Stop It® Pipe Repair System

XCorr® Flat Patch

XCorr® Flat Patch - Leak Sealing

XCorr® Flat Patch is a carbon-epoxy composite repair system designed for sealing applications where localized repair is needed or full pipe wraps are impractical. XCorr® Flat Patch utilizes a premeasured 2-part novolac epoxy system combined with triaxial carbon fiber reinforcement fabrics and a technical felt to provide superior leak sealing capacity on flat surfaces. XCorr® Flat Patch is recommended for pressure applications up to 1,500 psi (105 kg/cm2) with a built in 4:1 safety margin. Return to service at pressure may be accomplished in ~5 hours for temperatures above 75°F.

Attributes

  • Novolac epoxy resin yields exceptional chemical resistance, 100% solids, No VOCs
  • Cartridge dispensing minimizes waste, ensures complete mixing, and manages pot life
  • Primary technical felt layer ensures interfacial wetting and highest pressure performance
  • Outstanding compressive, flexural, and adhesive bond strength
  • Accelerated cure times are possible with annealing of the installed repair
  • Carbon fiber composite repair system safely and quickly restores operations up to 1,500 psi, and provides localized corrosion inhibition
