Boiling point and distillation range

Flash point is one important indicator of the relative flammability hazard of solvents and solvent-containing products therefore. 

Flash point is roughly inversely proportional to volatility. When there are mixtures of miscible solvents, which is true for most coatings, in most cases the flash point can be assumed to be that of the solvent with the lowest flash point, provided that a substantial proportion of that component is present, such as 5 % or more.
