AbstractThis research is to develop a mass-transfer model for describing the emission of volatile organic compounds (VOCs) from architectural coatings, which accounts for both surface evaporation and internal diffusion during the drying period. To apply this model, it is necessary to know the evaporation and diffusion coefficients of VOC emitted from the coating materials. An experimental method was, therefore, developed to determine both the evaporation and diffusion coefficients for six aliphatic hydrocarbons and six aromatic hydrocarbons from oil-based paint. It was shown that diffusion coefficients are inversely proportional to molecular weight, while evaporation coefficients are proportional to vapour pressure of the VOCs.
