Patent ID: 6967178

Claim:
An elastic laminate, comprising: at least one facing sheet; and a plurality of strands of a melt-tank processable elastomeric construction adhesive composition self-adhered to the at least one facing sheet; the elastomeric adhesive composition including at least 55% by weight of a base polymer selected from the group consisting of polystyrene-polyethylene-polypropylene-polystyrene (SEPS) block copolymer, styrene-isoprene-styrene (SIS) block copolymer, styrene-butadiene-styrene (SBS) block copolymer, thermoplastic polyurethane, ethylene-propylene-diene copolymers, and combinations thereof, and at least 30% by weight of a high softening point tackifier resin comprising at least one type of hydrocarbon selected from the group consisting of petroleum distillates, rosin, rosin esters, polyterpenes derived from wood, polyterpenes derived from synthetic chemicals, and combinations thereof, and having a softening point of at least 80 degrees Celsius and a viscosity of at least 1500 cps at 182 degrees Celsius; wherein the elastomeric construction adhesive composition has a viscosity of about 5,000 to 80,000 cps at between 177 and 204 degrees Celsius.
