Efka® PX 4703



EFKA® PX 4703 is an 100% acrylic block copolymer active dispersing agent based on our advanced polymer technology. It is especially recommended for high-performance systems such as inkjet inks (UV-curable and solvent-based) and UV-curable flexographic inks. EFKA PX 4703 is also well suited for high performance pigments in UV oligomer and monomer formulations, which makes it a general purpose dispersant. It can be applied in both solvent-based and solvent-free industrial coatings applications.
