Stainless Steel Coating Spreader Bar

The stainless steel drawdown bar creates a uniform gap through its precisely machined cylindrical metal body, allowing it to scrape a wet film of fixed thickness onto the substrate surface. It is used for coating and ink sample preparation, and can be used in conjunction with drying ovens or thickness gauges for coating performance testing.
Selection
Select the rod diameter based on the viscosity of the material to be tested, determine the wire diameter according to the testing standards to control the coating thickness, match the rod length to the substrate width, and prioritize the use of 316 stainless steel material to handle corrosive samples.
