Emissions of volatile organic compounds (VOCs) from oriented Strandboard (OSB) samples were measured. The OSB samples were from a new house constructed using structural engineered panels. The OSB samples were tested: 1) uncoated; 2) coated with oil-based primer; 3) coated with topcoat latex; and 4) coated with both. The highest total VOC emissions were measured from the primer-coated OSB samples. The laboratory results indicate that terpens were found mainly in the uncoated OSB samples (9.5% of total VOC emissions represented alpha-pinene) while N-decane (18%) and N-undecane (36%) are the most abundant components in the oil-based primer used as coating. The water-based latex was found to contain mainly benzene derivatives (30%). The experimental results and information from relevant studies were combined for the toxicological evaluation of the OSB and coatings. The uncoated isocyanate-bonded OSB had very low VOC emissions through the 28-day test period. All tested materials met the "very low emitting materials" benchmark of widely referenced total VOC evaluation procedure after 3 and 28 days.
