SURFACE
PREPARATION:
Steel surfaces are to be abrasive blasted with chloride free
abrasive. Exterior applications to SSPC SP-6 Commercial gray
metal finish. Immersion applications to SSPC SP-5 white metal.
Grind flat all burrs, weld seams, radius sharp edges. Fresh
blasted surfaces to be primes with ARCOR™ EE-121.
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-121.
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 3 parts Base to 1 part Activator or by weight 100 grams base to 41 grams activator. Mix thoroughly to produce an even colored and streak-free material.
THINNING:
Never thin
APPLICATION:
Brush: medium to stiff bristle of suffi cient quality that bristles do not pull out and stick in coating. Trim or tape to <1” nap.
Roller: good quality 1/8” nap.
Plural Spray: .029-.031 tip, 3,000-3,500 PSI, Heat to 130ºF Base, 110ºF Activator.
Airless Spray: Not Recommended
Conventional Spray: Not Recommended
All spray equipment should employ traps to prevent water and oil from contaminating coating
and screens to prevent particulate contamination.
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+, 24ºC) 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 activator by warm water bath only. If
necessary let material cool before application.
OVERCOAT/CURE TIME:
By brush, roller or squeegee recoat while material is still soft, but tack-free, between 1-3 hours at 77ºF(25ºC). IMPORTANT:
It is highly recommended that prior to overcoat that the prior coat be fully wiped with MEK or Acetone. If overcoat window is
exceeded abrade surface with course sandpaper, grinder or brush blast and wipe with MEK or Acetone. By spray application
recoat between 1/2-1 hours at 77ºF. Full cure before immersion 72 hours at 77ºF. Add 1 hours additional cure time for each
10ºF below 77ºF. Force Cure with heat for best performance for 2 hours at 250ºF(121ºC).
CLEAN
UP:
Clean tools immediately after use with M.E.K., Acetone or similar. ARCLEAN or Isopropyl Alcohol can be used
in solvent restricted areas
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.
