ARC CS2
PRODUCT DATA SHEET
Description
Packaging
An advanced composite formulated to protect concrete surfaces from mild
chemical attack. It is normally applied at a thickness of 250 -375 microns
(10 - 15 mils) per coat. Non-shrinking. 100% solids. Color is Light Gray.
ARC CS2 is a low viscosity high performance composite coating that can be
easily applied by notched squeegee, brush, roller, or spray equipment. ARC
CS2 yields excellent barrier properties for long-term chemical resistance in
immersion exposures. The cured ARC CS2 provides a high gloss surface with
unrivaled adhesion to dry and wet concrete.
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, and
chemical attack.
Suggested Uses
• Water and Sewage Tanks
• Secondary Containment
• Pipeline Coatings
• Clarifier Tanks
• Water Intakes and Dams
• Cooling Towers
• Turbine Decks
• Industrial Floors
Material is available in two sizes: 4 and 16 liter kits. Each package contains
two pre-measured containers (Part A and Part B). A mixing tool, brush and
instructions for use are enclosed with the 4 liter kit. The 16 liter kit contains only
application instructions.
Coverage
Based on a 375 µ (15 mils) thickness:
4 liters will cover 10.7 sq. meters (113 sq. ft.)
16 liters will cover 42.7 sq. meters (452 sq. ft.)
To calculate the kilograms required for a given application use the appropriate
formula below:
1.3 (g/cc) x Area (m2) x Average Thickness (mm) = kg
3.1 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.
Benefits
• Dramatically outlasts conventional paints and coatings.
• Long pot life allows for ease of use.
• 100% solids, no shrinkage on cure.
• Outstanding adhesion insures reliable performance.

Notes:
1. Since ARC CS2 is an epoxy-based composite, it is susceptible to color fade and chalking as a result of UV exposure. This reaction is limited to the exposed surface and does not adversely impact long-term
performance of the composite.
2. Due to minor color variations in certain critical raw materials, slight variations in color between different lots of ARC CS2 may occur.
Surface Preparation
Proper surface preparation is important for the long term performance
of this system. For detailed information on surface preparation and
application, please refer to ARC Composites for Concrete Application Manual.
Generally new concrete must be cured for a minimum of 28 days.
Remove all grease, oils, and grime by washing with an emulsifying alkaline
waterbase cleaner. All surface contaminants including old coatings, chemical
salts, dust, loose concrete, and the laitance layer must be removed. This
is best accomplished by hydro-blasting, steel shot-blasting, scarifying, or dry
abrasive blasting. The resulting surface must be structurally sound and free
of all contaminants. Surface dampness is acceptable; standing water is not.
For slab on grade applications, a vapor barrier is recommended.
If no vapor barrier is present, check for vapor transmission.
Mixing
To facilitate mixing and application, material temperatures should be
between 21°C - 32°C (70°F - 90°F). Each kit is packaged to the proper mix
ratio. If further proportioning is required, the kit should be divided to the
correct mix ratio.

Prior to mixing ARC CS2, pre-mix Part A to suspend any settled
reinforcements. When applying by hand, add Part B to Part A. Mix by hand
for 1 minute. Shift a small portion of this mix back to the Part B container and
scrape the walls of this container to remove all traces of residue. Add this
portion back to the Part A container. Continue to mix product until product
is uniform in color and consistency, no streaks. Power mixing should be
accomplished with a variable speed, high torque, low speed mixer with a
non-air entraining mix blade such as a “Jiffy” blade. Do not mix more product
than can be applied within the stated working time.

Apply initial pass at 75 -125 microns (3 - 5 mils). Build successive passes to
achieve final first coat desired thickness. Vertical or overhead applications
will result in reduced film thickness. To compensate additional coats are
recommended.
Multiple coat applications of ARC CS2 may be accomplished, without
additional surface preparation, as long as the film is free of contamination
and has not cured beyond the stage stated as Light Load in the Curing
Schedule chart below. If this period is exceeded, light abrasive blasting or
sanding is required followed by removal of abrasive residues.

Force curing at 65°C (150°F) after material has reached Foot Traffic will accelerate cure time
to 8 hours plus Foot Traffic time.
Clean Up
ARC CS2 cures to a solid mass in a very short period of time. All clean up
activities must be carried out as soon as possible to prevent material
hardening onto the tools. Use commercial solvents (Acetone, Xylene, Alcohol,
Methyl Ethyl Ketone) to clean tools immediately after use. Once cured the
material would have to be abraded off.
Storage
Store between 10°C (50°F) and 32°C (90°F). Excursions beyond this range
which may occur during shipping are acceptable. The shelf life is two years in
unopened containers. Settling and reinforcement separation may occur over
time or at elevated storage temperatures. Reconstitute prior to use by mixing
individual components before mixing Part A with Part B.
Safety
Before using any product, review the appropriate Material Safety Data Sheet
(MSDS) or Safety Sheet for your area. Follow standard confined space and
entry work procedures, if appropriate.
The chart above defines the practical working time of ARC CS2, starting from when mixing begins.
Application
ARC CS2 may be applied by notched squeegee, spray system, brush,
or roller using a lint free nap roller such as mohair.
When applying ARC CS2 the following conditions should be observed:
Film thickness range per coat
250 µ (10 mils) - 375 µ (15 mils)
Application temperature range
10°C (50°F) - 35°C (100°F) (substrate)
For maximum protection against immersion or spills, a 2 coat system
is recommended.
ARC CS2 may be spray applied by airless spray equipment without solvent
dilution. Please consult your local ARC specialist for equipment specifications
and recommendations.
