ARC 855 Datasheet

An advanced ceramic composite formulated to protect equipment from aggressive chemical attack, corrosion, and erosion. The product is a low viscosity composite that is easily applied by brush or roller. ARC 855 may be applied at a minimum thickness of 250 microns (10 mils) per coat. Non-shrinking. 100% Solids. Colors are black and gray.

ARC 855 may be used alone, or in conjunction with other ARC composites. This two-coat system provides extended wear and predictable preventative maintenance. The cured ceramic composite provides outstanding chemical and abrasion resistance with a high gloss finish.

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

Reinforcement - A proprietary blend of ceramics, selected to achieve a smooth, brush applied, wear resistant surface.

Packaging
Material is available in three package sizes: 1 kg, 4,5 kg and 15 liter. Each package contains two premeasured containers (Part A and Part B). A mixing tool, brush and application instructions are enclosed with the 1 kg and 4,5 kg kits. The 15 liter kit contains only application instructions.

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.
