![]() ![]() To determine dry film weight, multiply table values by percent solids. WFT,Ĭoating weights are based on a coating density of 1 g/cm 3 (8.345 lb/gal). Please email or call us for advice on your specific application. A Universal Blade Applicator can produce any wet film thickness from 0 to 5 mils or 0 to 25 mils, depending on the design chosen and how it is adjusted. Additionally, many alternative coating thicknesses can be produced with special order metering rods. The following table shows the wet film thicknesses, coverage, and wet film weights that can be produced with our stock metering rods and ACCU COAT Applicators™. Even when the drawdown method does not directly emulate a planned production process, it may be a useful pre-production test to screen materials or drying and curing methods. The tools described in this section open up a variety of test options. For best results, tests should be performed on a Diversified Drawdown Platform™ or a similar flat surface. ![]() Drawdowns allow easy evaluation of wettability, opacity, color match, gloss, tack strength, drying weight, dye uniformity, degree of pigment dispersion, and other attributes. Since most coating properties are thickness-dependent, it is imperative that the optimum thickness be determined for each application. The drawdown test is a fundamental laboratory technique which is used to evaluate interactions between flat surfaces (such as film, foil, and paper) and a myriad of inks, coatings, paints, suspensions, adhesives, colloids, powders, etc. ![]() Note: drawdown is shown at accelerated speed. ![]()
