Set Contains: Drawdown Bar Film Applicator^Theoretical Wet Film Thickness (20.0 mils)^Gap Clearance (40. The actual wet film thickness can vary from 50% to 90% of the gap depending on the gap clearance. The drawdown process consists of many variables. Several options for bar diameter and lengths available. Bar sizes of 0 to 90 available (0 to 228 micron wet film thickness). A steel clip holds the test chart or panel steady while the drawdown is made. The drawdown surface is sturdy polished glass, equal in planarity to fine mirror glass. One edge produces a 3mil thickness of ink and the other edge. Leneta drawdown plates consist of a precision flat solid glass panel mounted on rubber bumpers to prevent sliding while in use. We cannot guarantee that you will draw-down the theoretical wet film thickness. Available as a wire wrapped bar or a machined bar. These Draw Down Bars are used for putting plastisol and water-based ink onto an opacity card. If you have a gap clearance of 6 mils, the theoretical wet film thickness etched on the bar applicator is 3 mils. The theoretical wet film thickness is etched onto every drawdown bar and is roughly one-half the actual gap clearance.
