A novel polymerizable surfactant was developed and utilized to prepare latex polymers and resins through emulsion polymerizations. These polymers were then evaluated in PSA and architectural waterborne coating formulations. The results showed that the new surfactant almost fully reacted during the emulsion polymerization, and reduced or even eliminated the free surfactant migration during film formation.
This article, the third in a series, covers work done to improve the water resistance of water-based emulsions by replacing conventional emulsion surfactants with surfactants that will react into the polymer matrix.

Bio-surfactants are a promising alternative to chemical surfactants in the development of eco-friendly and high-performance coatings due to their bio-degradability, low toxicity, renewable feedstocks, and enhanced performance in various aspects of coatings formulations.
There are key characteristics that differentiate legacy, petrochemical surfactants from bio-based surfactants, as well as chemically manufactured bio-surfactants from their biologically created counterparts, bio-surfactants.
For those looking to replace PFAS in their coatings formulations, this article discusses some experiments and data that show how organosilicones compare to PFAS compounds in critical performance criteria such as low surface tension/surface energy, COF, water repellency, oil repellency, stain resistance, and chemical stability.
This month’s Formulating with Mike columncontinues the focus on resins. Mike tests paints with APE-containing and APE-free emulsions for stability, particle size, and final paint quality.
This month’s Formulating with Mike columncontinues the focus on resins, and discusses acrylic emulsion polymerization, in particular, surfactant design and how it affects the polymerization of a vinyl-acrylic emulsion.
