ECO Zephrym™ PD 2206

ECO Zephrym PD 2206 is a nonionic block copolymer dispersant which enables dispersion of both organic and inorganic pigments and fillers, including carbon black. Being zero VOC as well as excellent ability to disperse and stabilize particles in low polarity solvent and resin systems, ECO Zephrym PD 2206 is well suited for use in liquid colorant systems for plastics as well as in coatings applications. ECO Zephrym PD 2206 is available as part of Croda’s 100% renewable, 100% bio-based ECO Range of surfactants.
