Fish scraper

The drawdown bar is a tool used for testing in industries such as coatings and inks. It forms a uniform film layer on a test substrate through a drawdown method, allowing observation of its hiding power, leveling, and other properties. The principle is based on mechanical drawdown to produce a coating of standard thickness, which is used to compare color, hiding effect, and surface characteristics. Applications include laboratory quality control, formulation development, and rapid testing on production sites.
Selection
When selecting a scraper bar, consider the material's wear resistance; stainless steel offers a longer lifespan. Match it with the viscosity of the material being tested—choose a model with a larger gap for high-viscosity materials. Determine the scraping groove accuracy based on testing standards. The handle design affects operational stability. Ensure compatibility with existing substrate sizes to avoid edge overflow. Clean promptly after use to prevent residue from affecting subsequent results.
