BIUGED INSTRUMENTS offers a wide range of drawdown cards and charts for virtually any application and coating material. Stringent equality control during the production process assures that they have the most consistent color and gloss in the industry. Test charts are easy to use and an economical substrate to test a variety of coating properties, such as opacity, spreading rate, and flow& leveling behavior. They are used for testing architectural, industrial, automotive, wood finishes or even cosmetic products(e.g. nail polish) .Depending on the material properties of the product to be tested and its usage different types of drawdown cards are available.
Large size drawdown charts, referred to as display or spreading rate charts, were designed for visual evaluation of hiding powder. The diagonal striped patterns or the checkerboard respectively have a strong visual impact and emphasize variations in film opacity.
In order to calculate the spreading rate ASTM D 344 uses Forms 8H and 10H. In this test the paint is spread uniformly on a defined test area(0.1 square meters~1 square foot) and the spreading rate is calculated from the weight and density of the applied coating.
