A one-dimensional VOC emission model of moisture-dominated cure adhesives

Abstract Moisture-dominated cure adhesives (e.g., silicone sealant) are an important source of volatile organic compound (VOC) emissions indoors, particularly in newly decorated buildings. Understanding their emission behavior could aid in selecting better control strategies for acceptable indoor air quality. In this study, a one-dimensional emission model that can predict the entire VOC emission process from moisture-dominated cure adhesives was established. The model has distinct physical or chemical parameters; thus, the model can be readily scaled up and the effects of environmental factors, such as temperature and humidity, can be evaluated. The emission of a type of neutral silicone sealant was measured using an environmental chamber and the main emission VOC (2-butanone oxime, MEKO) was used to validate the model. The model parameters of neutral silicone were measured or estimated to predict the concentration in the chamber. The experimental data and model predictions agreed well. The study indicates that MEKO emission is strongly coupled with the curing process. The factors that can influence the cure reaction are also the main influencing factors on the MEKO emission process.
