 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 primed immediately to prevent oxidation of surface.

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.

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

THINNING:

Never thin.

APPLICATION:

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 1/8” nap.

Plural Spray: .031-.039 tip, 2,500-3,500 PSI, Heat to 180ºF Base, 140ºF 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 mix- ing. 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 1-8 hours at 77ºF(25ºC). 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 1-4 hours at 77ºF. Full cure before immersion 72 hours at 77ºF. Add 1 1/2 hours additional cure time for each 10ºF below 77ºF. Force Cure with heat for best performance for 1 1/2 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.
