![]() ![]() ![]() Holding these applicators at a lower angle will reduce coating thickness down to about half of the maximum value. Each unit accommodates up to 40 samples to match. (2) A = appropriately sized metering rod B = appropriately sized ACCU DYNE Applicator TM, held at a 45° angle, which applies the maximum possible yield for each coating gate. Save time and space by using one or more Draw Down Drying Towers in your commercial or retail paint store. (1) Wet film thicknesses are approximate, and will vary slightly depending on coating viscosity, percent solids, and substrate absorptiveness. 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. Paint application onto a drawdown chart requires a highly precise coating applicator to achieve a consistent dry paint film. 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. ![]() Black and white cards are used to measure both opacity and contrast rat. The tools described in this section open up a variety of test options. Drawdown cards are used for testing paints and coatings through wet film preparation. Order now for only 3. Our 8' x 8' peel & stick color samples are available in our most popular colors. For best results, tests should be performed on a Diversified Drawdown Platform™ or a similar flat surface. Eliminate the guesswork with Twist-n-Pour Color to Go ® paint samples. 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. ![]()
