We at DOXA recently conducted a study on neutral carbon black in polyol the relative effects two of our dispersing agent grades, D-578 and D-950.
Spredox D-578 is designed to disperse carbon black and organic pigments. It is fashioned to have a wide compatibility with organic solvent and resins and to achieve a well-dispersed and stable state of dispersion. It is a premium dispersing agent to satisfy the toughest coloring requirements.
Spredox D-950 is a synergist designed to be used in conjunction with other dispersants to grind carbon black, blue and green organic pigments. It can further enhance the dispersion and lead to better color development and flow property.
The results from our lab shows that you can achieve even better dispersing and viscosity reduction effect when these two products are used in conjunction.
