AERODISP® WK 7330

AERODISP® WK 7330 by Evonik is a cationic, aqueous dispersion of fumed silica and a fumed mixed oxide with high solids content and a positive zetapotential. It is used as a sizing or coating pigment for inkjet paper to enhance color strength (gamut and optical density), print uniformity (mottle and grain), print resolution (line growth, raggedness, and blur), water fastness, and coefficient of friction.

• It is also suitable for modifying electrophoretically deposited metal layers.
• It enables excellent dot sharpness and resolution, crucial for high-quality digital printing.
• In order to achieve high-quality results, it is necessary to control the spreading behavior and fixation of the inks on the substrate.
• It provides positively charged solid particles, nano-sized primary particles, superior rheological behavior and high formulation flexibility and ease of handling.
• AERODISP® WK 7330 is compatible with non-ionic and cationic binder systems, making them the first choice for primers such as textile inks.
