Abstract

Claims (27)

1 . A method of installation comprising:

obtaining a composition,

wherein the composition comprises:

a polymer,

wherein the polymer comprises at least one of a polysiloxane, a silyl-terminated polymer, or any combination thereof; and

1% to 50% by weight of a magnetic-responsive additive based on a total weight of the composition;

obtaining a roller device,

wherein the roller device comprises a roller;

wherein the roller contains a magnetic array,

wherein the magnetic array is configured to apply a directional magnetic field;

contacting the roller of the roller device with the composition, so as to:

spread the composition onto at least a portion of a surface of a roofing substrate; and

magnetically align at least a portion of the magnetic-responsive additive in a horizontal orientation; and

curing the composition, so as to obtain a cured roofing membrane.

2 . The method of claim 1 , further comprising, before the contacting step, applying the composition to the roller of the roller device.

3 . The method of claim 1 , further comprising, before the contacting step, applying the composition to the surface of the roofing substrate.

4 . The method of claim 1 , wherein curing comprises at least one of moisture-curing, heat curing, or any combination thereof.

5 . The method of claim 1 , wherein the composition comprises:

90% to 99% by weight of the polymer based on the total weight of the composition; and

1% to 10% by weight of the magnetic-responsive additive based on the total weight of the composition.

6 . The method of claim 1 , wherein the composition comprises:

95% to 99% by weight of the polymer based on the total weight of the composition; and

1% to 5% by weight of the magnetic-responsive additive based on the total weight of the composition.

7 . The method of claim 1 , wherein the magnetic-responsive additive is magnetically aligned in the horizontal orientation while the composition is spread onto at least a portion of the surface of the roofing substrate.

8 . The method of claim 1 , wherein the magnetic-responsive additive comprises at least one of graphene, carbon nanotubes, graphene oxide, metal dichalcogenides, graphite, or any combination thereof.

9 . The method of claim 1 , wherein the magnetic-responsive additive has a form of at least one of flakes, platelets, sheets, tubes, ribbons, rods, tubes, whiskers, fibers, spheres, cubes, or any combination thereof.

10 . The method of claim 1 , wherein a sufficient amount of the magnetic-responsive additive is magnetically aligned, by the magnetic array, in the horizontal orientation, so as to result in a cured roofing membrane having a reflectivity that is at least two times greater than a reflectivity of a cured control roofing membrane which does not comprise the magnetic-responsive additive.
