ABSTRACT:
An improved adhesive roofing tape is based on a combination of brominated butyl rubber and EPDM. A non-diene block terpolymer is interspersed in the cross-liked polymer network. A plasticizer, a phenolic tackifier, a high melting point non-phenolic tackifier and a low melting point non-phenolic tackifier are included to provide resiliency and permanent tack at low temperatures. A method of making the adhesive roofing tape is also provided.
