APPLICATION SHEET

REVISED 3/2014

SEE MATERIAL SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT

SURFACE PREPARATION: Steel surfaces are to be abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish. Immersion applications to SSPC SP-5 White metal 3 to 5 mil profile. Grind flat all burrs, weld seams, radius sharp edges. Fresh

blasted ferrous surfaces to be should be coated immediately with ARCOR™ 1321 to prevent oxidation of surface. For very large areas

ARCOR™ EE-80 can be used as a pre-prime to help hold the blast.

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™ 1321.

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 35 grams activator. Mix thoroughly to produce an even colored and streak-free material.

THINNING: Not Advised; but if necessary add 5% by volume(6 oz/gal.) Acetone or MEK to extend pot-life and/or thin for cold weather application.

APPLICATION: All spray equipment should employ traps to prevent water and oil from contaminating coating and screens to prevent particulate contamination.

Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating. Trim or tape to <1” nap. Roller:  good quality 3/8” nap.

Plural Spray: .027-.035 tip, 2,000-3,500 PSI, Heat to 110ºF Base, 90ºF Activator. 30 mesh screens. Heated hose @ 120ºF Airless Spray:  .027-.035 tip, 4,000-4,500 PSI(45:1). Add 6-oz/gal of MEK or Acetone.(Caution: Short Pot-Life) Conventional Spray:  Not Recommended.

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 seconds for a 1 MK 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 re-coat while material is still soft, but tack-free, between 1-12 hours at 77ºF (25ºC). If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. By spray application a single coat to 20 mils is recommended. For multiple coats, re-coat between 1-12 hours at 72ºF. Full cure before chemical immersion 72 hours at 72ºF. Add 12 hours additional cure time for each 10ºF below 72ºF. Subtract 12 hours of cure time for each 10ºF above 72ºF. Force Cure with heat for best performance for 4 hours at 150ºF (66ºC), 12 hours at 100ºF ( 38ºC).

CLEAN UP: Clean tools immediately after use with M.E.K., Acetone, 98+% Isopropyl Alcohol 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. Consult the Product Safety Data Sheets (SDS) BEFORE USE!
