A unique cold-applied roofing glue made with "Heart of Texas" Asphalt®, a high performance plasticizing adhesive resin and other special SWEPCO ingredients. Safer and easy to install, it provides a super strong bond between non-nailable roof decks and successive layers of roof membrane. Can also be used to bond asphalt roll roofing and other roofing felt. Unlike rigid bonding materials such as hot asphalt, Adhesive #9 gives a flexible yet stable bond which helps keep the membrane from cracking, splitting and tearing.
