 Fast Dispensing, Fast Curing Acrylic Adhesive
The acrylic resin and hardening agent are completely mixed as they are simultaneously dispensed from the dual cartridge through a static mixing nozzle, directly into the anchor hole. A7 can be used with threaded rod or rebar.

INSTALLATION STEPS
epcon_a7prod2e.jpg (4182 bytes) 1. Drill 1/16" oversize diameter holes for 1/4"–1/2" diameter threaded rods and #3 rebar. Drill 1/8" oversize diameter holes for 5/8"–1-1/4" diameter threaded rods, #4 rebar, grout filled blocks and brick pinning. Clean out hole from bottom with forced air. Complete hole preparation with brush and repeat cleaning with forced air (leave no dust or slurry).
epcon_a7prod2f.jpg (3349 bytes) 2. When starting new cartridge or new nozzle, dispense and discard enough adhesive until uniform grey color is achieved. Insert the nozzle into the bottom of the hole and fill to 1/2 the hole depth.
epcon_a7prod2g.jpg (3168 bytes) 3. Insert rod slowly by hand into the bottom of the hole with a slow twisting motion. This insures adhesive fills voids and crevices and uniformly coats the anchor rod.
epcon_a7prod2h.jpg (3737 bytes) 4.  See table for working times and curring times. After the suggested cure time is met, install and tighten fixture into place.

1 Allowable working loads for the single installations under static loading should not exceed 25% capacity or the allowable load of the anchor rod.
2 Ultimate load values in 2000 and 4000 psi stone aggregate concrete. Ultimate loads are indicated for the embedment shown in the Embedment in concrete column. Performance values are based on the use of high strength threaded rod (ASTM A193 Gr. B7). The use of lower strength rods will result in lower ultimate tension and shear loads.
3 Linear interpolation may be used for intermediate spacing and edge distances.

1 Allowable working loads for the single installations under static loading should not exceed 25% capacity or the allowable load of the anchor rod.
2 Ultimate load values in 2000 and 4000 psi stone aggregate concrete. Ultimate loads are indicated for the embedment shown in the Embedment in Concrete column. Performance values are based on the use of minimum Grade 60 reinforcing bar. The use of lower strength rods will result in lower ultimate tension loads.
3 SHEAR DATA: Provided the distance from the rebar to the edge of the concrete member exceeds 1.25 times the embedment depth of the rebar, calculate the ultimate shear load for the rebar anchorage as 60% of the ultimate tensile strength of the rebar.

Combined Tension and Shear Loading — for Epcon A7 Adhesive Anchors

Allowable loads for anchors under tension and shear loading at the same time (combined loading) will be lower than the allowable loads for anchors subjected to 100% tension or shear. Use the following equation to evaluate anchors in combined loading conditions:

epcon_a7selec5a.jpg (2017 bytes) Na = Applied Service Tension Load
Ns = Allowable Tension Load		 Va = Applied Service Shear Load
Vs = Allowable Shear Load
