DELTA DC® 3401

Modified polyurethane. Prevents reflocculation of pigments through steric hindrance and therefore stabilizes the color strength and hue of pigments in paints and pigment concentrates. Shows a wide compatibility, from low- to high-polarity systems, including nitrocellulose. Has been developed for high performance solvent-based coatings. Does not influence paint binder durability due to its high molecular weight and resin-like structure. Enhances processing of pigment bases during grinding and enables higher pigment loads to be achieved. Improves color strength and reduces dispersion time. Possesses lower viscosity and higher gloss. Has broad solubility behavior and suited to a wide variety of resin systems. Should not be used with chlorinated polymers or epoxides due to tendency of these combinations to yellowing and/or gellation. Used in liquid inks, pigmented bases, UV-curable inks, screen printing inks and gravure printing inks. Also used in industrial coatings, automotive coatings and pigment concentrates.
