Abstract

The present disclosure relates to multi-layered elastomer-based liners. In at least one embodiment, a coated substrate includes a substrate and a first elastomer coating disposed on the substrate. The first elastomer coating is substantially free of sulfur and includes a first elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The coated substrate includes a second elastomer coating disposed on the first coating. The second elastomer coating includes a second elastomer selected from the group consisting of a polyurea, a polyurethane, a polyurea-polyurethane copolymer, and combinations thereof. The first elastomer is the same as or different than the second elastomer and at least one of the first elastomer or the second elastomer is a polyurea-polyurethane copolymer.
