Adhesive for bonding EPDM rubber roofing membrane and bonding method employing same

摘要

This invention relates to an adhesive for use with elastomeric substrates such as EPDM roofing materials, a method for splicing elastomeric substrates using splice adhesives and a laminate. The adhesive of this invention combines butyl rubber crosslinked after polymerization, halogenated butyl rubber, tackifying resin, and an isocyanate partially reacted with a diamine in a shelf stable product which rapidly forms strong bonds resistant to heat and humidity.
