Abstract
Adhesive-less roofing systems are provided. A roofing system comprises a roofing substrate and at least two roofing membranes. The at least two roofing membranes are located on the roofing substrate. The at least two roofing membranes are partially overlapping, so as to form an overlapping portion. Each of the at least two roofing membranes independently comprises a crosslinked polymer and a boron-containing compound. Related roofing materials and related methods, among other things, are also provided.
Claims14
A roofing system comprising:
- a roofing substrate;
- and
- at least two roofing membranes,
- wherein the at least two roofing membranes are located on the roofing substrate;
- wherein the at least two roofing membranes are partially overlapping, so as to form an overlapping portion;
- wherein each of the at least two roofing membranes independently comprises:
- 30% to 90% by weight of a crosslinked polymer,
- wherein the crosslinked polymer comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof;
- 1% to 30% by weight of a silicone fluid;
- and
- 1% to 15% by weight of a boron-containing compound,
- wherein the boron-containing compound comprises at least one of a boric acid, a boronic acid, a pyroboric acid, a boronate ester, a borate ester, a borosiloxane oligomer, a borosiloxane polymer, a boric anhydride, a boride, or any combination thereof.
