FX-777 Epoxy Saturant

DESCRIPTION:

FX-777 is a two-component, moisture-tolerant, high strength, high modulus epoxy resin. FX-777 is used as a binder for structural composites. It is easily applied by brush or roller and does not sag or run when applied. It can be used with Carbon, Fiber Glass or Steel reinforcements.

ADVANTAGES:

Flame Retardant
Thixotropic
Easy to mix - 3A:1B by volume
Tolerant of moisture before, during and after cure.
High strength, high modulus adhesive.
Excellent adhesion to concrete, masonry, metals, wood and most structural materials
Fully compatible and developed specifically for the FX Carbon Wrap System.

SURFACE PREPARATION:

Substrate must be clean, sound, and free of surface moisture. Remove dust, laitance, grease, oils, curing compounds, waxes, impregnations, foreign particles, coatings and disintegrated materials by mechanical means, i.e. sandblasting. For best results, substrate should be dry. However a saturated surface dry condition is acceptable.

MIXING:

Mix entire unit, do not batch. Pour contents of part B into part A. Mix thoroughly for 3 minutes on low using a paddle style mixer or low speed (400-600 rpm) drill until uniformly blended. Scrape sides and bottom to ensure complete mixing. Avoid entrapping air. Apply immediately after mixing.

APPLICATION:

FX-777 must be conditioned to 65-75°F (18-24°C) before use. Apply mixed FX-777 epoxy to a properly prepared substrate using a brush or roller. A medium 3/8" nap roller is preferred. Apply two coats of FX-777 for each layer of fabric applied, one as base coat and one as top coat, so that the reinforcement fabric is completely saturated by FX-777. Use grooved roller to eliminate air from composite.

LIMITATIONS:

Only apply FX-777 when ambient temperature is between 50°F and 110°F. Surfaces should be protected with a top coat within two days when exposed to direct sunlight. Otherwise, top coat should be applied within one week to insure proper adhesion of top coat to FX-777. Do not thin with solvents. Material is a vapor barrier after cure. Minimum age of concrete must be 21-28 days depending on curing and drying conditions.

CAUTION:

"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.
