KELIGRIT™ INSTRUCTIONS
|
The following are Keligrit instructions for drilled holes, mixing, surface preparation, uses, installation,
shelf life, shipping, hot weather, cold weather and cautions. |
Drilled Holes |
|
Kelken recommends that all holes for anchors be made with air tools whenever possible.
Pneumatic drilling cleans the hole and prepares it for easy bonding. Sinker drills will make
a hole much faster than comparably priced electric tools.
Holes made with hollow bits will need only an air blowout FROM
THE BOTTOM UP using an air pipe.
|
Mixing |
- Keep material cool, store at 70°F
- Mix Keligrit™ and silica sand thoroughly for at least three to four minutes using jiffy mixer
- Add catalyst, then use the jiffy mixer in a rotary movement around perimeter of pail mixing for at least three to four minutes
- Make sure catalyst is thoroughly mixed top to bottom
- Do not disturb the anchor for 1 hour
NOTE: If Keligrout™ is used on jobsite, mix as one to one ratio with a clean silica sand.
|
Surface Preparation |
|
Electric drilled holes should be wire-brushed in addition to air blowouts so
that concrete dust can be cleared allowing for good bonding. If holes were
DIAMOND CORE DRILLED, KELKEN RECOMMENDS that the sides of the holes be
scored which will allow the resin to develop a keying action to the
concrete surface.
|
Uses |
|
Keligrit™ will anchor Kelianchors, direct track fixation fasteners,
dowels, rebar, rock anchors and mine roof bolts to concrete or
rock. Holes must be free of standing water and clear of all debris.
|
Installation |
|
Pour mixed resin into the bottom of clean air blown drilled holes. The holes may be damp, but should not have running or standing water present.*
The rods are pushed to the bottom of the holes and rotated to assure total
"wetting". They are left undisturbed until the exothermic gel occurs, which
happens within 40 minutes to 2 hours depending on the ambient
temperature at the time of installation.
After the material has cooled following the gel stage, it
will have 50 to 60% of its ultimate strength. Complete cure is
assured with 24 hours.
*Call for special advice if these conditions are unavoidable.
|
Shelf Life |
|
The shelf life of Keligrit™ is 6 months from date (our lot number) which is
stamped on every can.
Store Keligrit™ at 70°F out of direct sunlight. Storage temperatures should never exceed 85°F
|
Shipping |
|
When shipping Keligrit™ always use D.O.T. # Adhesive UN1133.
|
Hot Weather |
- Keep Keligrit™ cool until immediately before using. An insulated
cooler (and a little ice on really hot days) will do a good job.
- Keep containers of Keligrit™ out of direct sunlight.
|
Cold Weather |
- Always use two containers of catalyst when temperature is below 45°F
- Keep Kelianchor, rebar or coilrod and Keligrit™ warm (70°F)
until immediately before using.
- A 100 watt bulb enclosed in a lockup box or insulated cooler works well
at the job site. Material can also be warmed under a compressor engine's cover or in a truck cab.
|
Caution |
Solvents for Keligrit™ are highly flammable and volatile.
DO NOT SMOKE OR USE NEAR OPEN FLAME OR SPARKS.
For professional use only!
