Evaporation rates of solvents

WebMar 16, 2009 · Evaporation Rate: In order to understand the precautions necessary for handling a particular solvent, you must examine the rate of evaporation. Once a particular solvent-containing material (ex. paint mixed with solvent, or marker) is applied to a surface and dries, the solvents in that material evaporates.
