FX-771

DESCRIPTION:

FX-771 LV Hydro-Ester® High Modulus is a two component, 100% solids, moisture insensitive epoxy resin system, mixed at a 2:1 ratio, with a viscosity of light-weight oil. FX-771 LV exceeds the requirements of ASTM C-881-02, Types I, II, Grade 1, Class "B" and "C".

ADVANTAGES:

High strengths.
Low viscosity permits easy flow crack grouting by gravity feed or pressure injection.
May be injected below water.
May be used in temperatures as low as 40°F (4°C).

WHERE TO USE:

Use neat for grouting damp and dry cracks or as a penetrating sealer on concrete.

Modulus of Elasticity (with 4 parts FX-700)	2.2 X 10⁶
Shelf Life	2 years

SURFACE PREPARATION:

Remove dust, laitance, grease and curing compounds from concrete surface by sandblasting or wire brushing. Cracks may be dry, damp, or wet.

MIXING:

Material should range between 65°F (18°C) and 75°F (24°C) to facilitate ease of mixing. Stir each component lightly prior to proportioning. Mix 2 parts Component "A" with 1 part Component "B". Mix thoroughly for 2-3 minutes with FX-Mixing Paddle and low speed drill until color is uniform. Mix with 3 parts FX-700 Epoxy Extender to grout base plates, set anchor bolts, or to fill the annular void in the FX-70® Inert Corrosion-Free System for pile protection and restoration. Mix with 4 parts FX-700 for a self-leveling grout. Mix with up to 5 parts of FX-700 for a patching mortar. When mixed with FX-700, color of mixed material is gray in color.

APPLICATION:

Automatic Pressure Injection—Use FX Automatic Pressure Injection Machine as shown in FN-101.

Manual Pressure Injection—Place one-way polyethylene valves every 12" to 36" along length of crack. Seal surface of crack to be grouted with FX-763 Trowel Grade. Pump FX-771 LV into lowest one-way valve. When epoxy reaches next highest valve, move up and repeat procedure. Pull valves after cure.

Penetrating Sealer—Apply mixed material with rubber squeegee or roller. Allow time to penetrate. Squeegee off excess while still liquid.

Patching—Apply neat FX-771 LV to prime clean sound substrate. Mix blended epoxy with FX-700 or FX-701 Filler and trowel in place.

Anchor Bolt Grouting—Diameter of hole should be minimum of 1/2" larger than that of bolt.

YIELD:

One gallon of mixed FX-771 LV will yield approximately:

750 cu. in. when mixed w/3 gallons FX-700—very pourable
925 cu. in. when mixed w/4 gallons FX-700—self-leveling
1100 cu. in. when mixed w/5 gallons FX-700—masonry mortar

LIMITATIONS:

Do not thin FX-771 LV solvents will prevent proper cure. Do not use for bonding new to plastic concrete, use FX-752. Substrate temperature and ambient temperature must not be below 40°F (4°C). Exposure to elevated temperatures for prolonged periods is not recommended.

Epoxy resin (A Component) may crystallize. Heating material to 120°F and stirring will reconstitute material to original condition. Allow to cool before using.

CAUTION:

WARNING! "A" Component contains epoxy resin. DANGER! "B" Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. use with good ventilation, particularly if material is heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves and/or barrier creams. Keep container closed when not in use. Wash thoroughly after handling.

FIRST AID:

In case of skin contact, immediately wash with soap and water. in case of eye contact, flush eyes with copious amounts of water for at least fifteen (15) minutes. Remove contaminated clothing shoes. If irritation persists, seek medical attention. Wash clothing before reuse.
