Admix EA641

Properties
• Excellent adhesion to concrete and most construction materials.
• Excellent early and final mechanical strengths.
• Excellent chemical resistance.
• Impact and shock resistance.
• Color coded components to ensure proper mixing control.
• Good wetting properties, no primer or bonding agent is needed on dry substrate.
• Easy to apply.
• Low odor.
• Non-sagging and non-slumping material.
• Can be extended with quartz sand as a repair mortar.
• Will not corrode reinforcement.
• Suitable for use in vertical and overhead applications.

Application method & Surface preparation
The substrate must be sound and free of loose particles. Remove dust, laitance, oil, grease, curing compounds, waxes, disintegrated and other bond inhibiting materials from the surface. If necessary, surface can be prepared by blasting methods, grinding, or chipping.

Mixing
Mix each component separately. Add component “B” to Component “A” and mix them thoroughly using a low speed drill (max. 400 rpm) fitted to the suitable paddle for at least 3 minutes or until all striations have disappeared and a uniform color is obtained. For partial mixing, add 1 part of component “B” to 3 parts of component “A” by weight and mix them thoroughly. Mix only required quantity which can be used within the pot life. To produce an epoxy repair mortar, slowly add up to 1 part by loose volume of quartz sand (0.1~2.0 mm) to 2 parts of mixed ADMIX EA641 and mix until uniform consistency be achieved.

Application
Thoroughly mixed ADMIX EA641 should be applied in a thickness of minimum 2 mm on segment surface using a trowel, spatula or knife. It can be applied on both segment surfaces. Place and fix elements within given open time. Excess materials should be removed. The material will reach designed strengths after 7 days.

Material consumption
Approximately 1.6 kg/m² for 1 mm layer thickness.

Limitations
• Minimum layer thickness 0.5 mm
• Maximum layer thickness 5.0 mm
• Do not apply ADMIX EA641 at temperatures less than +5 ºC.
• Do not thin ADMIX EA641 by solvent. Solvent will prevent proper curing.
• Minimum age of concrete must be 21~28 days, depending upon curing and drying conditions.

Cleaning
Tools and equipment should be clean after each application job or before break time. Uncured material can be washed with approved solvent. Cured material can only be removed mechanically.

Storage / Shelf life
Store the product out of direct sunlight on pallet, and protect from extreme heat and rain fall. The shelf life for originally unopened package is 12 months from date of production.

Packaging
ADMIX EA641 is available in 4 and 12 kg sets.

Safety precautions
Product may cause skin irritation. Use personal safety devices such as gloves and goggles. If contacted with eyes or mucous membrane, wash immediately with plenty of water and seek medical attention.
