The terminology, surfactant is a connected word, appropriately derived from surface-active agent. While used in an extensive range of industries, this blog post will focus on the use of surfactants in the CASE industry segment, where our products are applied in emulsion polymerizations and as stabilizers, dispersants, wetting agents and foam modifiers. The main functions of surfactants in water-based CASE applications are to emulsify water-insoluble, hydrophobic monomers to facilitate polymerizations in anemulsion state, and to stabilized suspensions of the resulting synthetic polymers so they can be stored, formulated and subjected to shear forces.
