Fumed Silica in Printing Inks application
Fumed silica plays a broad role in the field of printing inks. Given that printing is a high-speed process, the rheological properties of the ink must be capable of withstanding various physical forces to achieve impeccable printing results. The ink should not splatter, needs to dry quickly, and must leave clear images on paper, polymer materials, or metal surfaces.
Fumed Silica can impart superior properties to printing inks
It enhances the brightness and color density;
It reduces color intensity, minimizing peeling by using less viscosity modifier;
During storage, it improves the stability of pigment and filler dispersion;
In the printing process, it controls rheological properties, leading to sharper printing and contours, preventing or reducing streaks;
It controls the ink’s moisture content, reducing settling and promoting better stacking;
It prevents sticking, avoids flying or blurring, reduces strike-through, and controls gloss levels;
It increases the water resistance of water-based flexo inks, reducing unnecessary sliding during the printing process.
