Abstract: The invention is generally directed to techniques for reducing premature drying of solvent-based coatings, including premature drying at sites on the apparatus that applies the coatings. By introduction of solvent vapor proximate to the coating apparatus, and by passively bringing the solvent vapor to the site, the risk of premature drying is reduced. In the presence of the solvent vapor, solvent in the coating fluid tends not to evaporate quickly. The solvent vapor may be introduced by any of a variety of solvent vapor emission devices, and may be brought to the site passively by, for example, increasing the concentration of solvent vapor in a boundary layer that moves with the substrate being coated, diffusion, or natural convection.
