“…This study aims to clarify the characteristics of chemical substances emitted by W1 class low-VOC paints and sealers by conducting emission rate tests and investigate whether they contain chemical substances which may have adverse effects on human health. Sealers are always used in combination with paints to improve paint performance (Boxall et al 1992). Kobayashi et al (2010) have pointed out that sealers also emit Texanol ™ , which could be a cause of SBS.…”

Globally, sick building syndrome remains a considerable social issue. It is primarily caused by the emission of volatile organic compounds (VOCs) from construction materials. Among these, paints and sealers are used over wide swaths of are a and their use causes chemical substances to be released in a room. To prevent sick building syndrome, it is necessary to clarify the cause of air quality changes due to the different types of paints and sealers available. Recently, low-VOC paints (containing 0.3-1.0% VOCs) have been used widely; however, the effects of reducing VOC levels have not yet been fully quantified. This study aims to clarify the chemical compositions by conducting an emission rate test of these low-VOC paints and sealers. We prepared six specimens and used them for chamber testing. Three types of paint with and without a sealer were tested. The minimum and maximum total volatile organic compound (TVOC) concentration was 96 and 4750 μgm −2 h −1 , respectively. Differences in the VOC content of the paints and sealers could be confirmed. The main TVOC was Texanol ™ and glycerol ethers. The results demonstrate that using paints containing less than 0.3% VOCs can decrease the VOC emission rate considerably compared to paints classified as less than 1% VOCs. Moreover, because different kinds of sealers affected the results, it is possible to decrease VOC emission rate using a variety of sealers.

Wood coating research almost exclusively focuses on softwood as substrate despite the fact that coatings applied on tropical hardwoods show a different weathering behaviour. The objective of this study was to quantify the impact of wood substrate and coating type on the weathering behaviour of finished wooden joinery in outdoor exposure using a set of statistical methods. Therefore, a broad range of white opaque paints and mid-oak semitransparent stains were used. The coatings were industrially applied on window frames made of frequently used commercial tropical hardwood species. The general appearance of the wood/coating systems was assessed visually using a rating scale that takes into account the anatomical characteristics of hardwood. A minimum required exposure time for evaluation of 2.5 years outdoor weathering for joinery in vertical position and facing south-west was determined. At 30 months best performances were recorded for waterborne alkyd primers with an acrylic topcoat when dry coating film was sufficiently thick. The dry layer thickness also affected the impact of the hiding power on the performance of the wood/coating system. Within hardwood species the degradation rate of coatings on species with a fine texture was the lowest. The significant influence of the substrate's texture on the weathering behaviour of coated hardwood stressed the need to evaluate the wood/coating system in total.
