Chesterton ARC 858 Abrasion resistant rebuilding and faring composite
Categories: Ceramic; Polymer; Thermoset; Epoxy

Material Notes: An advanced ceramic composite for the repair and protection of all metal surfaces subjected to erosion, corrosion and chemical attack. It is normally applied at a thickness of 0.15 mm (60 mils) or more. ARC 858 is 100% solids, non-shrinking. The ARC 858 is formulated for light abrasive, erosive and corrosive environments where metal loss is often repaired by more conventional and costly weld overlay. It can be used either to rebuild eroded metal surfaces or the provide a wear resistant surface which frequently outperforms the original metal or weld overlay.

Benefits:

  • High build characteristic allows for sing coat applications reducing labor costs
  • Tough resin structure resists thermal-mechanical shock
  • Outstanding adhesion insures reliable performance
  • Excellent wear characteristic extends equipment operating life
  • Convenient 4:1 mix ratio and verification of mix by color change.
  • Performs well under fluctuating chemical environments

Suggested Uses:

  • Condensers
  • Cooling Water Pumps
  • Hoppers
  • Hydro Pulpers
  • Pulp Dewatering Screws
  • Pump Casings
  • Slurry Pumps
  • Valves
  • Volutes
  • Waterboxes
  • Screw Pumps
  • Fans & Housings
  • Wear Plates
  • Pipe Elbows
  • Impellers
  • Pitted Tanks and Pipes
  • Heat Exchangers
  • Wet Scrubbers
  • Tanks and Process Vessels
  • Vacuum Pumps
