Characterization of Organic Emissions from a Wood Finishing Product – Wood Stain

The paper gives results of the measurement of emission characteristics of four organic compounds (nonane, decane, undecane, and 1,2,4-trimethylbenzene) from a wood finishing product, wood stain, in an environmental chamber. It was found that the emission patterns of the four organic compounds can be described by a two-phase model: phase 1, when the wood stain is relatively wet; and phase 2, when the wood stain becomes relatively dry. The changes of emission mechanisms between phases 1 and 2 were reflected by the significantly different emission and decay rates measured during the two periods. A relationship was found that can be used to predict the relative emission and decay rates of the four organic compounds from the wood stain.
