This article, the conclusion of a five-part series, covers work done on using reactive surfactants to make styrene acrylic emulsions with better water resistance.

This article, the fourth 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.

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 month’s Formulating with Mike column continues the discussion on resins, with a focus on epoxy curing agents. When it comes to great adhesion, chemical resistance, and corrosion resistance, an epoxy is hard to beat. There are different epoxy curing agents, and each one provides different properties that can be suited for a wide variety of end-use applications. 

This month’s Formulating with Mike column continues 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 Did You Know column discusses several classes of hybrid latex particles.

This month’s Formulating with Mike column continues the focus on resins, and discusses acrylic emulsion polymerization, in particular, surfactant design and how it affects the polymerization of a vinyl-acrylic emulsion.
