Abstract
This report presents the results of Phase III research of an industry-government consortium study to develop nonproprietary data on the performance of tape bonded seams of EPDM roof membrne. Four Phase III tasks investigated the effects of elevated test temperatures; elevated temperature exposure prior to loading; exposure to industry developed protocols and cold temperature preparation on peel creep rupture response and on peel strength. Two commercial tape sytems (i.e., tape and primer) and one liquid adhesive were applied to a well cleaned EPDM rubber in fabricating specimens. For each task, comparisons of the creep rupture responses and strenghts of tape bonded and liquide adhesive bonded samples were made. The conclusions are reported in this report.
