DESCRIPTION AND RECOMMENDED USES: ARCOR™ S-30 is a solvent free, high functionality epoxy Novolac designed particularly as a protective coating for metals in immersion service. ARCOR™ S-30 produces a tough, chemical resistant, low friction coating that is ideally suited for aggressive water service(salt, brackish). The ARCOR™ S-30 multi functional chemistry produces a fine multipurpose coating suited for moderate acid and caustic service, and is excellent at elevated temperatures. Superior performance in petrochemical environments, crude oil, diesel fuel, gasoline. ARCOR™ S-30 can be applied up to 60 mils without slump.

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. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted surfaces to be primed with ARCOR™ S-30 Prime. Concrete surfaces : Not Recommended for hand or roller application. Apply by heated plural or airless spray only. Concrete surfaces should be degreased if oil and grease contamination is present. Degreased surface shall be high pres- sure 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. Mix by Volume 2 parts Base to 1 part Activator. Or by weight 100 grams base to 52 grams 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 .019-.021 tip, 3,000-3,500 PSI, Heat to 130ºF Base, 110ºF Activator.

Airless Spray use .019-.021 tip, 3,000-3,500 PSI(45:1). Recommended only with in-line heater at 120º to 135ºF.(Caution: Short Pot-Life)

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).

OVERCOAT / CURE TIME: By Brush or Roller re-coat between 6 and 8 hours at 72ºF (25ºC).

When spraying re-coat between 5 and 8 hours. Full cure before immersion 3 Days at 77ºF. Force Cure: 12 hours at 150ºF (66ºC);  6 hours at 250ºF (121ºC).

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.
