A model is developed for predicting long-wavelength film thickness nonuniformities in drying latex paint films. After applying the lubrication approximation to the model equations, both linear and nonlinear stability analyses are performed. For the linear stability analysis, spatially independent base state solutions are found. These equations are solved numerically and a linear stability analysis of these base state solutions is conducted. In this case, the base state solution of the height represents a uniformly drying latex paint film with respect to time. For the nonlinear stability analysis, the leading order equations are solved numerically. The stability of the film is dependent on temperature, latex particle volume fraction, titanium dioxide particle volume fraction, extender particle volume fraction, surface surfactant density, bulk surfactant density, and several material and environmental factors. Slow evaporation, temperature gradients, surfactant desorption, surface tension gradients, low initial surface tension are identified as destabilizing mechanisms while fast evaporation, fast surfactant adsorption, high initial surface tension, high particle volume fractions, and viscosity are identified as stabilizing mechanisms.
