SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT
SURFACE PREPARATION:
Metal surfaces are to be cleaned and degreased when 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, 3-5 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 the surface. For larger surface areas with
ferrous metals apply a primer layer of ARCOR™ EE-31 or EE31.1 to
prevent oxidation of the surface and allow time for proper
rebuilding of the damaged area.
Concrete surfaces should be
degreased if oil and grease contamination is present. 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 with ARCOR™ EE-70,
EE-79, EE-10.
MIXING:
Thoroughly mix Activator into Base with mixing stick or drill
with low speed mixing blade scraping sides and bottom of
container or mixing board. Mix by Volume 2 parts Base to 1 part
Activator or by weight 100 grams base to 50 grams activator.
Mix thoroughly to produce an even colored, streak-free material.
THINNING: Never thin.
APPLICATION:
Use heavy plastic squeegee 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. If mold or form is used, coat its surface
with a release agent to prevent adhesion of the material.
Machining is possible using carbide tipped tools. Grinding is
possible if done within 14 hours of application at 77ºF, 25ºC
(add 1-1/2 hour for each 10ºF below 77º, subtract 1 hour for
each 10º above 77ºF). Large holes and cracks can be bridged with
glass or metal cloth.
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
the 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+) for ease of 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 activated by warm water bath only. If necessary
let material cool before application.
OVERCOAT / CURE TIME:
Recoat while material is still soft, between 6 to 14 hours
at 77ºF, 25ºC. If overcoat window is exceeded abrade surface
with course sandpaper, grinder or brush blast. Full cure before
immersion 72 hours at 77ºF. Add 1 day additional cure time for
every 10ºF below 77ºF. Subtract 15 hours of cure time for each
10ºF above 77ºF. Force cure with heat for best performance for 1
hour at 200ºF, 93ºC, 12 hours at 120ºF at 120ºF, 49ºC.
CLEAN UP: Clean 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.
