ARC 858 Datasheet

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 1,5 mm (60 mils) or more. ARC 858 is 100% solids, non-shrinking and is grey in color.

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 frequently outperforms the original metal or weld overlay.

Composition - Polymer/Ceramic Composite
Matrix - A two component, crystallization resistant, modified epoxy resin structure reacted with an aliphatic curing agent.

Reinforcement - A proprietary blend of fine ceramic particles designed to achieve a smooth erosion and corrosion resistant surface.

Packaging
Material is available in five package sizes: 250 g, 400 ml cartridge, 1 kg, 4,5 kg and 24,8 kg. Each package contains pre-measured containers (Part A and Part B). A mixing tool, and application instructions are also included.

Chemical Resistance
Recommended for exposure to moderate concentrations of acids, alkalies, bleaches, and other chemicals. Please refer to the ARC Chemical Resistance Charts for a comprehensive list of chemicals and associated exposure ratings at ambient temperature. Post curing will improve chemical resistance; contact ARC Technical Services for elevated temperature exposure.
