Wear Resistance Products

BoreShield ARO™ II

BoreShield ARO™ II System is a field-applied abrasion resistant outerwrap (ARO) consisting of a unique, heavy duty fiberglass reinforcement and water-activated urethane resin, designed for impact and abrasion resistance in weld seam, pipeline, directional drilling and piling applications.

The BoreShield ARO™ II System provides protection from external wear, abrasion, and impact events. The composite system includes a custom weave, heavy fiberglass tape, pre-coated with a toughened, water-activated urethane resin. The high bond strength provides resistance to shear if pipe is to be pulled and the unique weave of the reinforcement tape enables spiral applications for ease of installation on long runs of pipe or pilings. Installation entails only wrapping the composite around the area in need of protection and subsequent compression banding. The BoreShield ARO™ II System can be applied underwater without any influence on final material properties or cure rate.


  • Excellent abrasion, impact, and wear resistance
  • Installed over tapes and coatings to protect weld seams
  • Superior toughness and resistance to environmental degradation
  • Strong adhesion to pipe surfaces
  • Water activated urethane resin system fully cures to an inert fully encasing matrix
  • Requires minimal pipe preparation
  • Spiral applications provide simple pathways to targeted thickness
  • Installed with no hot work, regardless of weather conditions, pipe orientation, or local geometries
