This company has developed a new production method - heterogeneous (emulsion) polymerization - for its high-molecular-weight polymeric dispersants. EFKA-4580, the first product manufactured using this new process, is a polymeric dispersant for the deflocculation of pigments in aqueous coatings and pigment concentrates. This material is insoluble in water, and offers the following advantages compared to existing technologies: improved water resistance; better viscosity reduction; and improved viscosity stability during storage of pigment concentrates.
