High performance polymeric dispersant for carbon black in water-borne systems

 
Carbon black is one of the most useful yet challenging pigments in the coatings industry. In order to obtain maximum jetness and shelf stability with this pigment, it is essential generate highly effective dispersions. The resulting millbase must also be compatible with multiple resins to ensure consistent color development in a wide range of coatings. In addition, the dispersant package is required to have minimal impact on final film properties and on the environment. In this talk, a new dispersant platform will be described which relies on sophisticated molecular architectures and functionalities to effectively wet and stabilize multiple carbon black grades without the help of auxiliary additives. Experimental results will be presented that demonstrate the technology's superior performance in automotive coatings and its ability to meet every requirement described above.
