[Emission of volatile and semivolatile organic compounds from water-based akrylate paints]

Identification and testing of organic compounds emissions from water-based akrylate paints were conducted. TD-GC/MS system was applied for identification of compounds. Emission was monitored in an environmental chamber with controlled temperature, relative humidity, and air exchange. Quantitative analysis was measured by GC method. Emission of main volatile organic compounds (VOC) semivolatile organic compounds (SVOC) and total volatile organic compounds (TVOC) were defined in various periods of time, within 30 days after paints application. The main organic compounds indicated high level of an initial emission after 24 hours. Some of water-based akrylate paints may release small quantities of SVOC (texanol) even 30 days after their application. It was demonstrated that the first-order emission decay model well describes the emission course from water-based paints.
