Abstract

Solvent-based interior coating materials have long been recognized as a major source of volatile organic compounds (VOCs) in the indoor environment. In the emission process, substrate acts as a secondary source. The sink effects are studied with a detailed mass transfer model considering convective mass transfer in air streams, the VOCs diffusions in painting film, and the sorption and diffusions of VOCs in substrate. The model is proposed and validated by the emission profiles of a water-based emulsion paint in a standard field and laboratory emission cell. The focus is on the role the substrate plays in the emission process. The effects of the substrate parameters, such as the substrate diffusivity and sorption characteristics, on the emission profiles are investigated. This is helpful in exposure control through both selecting healthy materials and proper ventilations.
