BGD 226 Leveling Tester is designed to determine the relative leveling of liquid coating materials before curing in the laboratory. (Coating materials have to eliminate surface defect during drying).
It complies with ASTM D2801-1994 (BGD 226-1) and NYPC (BGD 226-2). It is made of stainless steel with straight scraper fitted with 5 pairs of notches of increasing depth from 100~1000μm (or 254~4064μm which equals 10-160 mils).

Technical Specification
Once the drawdown has been made on a horizontal, firm surface, leave the coating to cure. Once the coating is dry, identify the thickness at which the pair of film stripes merge.
