arc 855 chemical and corrosion resistant coating is applied to repair an offshore riser pipe

An offshore riser pipe is in need of repair. Before the Chemical and Corrosion Resistant Coating can be applied, the steel surface is prepared using a Bristle Blaster

Steel surface of offshore riser pipe is repaired with ARC 855 chemical and corrosion resistant coating

The healthy area is masked and the Chemical and Corrosion Resistant Coating is applied to the damaged area

Aggregate is added to the wet ARC 855 chemical resistant coating to ensure greater adhesion when further layers are applied in this repair project

An additional layer of aggregate is applied while ARC 855 is wet. This will ensure greater adhesion when the Rubber Repair and Protection solution is applied to the outer layer

ARC 855 features moderate ceramic reinforcement to protect equipment of all sizes from corrosion, erosion and aggressive chemical attacks

ARC 855 effectively protects equipment and structures of all sizes from chemical attack and corrosion

ARC 855 features moderate ceramic reinforcement to protect equipment of all sizes from corrosion, erosion and aggressive chemical attacks

ARC 855 is a chemically-resistant thin film coating.

It features moderate ceramic reinforcement to protect equipment from corrosion, erosion and aggressive chemical attacks.

ARC 855 Chemical and Corrosion Resistant Coating is a 100% solids, no VOC application. It produces a high gloss, low drag surface which results in an improved material flow and enhances efficiency. This low viscosity coating delivers an abrasion resistant surface that extends equipment life.

Other features and benefits of this high performance technology includes its high adhesive strength which prevents under-film corrosion.

There’s no shrinkage on curing of this chemical resistant application and it resists permeation. It is an effective, easy-to-use solution which reduces down time.

ARC 855 is applied at a minimum thickness of 250 μm (10 mil). Typical application thicknesses range from 375-500 μm (15-20 mil) per
coat. When used alone, this chemical resistant coating should always be applied in a minimum of two coats.

ARC 855 Chemical and Corrosion Resistant Coating is designed to:

  • Upgrade new and old equipment exposed to corrosion or chemical attack
  • Extend the operating life of equipment and reduce spare parts
  • Replace traditional coatings, special alloys, engineered plastics, ceramics, etc.
  • Offer outstanding adhesion which insures reliable performance with no undercutting or under film corrosion
  • Deliver a high gloss, low drag surface which improves material flow and enhances efficiency
  • Safely, easily and effectively be applied by roller or brush

ARC 855 Application Areas Include:

  • Pump Casi​ngs
  • Bins and Silos
  • Transport Screws
  • Impellers and blades
  • Hoppers
  • Tanks and Vessels
  • Heat Exchangers
  • Waterboxes
  • ​Valves
