KeliGrit

KeliGrit is a high strength, non-shrink polyester resin anchoring material. The material is particularly useful when anchoring in large diameter holes and sets rapidly in inclement weather. KeliGrit is highly cost effective. KeliGrit is easily mixed with a drill or jiffy mixer. Catalyst provided will cause exothermic get (set) in 40 min. at 70°F. KeliGrit May be used in freezing conditions down to 10°F by keeping resin warm (70°) immediately prior to use.

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.

1-1/2 gallons of resin, properly pre-portioned catalyst, and 1-1/2 gallons of silica sand is packaged into a 5 gallon pail. When mixed together it produces 2.4 gallons of material.

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.

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.

Mixing

If Keligrout™ is used on jobsite, mix as one to one ratio with a clean silica sand.

1. Keep material cool, store at 70°F
2. Mix KeliGrit and silica sand thoroughly for at least three to four minutes using jiffy mixer
3. Add catalyst, then use the jiffy mixer in a rotary movement around perimeter of pail mixing for at least three to four minutes
4. Make sure catalyst is thoroughly mixed top to bottom

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

1. Always use two containers of catalyst when temperature is below 45°F
2. Keep KeliAnchor, rebar or coilrod and KeliGrit warm (70°F) until immediately before using.
3. 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!

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. Call Kelken at 732-416-6730 for special advice if these conditions are unavoidable.

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.

Mix KeliGrit and silica sand together.

Thoroughly mix with jiffy mixer for at least three to four minutes.

Add catalyst, then use the jiffy mixer in a rotary movement around the perimeter of pail mixing for at least three to four minutes. NOTE: Make sure catalyst is thoroughly mixed top to bottom.

Pour or ladle the resin mixture into the bottom of the hole. To determine the amount of resin required, see table below. Place anchor and rotate to assure full "wetting" of surfaces. Do not disturb the anchor for 1 hour.
