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.
Claims10
A roofing system comprising:
- a first roof substrate;
- a protruding member,
- wherein the protruding member protrudes from the first roof substrate;
- and
- a roofing putty,
- wherein the roofing putty is located at an interface between the first roof substrate and the protruding member,
- 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.
