Field hardening pipe liner |
| abstract |
Discloses a liner for repairing a damaged pipe, e.g., an underground sewage or a gas pipe. The liner comprises a TPU coating on a fibrous mat of a nonwoven fabric. The TPU coating is a high temperature resistant polyester TPU that allows the epoxy resin / amine to saturate on the nonwoven fabric and to allow curing initiated by the use of steam or hot water. As the liner is cured inside the pipe, the cured epoxy resin converts the liner from a flexible state to a rigid state. The TPU containing liner may also be used with thermosetting resins other than epoxy resins, such as polyester resins and vinyl ester resins. |
