The Test Process Of Pigment For Water Based Ink Application

Color paste grinding: mixing with water-soluble resin, pigment, additives, solvent (water), etc., stirring and dispersing by a high-speed dispersant, and grinding into a color paste(concentration) for later use

Formulation: Mixed wth color paste,additives,solvent(water), then grinding and dispersing,Make it more fineness, good gloss and colorant, and Water based ink have to be filter package.

In summary, we choose various types water-soluble acrylic resin, Through the blending experiment of pigments and additives for selecting,

and compounding with acrylate emulsion, adding cross-linking agent, we get the optimization formula via these professional test.

we develop many pigment types for water based application by this formula,  and the good usage are praised by kinds of customers, who said our indicators have reached the advanced data of the same products around the domestic and abroad.
