The performance of oil-based paints is generally better because the solvent acts as a plasticiser (197), and aids in the film formation process. The performance of the water-based paints can approach that of the solvent-based paints through careful formulation of the latex. Paints are usually formulated to contain 60 to 70 volume percent water.
