We offer 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 typesof drawdown cards are available.

Selection of test charts dependenton coating technology
     Depending on the types of solvent used in paint formulations a drawdown chart needs to be more or less solvent resistant. The resin type requires differentsolvent types and dependent on the polarity of the solvent, the organic ingredients will be more or less activated. Therefore, we offers two types of drawdown cardsand charts.

Clear-coated Charts:
◆ Are ideal for a wide rangeof coating systems: water and solvent borne technologies
◆ Guaranteed non-fluorescent paper in compliance with ASTM D 344
◆ Repeatable color and gloss-lot after lot
◆ Superior adhesion characteristics, especially with latex paints
◆ Rugged design (0.5 mm thickness)to prevent warping and bending after the coating is applied.
◆ Package is shrink-wrapped with low permeability plastic to prevent moisture absorption during shipping and storage.
◆ Lot number are printed onevery charts

Film Laminated Charts:
◆ With excellent solvent resistance
◆ Repeatable color and gloss-lot after lot
◆ Smooth, structure free surface
◆ Superior adhesion propertiesand flexibility
◆ With 0.5 mm thickness
◆ Double film laminated will not warp and bend-even in highhumidity environments.
