Salthammer, T; Bednarek, M; Fuhrmann, F; Funaki, R; Tanabe, S -I Formation of organic indoor air pollutants by UV-curing chemistry Journal Article In: Journal of Photochemistry and Photobiology A: Chemistry, vol. 152, no. 1, pp. 1 - 9, 2002, ISSN: 1010-6030. Abstract | Links | BibTeX | Tags: Acrylates, Degradation product, emission testing, Photoinitiator, Surface coatings, UV-curing @article{SALTHAMMER20021,UV-curable systems for manufacturing of furniture and parquet form a major and growing field in radiation curing. Numerous types and combinations of photoinitiators have been developed for crosslinking of acrylated systems and unsaturated polyesters. The properties of the photoinitiators being used in these materials must fulfill requirements like low toxicity, low odor and high reactivity. However, volatile reaction products being produced during the photochemical process contribute to the pollution of indoor air by emission from the surface and may cause strong odor and adverse health effects. Therefore, the release of photoinitiators, fragmentation products and monomers from UV-cured coatings was studied as a function of time under realistic living conditions in emission test chambers and cells. Main components detected in the chamber air were benzaldehyde, cyclohexanone, benzophenone and acrylate monomers. The area-specific emission rates SERA were found to be strongly dependent on the climatic conditions. |

Wolkoff, Peder Impact of air velocity, temperature, humidity, and air on long-term voc emissions from building products Journal Article In: Atmospheric Environment, vol. 32, no. 14, pp. 2659 - 2668, 1998, ISSN: 1352-2310. Abstract | Links | BibTeX | Tags: Air velocity, building products, emission testing, FLEC, relative humidity, repeatability, temperature, VOCs (volatile organic compounds) @article{WOLKOFF19982659,The emissions of two volatile organic compounds (VOCs) of concern from five building products (BPs) were measured in the field and laboratory emission cell (FLEC) up to 250d. The BPs (VOCs selected on the basis of abundance and low human odor thresholds) were: nylon carpet with latex backing (2-ethylhexanol, 4-phenylcyclohexene), PVC flooring (2-ethylhexanol, phenol), floor varnish on pretreated beechwood parquet (butyl acetate, N-methylpyrrolidone), sealant (hexane, dimethyloctanols), and waterborne wall paint on gypsum board (1,2-propandiol, Texanol). Ten different climate conditions were tested: four different air velocities from ca. 1cms-1 to ca. 9cms-1, three different temperatures (23, 35, and 60°C), two different relative humidities (0% and 50% RH), and pure nitrogen instead of clean air supply. Additionally, two sample specimen and two different batches were compared for repeatability and homogeneity. The VOCs were sampled on Tenax TA and determined by thermal desorption and gas chromatography (FID). Quantification was carried out by individual calibration of each VOC of concern. Concentration/time profiles of the selected VOCs (i.e. their concentration decay curves over time) in a standard room were used for comparison. Primary source emissions were not affected by the air velocity after a few days to any great extent. Both the temperature and relative humidity affected the emission rates, but depended strongly on the type of BP and type of VOC. Secondary (oxidative) source emissions were only observed for the PVC and for dimethyloctanols from the sealant. The time to reach a given concentration (emission rate) appears to be a good approach for future interlaboratory comparisons of BP’s VOC emissions. |
