Study on the VOC Emission from Adhesive (2)

Abstract

In this study VOC emission from two same wood-based materials glued with Epoxy adhesives (EP) contained a slight amount of toluene, xylene, ethylbenzene and styrene was measured by using a small chamber method according to JIS A 1901. Even more, VOC emission until 1day during setup specimen in the chamber as "the early VOC emission" was measured also, although this method didn't establish JIS A 1901. The result shows that the early VOC emission was a lot. Especially, the maximum time of emission curves was late in proportion with density of fiberboard. On the other hand, VOC emission behavior for PW and LVL was different from that of fiberboard (MDF etc.) , they have been diffused persistent a slight amount of VOC during long term. The reason was depended on the adhesive layer of PW and peeling veneer as wood element.
