FX-3112 Highly Chemical Resistant Coating

DESCRIPTION:

FX-3112 Highly Chemical Resistant Coating is a solvent free, high functionality Novolac epoxy coating suitable for immersion and non-immersion service. Designed specifically as a Methanol resistant coating, FX-3112 is well suited for protection in a wide array of aggressive acids, alkalies and organic solvents. FX-3112 produces a tough, chemical resistant coating on ferrous and non-ferrous metals and concrete.

Where to Use:

Methanol Pumps
Tanks
Pipes
Aggressive Chemical Tank Linings and Secondary Containment Area
Industrial Floorings
Excellent where force cure is not available

SURFACE PREPARATIONS:

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 should be primed with FX-3112 as soon as possible.

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 coating should be abrasive blasted to clean concrete. Prime with FX-467.

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. Avoid entrapping air. Mix until uniform color.

APPLICATION:

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, 1/4" on concrete.

Plural Spray—Use .019 - .021 tip, 2,000 - 2,500 psi, heat to 120°F Base, 110°F Activator.

Airless Spray—Use .019 - .023 tip, 2,000 - 2,500 psi with in-line heater only (Caution: Short Pot Life)

Conventional Spray—Not Recommended

All spray equipment should employ traps to prevent water and oil from contaminating coating and screens to prevent particulate contamination. Never thin.

STORAGE:

Material: Keep between 55 - 95°F (13 - 35°C). Substrate: Keep between 45 - 105°F (7 - 40°C). The difference in temperature of the substrate and the coating should never exceed 10°F (5°C).

CURE TIME:

Brush or roller, recoat between 6 and 14 hours at 77°F (25°C). Spraying recoat between 3 and 14 hours. Full cure before immersion 7 days at 77°F. Force Cure: 12 hours at 150°F (66 °C); 6 hours at 250°F (121°C).

CLEAN-UP:

M.E.K. or similar

CAUTION:

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 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.
