The Role of ABA Surfactants in Waterborne Formulations

A major challenge within the coating and ink industries is to formulate more environmentally acceptable end products that comply with increasingly restrictive governmental regulations on volatile organic compounds.  However, the technological switch from a dependence on hydrocarbon systems will not be an easy one since there are inherent problems associated with potential waterborne alternatives.  Application, performance, and formulating challenges include wetting over low energy surfaces, foam, water sensitivity, rheology, and flow and leveling.

This paper will review the chemistry, theory, and application of surfactants in a wide array of waterborne applications.  Topics covered will compare the structures and behavior of both nonionic and ionic surfactants.  An understanding of how surfactants function with respect to surface tension reduction, foam stabilization and control, micro-foam, wetting of low energy substrates, pigment dispersion and stabilization, water sensitivity, VOC implications, and effects on rheological behavior will be covered.
