Investigation of odor emissions from coating products: Key factors and key odorants

Coating products are widely used for the interior decoration of residential property. However, there is growing concern regarding their odor emissions and impact on indoor air quality (IAQ). Most manufacturers government agencies set intensity limits to control coating products, including raw materials. it difficult determine product performance by means index. Although evaluating requires assessors distinguish between different levels, low consensus reproducibility represent challenges that avoid. As concentration index only ascertain whether felt or not, evaluation results relatively better. Moreover, suitable methodologies determining concentrations in volatile have rarely been reported. Therefore, establishing an method exploring its key influencing factors should bridge this gap. We examined influence airbag material recovery rate typical organic compounds (VOCs) using direct injection GC-MS established adsorption effects were order: PET > PVF PTFE. then explored influences sample curing emission times concentration. The solvent-based water-based coatings reached equilibrium after 8 h 16 curing, respectively, 12 emission, respectively. real samples measured compared against intensities. more accurately reliably discriminated than approach. Thus, assist improving formulations reduce we headspace gas chromatography substances water- analyzed contribution various activity value (OAV) method. Butyl acetate, ethylbenzene, 1-methoxy-2-propyl acetate odorants while 1-butanol, butyl coatings.
