Chesterton’s ARC 858  is an advanced ceramic composite for repair and protection of all metal surfaces subjected to erosion, corrosion and chemical attack. Easily troweled on. Its non-slumping consistency makes this ideal for applications involving fluid flow equipment (pumps and valves).

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 to provide a wear resistant surface which outperforms the original metal or weld overlay. Use to rebuild damage prior to overcoating with ARC 855.
