Patent ID: 8297008

Claim:
An assembly for securing a solar module to a roofing substrate, the roofing substrate having at least one pair of parallel, spaced apart ridges, the assembly comprising: a spacer having a top surface and a bottom surface, wherein the spacer has a first dimension equal to a distance between one of the pair of ridges and another of the pair of ridges and the spacer has a second dimension greater than a distance between a bottom of the at least one pair of ridges and a top of the at least one pair of ridges; a first adhesive layer having a first surface and a second surface, wherein the first surface is in contact with at least a portion of the top surface of the spacer and the second surface is in contact with at least a portion of the solar module; a second adhesive layer having a first surface and a second surface, wherein the first surface is in contact with at least a portion of the bottom surface of the spacer and the second surface is in contact with at least a portion of the roofing substrate; and wherein the assembly is disposed between the at least one pair of ridges to adhere the solar module to the roofing substrate; and wherein the first and second adhesive layers comprise: an uncured rubbery polymer blend present in an amount from about 10% to about 60% by weight; at least one of a compatible tackifier present in an amount from about 5% to about 25% by weight or a curing agent blend present in an amount from about 1% to about 5% by weight, the compatible tackifier comprising a phenolic tackifier resin, the curing agent blend comprising at least one of a cure accelerator, a sulfur activator, and a curing vulcanizing agent; and a polybutene homopolymer present in an amount from about 20% to about 60% by weight.
