0VOC

0VOC is a marketing designation used for certain paints, coatings, adhesives, sealants, and cleaning products to indicate that the product contains zero grams per liter of volatile organic compounds (VOCs) in its ready-to-use form. The term is commonly encountered in construction and home-improvement contexts where indoor air quality and regulatory compliance are important.

VOCs are carbon-containing chemicals that readily evaporate at room temperature and can contribute to smog and indoor air pollution. The precise definition of VOC and the measurement method vary by jurisdiction and product category. A product labeled 0VOC typically claims compliance by testing under a specified protocol and reporting a VOC content of zero g/L, though exemptions for certain solvents or for water may apply depending on local regulations.

Achieving 0VOC usually involves reformulating formulations to minimize or eliminate traditional VOC solvents, opting for water-based components, and using non-exempt alternatives. The claimed zero VOC value refers to the product in its ready-to-use state and according to the testing method used by the certifying body; it does not necessarily imply that every ingredient is inherently non-volatile under all conditions.

Limitations include variability in regulatory definitions between regions, and the fact that some products labeled 0VOC may still release trace VOCs or contain exempt solvents not counted by certain standards. Additionally, curing or aging can alter emissions in ways not captured by a single test. Consequently, the 0VOC label should be interpreted within the relevant regulatory framework and testing methodology.
