the viscosity of the coating to be tested. High-viscosity coatings require specifications with thicker wires and wider spacing. Choose an appropriate rod length considering the flatness of the substrate, and opt for stainless steel material to resist solvent corrosion. After use, promptly clean the gaps between the wires with the corresponding solvent.
