MEASUREMENT OF REACTION PRODUCT EMITTED FROM FLOORING MATERIAL Influence of adhesives for flooring on 2-ethyl-l-hexanol emission

The emission mechanism for 2-ethyl-1 -hexanol (2E1H) is considered that water with high pH in sub-floor material reacts to compounds containing the 2-ethyl-1 -hexyl group in PVC flooring and the adhesive. In this study, PVC floorings are attached using various adhesives to a self-leveling sub-floor material that contains water, and their 2E1H emission rates are measured. Furthermore, the components of the adhesives are analyzed using chemical analysis. It is found that the 2E1H emission rate from the floor is affected by the type of adhesive. On the other hand, some components in the adhesives may suppress the hydrolysis of testers.
