Aurora’s coating insolubilizer products are slightly cationic and form strong cross-linking bonds with anionic ions of latex particles and pigments, so it improves wet pick, wet rub and wet receptivity.
Coating insolubilizers gives these properties such as improving printability, wet pick, wet rub, opacity, improves blistering and reduces binder migration and mottling.
Water resistance is an important factor in pigment coated paper for offset color printing. These papers need high water resistance in a moisture environment.
