BYK-Gardner Drawdown Cards & Panels
BYK-Gardner Drawdown Cards & Panels are test substrates used to create consistent film applications of paints, coatings, inks, varnishes, adhesives, and other liquid materials through the drawdown process. These products help users evaluate opacity, hiding power, spreading rate, penetration behavior, flow, leveling, color, gloss, and final coating appearance in a practical, repeatable, and easy-to-document way.
In coating testing, selecting the right drawdown card or panel is important because the substrate can affect both visual and instrumental evaluation results. Black and white areas on opacity cards help assess coating hiding power, while penopac cards are used to observe appearance changes between sealed and unsealed areas. Display or spreading rate cards provide a larger area for visual hiding power evaluation, while plain white or plain black cards are suitable for color testing, special effect coatings, and cosmetic coatings.
BYK-Gardner Drawdown Cards & Panels are available in various options such as opacity drawdown charts, penetration and opacity cards, display-spreading rate cards, brushout cards, plain white cards, plain black cards, uncoated cards, gray scale charts, spray monitors, clear polyester film, and veneer panels. These products are suitable for architectural coatings, industrial coatings, automotive coatings, wood finishes, printing inks, cosmetics, nail polish, water-based systems, solvent-based systems, R&D, color matching, quality control, formulation comparison, and batch consistency evaluation.
