3526
Low Temperature Multi-Purpose Epoxy Resin
PRODUCTION DESCRIPTION
General Polymers 3526 LOW TEMPERATURE MULTI-
PURPOSE EPOXY RESIN is a two-component, high
solids epoxy resin designed for use in concrete toppings,
slurries, machine grouting, beam repair and preservation
of concrete where rapid cure, moisture tolerance and
chemical resistance are important. Systems using 3526,
3526P LOW TEMPERATURE MULTI-PURPOSE EPOXY
RESIN can be installed at temperatures as low as 35F.
3526 LOW TEMPERATURE MULTI-PURPOSE EPOXY
RESIN is also suitable for pressure injection installations
involving the preservation and rebuilding of cracked or
in certain cases, delaminated concrete. The low viscosity
and excellent wetting of 3526 LOW TEMPERATURE
MULTI-PURPOSE EPOXY RESIN allows rapid
penetration and bonding in minor hairline cracks or wide
openings up to 1/8" - 1/4". It is also designed for use in
inclement weather conditions and can be applied to
damp, cold concrete surfaces.
ADVANTAGES Low temperature cure, down to 35F Blush resistant Low viscosity Chemical resistant Fast cure time Can be used as a primer, binder, and seal coat
TYPICAL USES
3526 LOW TEMPERATURE MULTI-PURPOSE EPOXY
RESIN can be used in cool areas where standard cure
epoxies wont cure. In addition, it can be used in areas
where a rapid cure and chemical resistance is important.
LIMITATIONS Slab on grade requires vapor/moisture barrier. Substrate must be structurally sound, dry and free
of bond inhibiting contaminants. During installation and initial cure cycle substrate
and ambient air temperature must be at a minimum
of 35F. Substrate temperature must be least 5F
above the dew point (for lower temperature
installation contact the Technical Service
Department). Lower temperatures will prolong cure times.
LIMITATIONS (CONTINUED) 3526 will discolor over time and with UV exposure.
Avoid light colors when aesthetics are a priority. 3526 has a low pigment level when used as a coating,
two coats (10-12 mils) are required to achieve complete
hiding. Higher temperatures will shorten cure times. Do not apply over frozen substrates.

SURFACE PREPARATION
Proper inspection and preparation of the substrate to receive
resinous material is critical. Read and follow the Instructions
for Concrete Surface Preparation (Form G-1) for complete
details. GP TDS 3526/7

STORAGE / APPLICATION MATERIAL DELIVERY AND STORAGE
Store materials in accordance instructions, with seals and
labels intact and legible. Keep resins, hardeners, and
solvents separated from each other and away from sources
of ignition. One year shelf life is expected for products stored
between 50ºF - 90ºF. APPLICATION INSTRUCTIONS
1. Premix 3526A (resin) using a low speed drill and Jiffy
blade. Mix for one minute and until uniform, exercising cau-
tion not to whip air into the material.
2. Add 3 parts 3526A (resin) to 1 part 3526B (hardener) by
volume. Mix with low speed drill and Jiffy blade for three
minutes and until uniform.
3. 3526 application varies upon usage.
Note: Epoxy materials will appear to be cured and dry
to touch prior to full chemical cross linking. Allow
epoxy to cure 2-3 days prior to exposure to water or
other chemicals for best performance.
CHEMICAL RESISTANCE
For comprehensive chemical resistance information, consult
the Chemical Resistant Guide and contact the Technical
Service Department.
Cleanup
Clean up mixing and application equipment immediately
after use. Use toluene or xylene. Observe all fire and health
precautions when handling or storing solvents.
Safety
Refer to the MSDS sheet before use. All applicable federal,
state, local and particular plant safety guidelines must be
followed during the handling and installation and cure of these
materials.Safe and proper disposal of excess materials shall
be done in accordance with applicable federal, state, and
local codes.
Maintenance
Occasional inspection of the installed material and spot re-
pair can prolong system life. For specific information, con-
tact the Technical Service Department.
