Laboratory spreading Rod

The laboratory coating rod features grooves of specific depths carved on the surface of a metal rod, which is used to spread coating samples on glass or metal substrates to form a uniform wet film. It is employed in the paint and ink industry for preparing test film layers, and works in conjunction with drying ovens or thickness gauges to verify the uniformity of film thickness.
Selection
Select the groove shape based on the viscosity of the sample to be tested: use a circular groove for high viscosity and a wedge-shaped groove for low viscosity. Match the groove depth specification to the expected film thickness, commonly ranging from 25 to 500 μm. Consider the substrate flatness; for curved substrates, choose a coating rod made of flexible material. After use, clean the groove with solvent to prevent residue buildup.
