Blending multiple latexes to formulate waterborne architectural paints is often practiced targeting a better balance of properties compared to the formulations containing individual latexes. Unfortunately, mixing numerous combinations of individual latexes with structural incompatibility can decrease miscibility resulting in an unacceptable degradation of one or more desirable properties. The interaction of these latex blends with formulation parameters such as additive package, volume solids, and pigment volume concentrations also significantly impacts the paint performances. This study utilized design of experiments (DOE) and high throughput methodologies in its approach to investigate the impact of blending poly (vinyl acetate) latexes with acrylic latexes on multiple paint properties. I-optimal DOE was conducted for estimating Taylor-Series Expansion models involving main effect and up to three factor interaction terms. After data collection and analysis, predictive models were developed for each property to estimate the trends and associations with the variables. Predictive models were also utilized for optimizing multiple responses in order to achieve desired performance balances.
