Abstract
In case of PVC floorcovering installed on high moisture content concrete substrate, it is point out of that there is a possibility of emission of newly generated VOC compounds. We already reported that hydrolysis of acrylic adhesives for tile-carpet use by alkaline moisture of concrete substrate brings about emission of 2-Ethylhexanol(2EHA) and Butanol. In this report, we investigated influence of alkaline moisture of concrete substrate on acrylic adhesives other than reported last year. As a result, the adhesive, which emitted a grate deal of 2EHA and Butanol on the test of the adhesive alone, also brought about high emission of them from PVC floorcovering construction undertaken with the adhesive. It is suggested that ester compounds in the adhesive are hydrolyzed by alkaline moisture and resulting alcohols are emitted to atmosphere through the floorcovering sheet.
