SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT
SURFACE PREPARATION:
Metal surfaces are to be cleaned and degreased then abrasive
blasted with chloride free abrasive. Exterior applications to
SSPC-SP-10 near white metal finish minimum 3 mil profile.
Immersion applications to SSPC SP-5 white metal, 3 to 5 mil
profile. Grind flat all burrs, weld seams, radius sharp edges.
Fresh blasted surfaces to be rebuilt as quickly as possible to
prevent oxidation of surface. Prime surface with ARCOR™ARCRETE
(unfilled) or ARCOR™ EE-31 or EE-031.1
Concrete surfaces should be
degreased. Degreased surface shall be high pressure washed, acid
etched and high pressure washed again so surface is clean and
free of all grease, oils and surface laitance. Existing coatings
should be abrasive blasted to clean concrete. Prime surface with
ARCOR™ARCRETE (unfilled) or ARCOR™EE-10, EE-70, EE-79
MIXING:
Thoroughly mix Activator into Base with mixing stick or drill
with low speed mixing blade scraping sides and bottom of
containers or mixing board. Mix by Volume 2 parts Base to 1 part
Activator or by weight, 100 grams base to 44.9 grams activator.
Mix thoroughly to produce an even colored and streak-free
material.
Add concrete mortor at 32 lbs. (14.5) per gallon of mixed resin.
Increase or decreased amount of mortor as conditions require.
THINNING: Never thin.
APPLICATION:
Use towel, heavy squeegee, caulking gun or putty knife. Work
material into profile of substrate to achieve maximum adhesion
and to remove any entrapped air. Contour to correct form with
putty knife or plastic applicator. Large holes can be bridged
with glass cloth or metal. Material can be shaped by
sanding/grinding before full cure.
APPLICATION TEMPERATURE:
Material: Keep between 55 to 95ºF(17 to 35ºC). Substrate : Keep
between 45 to 105ºF(7 to 40ºC). The difference in temperature of
the substrate and the material should never exceed 10ºF (5ºC).
Substrate shall be a minimum of 5ºF (3ºC) above dew point. Do
not apply if relative humidity exceeds 90%. If necessary heat
metal prior to surface preparation using electric heater or heat
lamp. Never use gas, oil or kerosene heaters as they will leave
a greasy residue on metal surface. For best results keep all
material in warm area overnight (75ºF to 24ºC) for easy mixing.
If necessary base component of material can be heated by microwave
for 30-45 seconds for a 1 KG Base unit or by warm water bath.
Heat activator by warm water bath only. If necessary let material
cool before application.
OVERCOAT/CURE TIME:
Recoat between 6 to 12 hours at 77ºF (35ºC). If overcoat window
is exceeded abrade surface with course sandpaper, grinder or
brush blast. Full cure before immersion seven days at 77ºF. Add
1 day additional cure time for each 10ºF below 77ºF. Subtract15
hours of cure time for each 10ºF above 77ºF. Force cure with
heat for best performance: 12 hours at 120ºF(49ºC). Do not use
gas or kerosene heaters.
CLEAN UP:
Clean up tools immediately after use with
M.E.K. or similar
WARNING: Base contains
epoxy resin. Activator contains alkaline amines, a strong
sensitizer. May cause skin irritation, sensitization or other
allergic responses. Use with good ventilation, particularly if
heated or sprayed. Prevent all contact with skin or eyes. Wear
protective clothing, goggles, gloves or barrier creams. Keep
containers closed when not in use. Wash thoroughly after
handling. In case of skin contact immediately wash with soap and
water. In case of eye contact, flush with water for 15 minutes.
If irritation persists seek medical attention.
