“…were highly diluted, so the large excess of water dictated the partitioning of the coalescing aids. From data available in the article by Vignola et al . and with distribution coefficients provided by Taylor and Klots, we estimated that the concentrations of all hydrophilic and hydrophobic coalescing aids were lower than 0.01% in water.…”

“…The addition of coalescing aids is a convenient and flexible way of solving the so‐called film‐formation paradox and has been a subject of many research articles. The effects of coalescing aids have been studied by researchers in terms of partitioning in the wet stage and T g reduction, dispersion stability and viscosity, polymer interdiffusion, and film formation in general …”

Coalescing aids are organic solvents that are widely used to accommodate the film formation of waterborne coatings. The influence of the volatility, hydrophilicity, and amount of coalescing aids on the properties of waterborne dispersions and the dynamics of film formation was investigated. The results show that coalescing aids increased the viscosity through particle swelling and solvation, with the effect being stronger with more hydrophilic solvents. The results obtained with electrochemical impedance spectroscopy (EIS) and indentation tests show that hydrophilic coalescing aids were more efficient because of the partitioning on the particle interfaces but they could temporarily decrease the water resistance. The ease of coalescence was countered by solvent retention, which complicated the dynamics of film formation. EIS was used to optimize a real‐world coating formulation and identify the pitfalls arising from the complex dynamics of film formation. The best resistance to humidity was obtained with a combination of hydrophobic and hydrophilic coalescing aids. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45142.

“…Vignola et al [ 19 ] observed that the effect of coalescing agent on a surfactant-stabilized latex varies with the nature of the coalescing agent. Paint flocculation was caused by the effect of the coalescing agent on the partitioning of surfactants between the polymer interface and the water phase.…”

A fluorescence approach to investigate repartitioning of coalescing agents in acrylic polymer emulsions

et al. 2011

Repartitioning of co-solvents between particles of latex emulsions was investigated by means of a fluorescence method based on the detection of the amount of co-solvent via the solvatochromic shift of the emission maximum of a fluorescent probe, copolymerized at a low concentration. Complete repartitioning of co-solvents between particles of latex materials with a low Tg (ca. 25 °C) occurred within minutes. For a hydrophilic latex with a Tg of 68 °C, equilibration was achieved within an hour. Repartitioning was faster for more hydrophobic co-solvents. For a hydrophobic latex of similar Tg, co-solvent repartitioning took place on the same time scale, but complete equilibration was not reached. Possibly, there is an additional slow component in the repartitioning, or the prolonged presence of co-solvent causes a structural change in the latex particles that affects the outcome of the experiment.
