Manual Coating Scraper Bar

The manual drawdown bar is a coating tool that forms a uniform wet film by evenly scraping a metal bar across a substrate. It controls coating thickness through grooves on the rod, making it suitable for testing the hiding power of inks and coatings and evaluating printability. In laboratories, it is commonly used for rapid prototyping and comparing the flow properties of different formulations.
Selection
When selecting, note that the rod material must be corrosion-resistant, with stainless steel being suitable for most solvent-based inks. The groove depth determines the coating thickness, so choose the corresponding specification according to the test standards. The rod length should cover the width of the substrate, and the edges must be smooth and free of burrs. During operation, maintain constant pressure and speed to ensure coating consistency.

Instruments

A wet film with a film thickness of 50~ 675 μ m was prepared by using a coating scraper, and the sag property was observed when placed vertically. The maximum thickness without sag was expressed, which was suitable for Paints testing.
