Abstract In partnership with the IRSST and with the collaboration of particle board manufacturers, the Forest Product Processing Research and Expertise Services (SEREX) of Quebec was given the assignment to optimize formaldehyde resins currently used by modifying their formulation so that their processing would give rise to lower levels of emissions. This project involved modifying commercial urea formaldehyde resins, producing panels in the laboratory and on an industrial scale, characterizing these panels and determining the concentration of formaldehyde in the gases emitted during resin modification and panel manufacture and degassing. Not only were the formaldehyde emissions reduced, but the quality of the panels was also slightly improved. The immersion tests also showed that the panels thus produced were more water resistant than the panels manufactured using conventional resins.
