Many important performance attributes of a coating film can be impacted by the dispersion quality of pigments and their interactions with polymeric binders. Improved pigment dispersion quality has been found to minimize photo degradation on latex paint films, which not only extends paint service life, but also can contribute to optimizing paint formulation costs. Adsorbing latex technology facilitates the controlled formation of self-assembled polymer-pigment composites, which in turn, creates more ordered paint films. These smarter materials, with improved pigment efficiencies, are a step-change improvement of dispersion quality over conventional paint binders. The impact on eco-footprint has been validated by 3rd party validated life cycle assessment. Poster topics will include: 1) Key factors facilitating the formation of stable polymer-pigment composites, 2) their impact on performance, as studied through analytical science, polymer chemistry, applications testing and 3) the mechanism and measurement of coatings degradation. Considered both a commercial and technical success, this technology continues to enjoy broad market adoption and has been awarded the prestigious Presidential Green Chemistry Challenge Award by the United States Environmental Protection Agency.
