a substrate;
wherein the substrate comprises at least one of a scrim, a fiberglass mat, a fabric, a glass mat, or any combination thereof; and
a coating on the substrate,
wherein the coating comprises:
5% to 98% by weight of a polymeric material based on a total weight of the coating,
wherein the polymeric material comprises a polymer A and a polymer B,
 wherein the polymer A and the polymer B are different,
 wherein the polymer A is crosslinked,
 wherein the polymer B is not crosslinked,
 wherein the polymer B is not bonded to the polymer A,
 wherein the polymer B is interlaced throughout a polymer network of the polymer A, so as to form an interpenetrating polymer network; and
2% to 95% by weight of at least one filler based on the total weight of the coating,
wherein the coating has a thickness of 20 mils to 200 mils;
