The hydrophobe used to make this material will attach to a wide variety of different particles making it valuble as a general purpose dispersant. Dispersions made using H-Sperse® 5000N demonstrate long term viscosity stability. As a non-ionic dispersant, it makes dispersions that will be stable under a wide range of pH conditions, both acidic and basic. Viscosity may vary with pH, so this must be explored to determine the best pH for the application. It is especially suitable for making dispersions of carbon black. view less | |

The ionic phosphate groups bind tightly to a variety of inorganic materials, while the non-ionic hydrophobe portion will prevent agglomeration and flocculation of many types of inorganic particulate materials. It is APE/NPE free, and exhibits very low toxicity. The phosphate functional group promotes excellent adhesion to the inorganic particulate giving good dispersion stability under difficult conditions, such as highly saline solutions. The phosphate groups can also enhance fire retardancy. In addition, the phosphate groups can also enhance corrosion resistance in coatings applied to metals. view less |
