H-Sperse® is the registered trademark for Harcros Organics line of ionic and non-ionic dispersant materials. The line is comprised of various aliphatic alcohols and alkyl phenols, which have been alkoxylated for their particular applications. The non-ionic materials have been found to be particularly useful for the dispersion of carbon blacks. The ionic grades are phosphated or boronated versions of the non-ionic dispersants, and are useful for dispersing metal and metal oxide materials in difficult conditions. This is because the finished dispersions are essentially non-ionic, and insensitive to acid or alkaline pH conditions.
