ARC S1 Datasheet

Source: A.W. Chesterton Company

An advanced composite formulated to protect metal surfaces from corrosion and chemical attack. It is normally applied at a thickness of 250 microns (10 mils) per coat. Non-shrinking, 100% solids. Colors are Light Gray and Blue.

ARC S1 is a low viscosity high performance composite lining that is designed to be spray applied but may also be applied by roller or brush. As a one coat system, it functions as a corrosion resistant primer for many high performance coatings. ARC S1 yields excellent barrier properties for long-term corrosion and chemical resistance in immersion exposures when used in a multicoat application. The cured ARC S1 provides a high gloss surface with unrivaled adhesion and resistance to corrosion.

COMPOSITION - Polymer/ Surface Modified Mineral Composite
Matrix -
A two component, modified epoxy resin structure reacted with a polyamidoamine curing agent.
Reinforcement - A proprietary blend of surface modified mineral reinforcements designed to provide resistance to permeation, chemical attack and corrosion.

Based on a 250 µ (10 mils) thickness:
4 liters will cover 16 sq. meters (170 sq. ft.)
16 liters will cover 64 sq. meters (678 sq. ft.)
To calculate the kilograms required for a given application use the appropriate formula below:
1.5 (g/cc) x Area (m2)x Average Thickness (mm) = kg
3.5 x Area (ft2) x Average Thickness (inches) = kg

Chemical Resistance
Recommended for exposure to low 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.
