Epocon may also be used for bonding and repairing concrete, wood restoration work, dowel and anchor bolt grouting adhesive and as a gap-filling adhesive/sealant. Repairing cracked concrete, setting ceramic tiles, bonding decorative concrete blocks, and patching spalled concrete. Positive surface build-up on vertical walls without sagging is attainable. Check with local supplier for details.

 

 

 

TECHNICAL DATA
MIXING RATIO:  2 Parts “A” to 1 Part “B” by volume.  Mix until color streaks disappear and a uniform gray color is obtained.  Due to paste like consistency, it is recommended to mix mechanically with a slow speed drill.

COLOR: Part “A” – off white,  Part “B” – gray

MIXED PARTS: Concrete gray

CONSISTENCY: Very heavy paste, to easily allow surface build-up on vertical surfaces.

POT LIFE: Working life – 40 to 45 minutes @ 77o F.  Longer for lower temperatures.

CURE TIME: 24 hours @ 77o F

SHELF LIFE: Minimum one year in separate unopened containers.

INSTALLATION
Application by trowel or putty.  Proper surface preparation such as sand-blasting, grinding, wire brushing or other suitable means as required is essential for proper adhesive or caulking performance.  Surfaces to receive adhesive or caulking must be structurally sound, dry, clean, free of dirt, water, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing, curing and parting compounds, membrane materials, or any other contaminants which might prevent satisfactory bond and epoxy cure.  Thorough mixing of Epcon 850 using mechanical Jiffy mixer whenever possible, is essential for satisfactory performance.  Although it is of a paste consistency, Epocon 850 blends readily and is quite workable in its mixed state.  Always pay strict attention to ambient, and surface temperature of repair areas.  Selection of a Type “II” cold weather Epocon 850 may be dictated.

CLEAN UP
Use aromatic solvents such as Toluene, Xylene or MEK with uncured material only.
