- 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 (ethylene propylene diene terpolymer)roof membranes. Four Phase III tasks investigated the effects of: (I) elevated test temperatures, (II) elevated temperature exposure prior to loading, (III) exposure to industry-developed protocols (i.e., Rubber Manufacturers Association and SPRI), and (IV) cold temperature preparation on peel creep-rupture response and on peel strength. Task (V) examined shear testing. Two commercial tape systems (i.e., tape and primer) and one liquid adhesive were applied to well-cleaned EPDM rubber in fabricating specimens. For each task, comparisons of the creep-rupture responses and strengths of tape-bonded and liquid-adhesive-bonded samples were made.
