ARCOR Spraythane FL
Updated May 2020



DESCRIPTION AND RECOMMENDED USES: ARCOR™ SPRAYTHANE FL is a high elongation, elastomeric, hybridized epoxy/urethane. It is designed as a high resilience, high tear resistant, high impact resistant coating that is ideal to combat cavitation and abrasion, and it is completely compatible with epoxy coatings. The urethane aspect delivers a tough, flexible resilience while the epoxy aspect provides improved water and chemical resistance and shelf stability. ARCOR™ SPRAYTHANE’s FL epoxy reactivity eliminates the moisture sensitivity and toxicity associated with traditional urethanes.

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 primed with ARCOR™ S-30 Prime. 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 and oils and surface laitance. Existing coatings should be abrasive blasted to clean concrete. Prime with ARCOR™ EE-70, EE-79 or ARCOR™ EE-10.

MIXING: Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade, thoroughly scrape sides and bot- tom. Mix by volume 2 part Base to 1 part activator, by weight 100 gm Base to 52.2 gm activator.

THINNING: Never thin.

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

By brush use medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating. Trim or tape to <1” nap.

Roller use good quality 1/8” nap.

Plural Spray use .023-.028 tip, 3,000-3,500 PSI, Heat to 130ºF Base, 110ºF Activator. Airless Spray use : Not Recommended

Conventional Spray: Not Recommended

APPLICATION TEMPERATURE: Material: Keep between 55 to 95ºF (13 to 35ºC). Substrate : Keep between 45 to 105ºF (7 to 40ºC). The difference in temperature of the substrate and the coating should never exceed 10ºF (5ºC). Substrate shall be a minimum of 5ºF (3ºC) above dew point.

OVERCOAT / CURE TIME: Re-coat between 6 and 12 hours at 77ºF (25ºC).

Full cure before immersion 72 hours at 77ºF. Force Cure: 12 hours at 120ºF (49ºC).

CLEAN UP: 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.
