Abstract

The VOC and SVOC in interior wall coatings have negative impacts on bothindoor and ambient air quality,and it has become a trend to control them through product standard limits. However,there was no quantitative requirement for SVOC content limit ofinterior wall coatings in China and there was a gap in coordinating resaearch based on themeasured VOC and SVOC contents. In this paper,52 represetative samples from various purcahsing channels,brands,and product grades were randomly collected,and the VOC and SVOC contents of which were measured and analyzed. The resualts showed that VOC andSVOC were simultaneous detected in 69% of samples,and the VOC contents were lower than the SVOC contents. The highest frequency of VOC and SVOC contents distributed at 0~10 g/Land 40~50 g/L,respectively. The SVOC detction ratio and contens in“First Grade”products were both greater than that of“Qualified Grade”products,and which was most obvious for those products with high-boiling-point solvents. Thus the VOC and SVOC contents in interiorwall coatings should be coordinating limited. It is recommended to first clarify the definition ofSVOC and its content indicators in paint products in subsequent work,incorporate SVOC content limits into indoor air quality control indicators,and simultaneously conduct researchon active substances in coatings and their impact on environmental air quality.
