Abstract

Some embodiments of the present disclosure relate to a roofing putty. In some embodiments, the roofing putty is a formulation that comprises at least one polysiloxane, at least one silane, and at least one filler. Some embodiments of the present disclosure relate to a system comprising the roofing putty and at least one roof substrate. Some embodiments of the present disclosure relate to a method of using the roofing putty, such as, but not limited to, by disposing the roofing putty on at least one roof substrate.

First claim

What is claimed is:

1 . A roofing system comprising:
a roof substrate; a roofing putty,
wherein the roofing putty is located on the roof substrate,
wherein the roofing putty is a formulation consisting of:
55% to 70% by weight of at least one polysiloxane based on a total weight of the roofing putty;
wherein the at least one polysiloxane comprises at least one of a mono-trimethoxy terminated polysiloxane, a silanol terminated polysiloxane, or any combination thereof;

at least one filler,
wherein the at least one filler is selected from the group consisting of fumed silicas, micro-cellulose fibers, ground silicas, kaolins, hollow glass microspheres, sands, saw dusts, flyash, pulps, rice hulls, and any combination thereof;

at least one silane,
wherein the at least one silane comprises at least one of aminoethylaminopropyltrimethoxysilane, a glycidoxypropyltrimethoxysilane, an octyltrimethoxysilane, or any combination thereof;
wherein a weight ratio of the at least one filler to the at least one silane is 1:1 to 3:1;

at least one pigment; and
at least one catalyst;

wherein the roofing putty exhibits an elongation ranging from 100% to 500%, when tested according to ASTM D2370.

2 . The roofing system of claim 1 , wherein the roof substrate comprises at least a first roof substrate and a second roof substrate, wherein the second roof substrate is parallel to the first roof substrate, wherein the roofing putty is disposed between the second roof substrate and the first roof substrate.

3 . The roofing system of claim 1 , wherein the roof substrate comprises at least a first roof substrate and a second roof substrate, wherein the second roof substrate is co-planar with or transverse to the first roof substrate, wherein the roofing putty is present on an interface between the second roof substrate and the first roof substrate.

4 . The roofing system of claim 1 , wherein the roof substrate is a plywood roof substrate, a glass roof substrate, a cellulosic roof substrate, a roofing shingle, a glass mat, a fiberglass mat, an underlayment, a roofing membrane, a roof deck, a photovoltaic (PV) panel, a modified bitumen (MODBIT) substrate, a roll good, a chimney, a polyisocyanurate (ISO) foam board, or any combination thereof.

5 . The roofing system of claim 1 , wherein the at least one polysiloxane has a viscosity of 70 cP to 300,000 cP tested according to ASTM 2196 at a temperature ranging from 20° C. to 25° C.

6 . The roofing system of claim 1 , at least one filler is present in an amount ranging from 15% to 30% by weight based on the total weight of the roofing putty.

7 . The roofing system of claim 1 , wherein the hollow glass microspheres have an average particle size ranging from 1 micron to 200 microns.

8 . The roofing system of claim 1 , at least one silane is present in an amount ranging from 5% to 20% by weight based on the total weight of the roofing putty.

9 . A method comprising:
obtaining a roofing putty; and disposing the roofing putty on at least one roof substrate;
wherein the roofing putty is a formulation consisting of:
55% to 70% by weight of at least one polysiloxane based on a total weight of the roofing putty; wherein the at least one polysiloxane comprises at least one of a mono-trimethoxy terminated polysiloxane, a silanol terminated polysiloxane, or any combination thereof;
at least one filler,
wherein the at least one filler is selected from the group consisting of fumed silicas, micro-cellulose fibers, ground silicas, kaolins, hollow glass microspheres, sands, saw dusts, flyash, pulps, rice hulls, and any combination thereof;

at least one silane, wherein the at least one silane comprises at least one of aminoethylaminopropyltrimethoxysilane, a glycidoxypropyltrimethoxysilane, an octyltrimethoxysilane, or any combination thereof;
wherein the at least one filler and the at least one silane are present in the roofing putty in a weight ratio of the at least one filler to the at least one silane ranging from 1:1 to 3:1;

at least one pigment; and
at least one catalyst;

wherein the roofing putty exhibits an elongation ranging from 100% to 500%, when tested according to ASTM D2370.

10 . The method of claim 9 , wherein the at least one roof substrate comprises a first roof substrate and a second roof substrate, the method further comprising sandwiching the roofing putty between the first roof substrate and a second roof substrate, wherein the second roof substrate is parallel to the first roof substrate.

11 . The method of claim 9 , wherein the at least one roof substrate comprises a first roof substrate and a second roof substrate, the method further comprising disposing the roofing putty at least on an interface between the first roof substrate and a second roof substrate, wherein the second roof substrate is coplanar with or transverse to the first roof substrate.
