1 184 Power-Bond PUMP & DUAL CARTRIDGE BASE MATERIAL Solid Concrete, Block, Brick, Stone or Masonry SIZE RANGE 3" to Anchor Rod. No. 3 to No. 8 Reinforcing Bar Upon completion of mixing, pull the plunger handle out in the direction shown to extend the built-in nozzle. Be sure the plunger is completely extended. Unscrew the T-shaped handle portion of the plunger. The nozzle has an O.D. of.42 inches. Insert into a caulking gun and dispense material. For use as an adhesive anchoring system, follow Powers Injection Adhesive Installation Procedures. ANCHOR MATERIAL Two Component Epoxy PRODUCT DESCRIPTION The Power-Bond Epoxy Pump System consists of a self contained pump style cartridge in which the adhesive components are mixed. A standard manually operated caulking tool can be used in the installation of threaded rod, bolt or reinforcing bar in solid concrete. The Power-Bond Epoxy Pump System is supplied in 1 fluid ounce cartridges to meet the needs of most smaller applications. For easy pumping, a lower viscosity epoxy material is used as opposed to the paste style epoxies used in side by side cartridge systems. Once the material in the cartridge is mixed, it must be used within the specified gel time. The best installation method is to prepare the anchor holes in advance and have the anchor rods ready prior to mixing the components. It is not recommended for use with screen tubes in hollow base materials. MIXING GUIDELINES Prior to mixing, lightly turn the T-shaped handle clockwise until tightened to make sure it doesn t pop out when initially pulled. Pull plunger handle in the direction shown until the white barrier rings reach the top of the cartridge. Pull hard to ensure divider has been opened and pulled to the top of the cartridge. While holding the bottom of the cartridge, mix the epoxy by pumping the plunger handle at least 35 full strokes. Be sure to use full strokes to ensure the material is fully mixed. Do not use material that is not mixed properly. For ease of mixing and dispensing, condition to 7 F minimum. Do not use in base material temperatures below 4 F. PRODUCT DESCRIPTION Power-Bond is also available in 1:1 ratio dual cartridge system. In addition to our successful 1 fluid ounce pump style cartridge, it is also packaged in specially designed, 15 fluid ounce dual cartridges made from an engineered plastic which is dispensed using either a manual or pneumatically operated injection tool. POWER-BOND MATERIAL PROPERTIES The Power-Bond adhesive is a low viscosity amine based epoxy for use in either a pump style cartridge or 1:1 dual cartridge. The performance criteria for use as an anchoring system for threaded rods and reinforcing bars are described in the sections that follow. Shelf Life 1 year in original cartridge Storage Conditions Store dry at 4 to 9 F. Color Uniform Gray Useable Volume (Pump): 1 fluid ounces 18 cubic inches Useable Volume (Dual Cartridge): 15 fluid ounces 27 cubic inches Cartridge Weight (Pump): 1 pound Cartridge Weight (Dual Cartridge): 1-1 pound

2 185 EFFECT OF ELEVATED TEMPERATURE As with all adhesive anchors, the bond strength of the Power-Bond adhesive mortar is affected by elevated temperatures in the base material. As the temperature of the base material increases, the bond strength of the anchor will decrease. Typical performance of the Power-Bond epoxy at elevated base material temperatures is shown below. The values are based on maintaining the concrete test samples used at a given temperature for a minimum of 24 hours before applying a test load. Percent of Load POWER-BOND RESIN RESISTANCE TO S Temperature ( F.) The resistance of the cured Power-Bond epoxy to various chemicals was determined according to ASTM Specification C 581 by laying molded samples of the resin in the respective chemical agents. The samples were subjected to a bending strength test before and after a 12 month exposure to the chemicals. The adhesive was rated as resistant if there was no visible deterioration and less than 25% reduction in bending strength. This exposure is extreme. Under normal installation conditions, the adhesive is exposed to the chemical agents only at the surface of the concrete around the top of the anchor hole.

4 187 INSTALLATION GUIDELINES - SOLID BASE MATERIALS Drill a hole to the size and embedment required. The tolerances of the drill bit used should meet the requirements of ANSI Standard B Starting from the bottom or back of the anchor hole, blow clean with compressed air, brush the hole with a nylon brush, and blow it clean again. Vacuuming only is not sufficient. Blow out bulbs generally do not provide enough dust removal for most drilled anchor holes. Holes should be clean and sound. They may be dry or damp, but should be free of standing water or frost. If using reinforcing bar, be sure the bar will fit into the drilled hole. If a larger hole is required, the diameter should be as close as possible to the diameter of the reinforcing bar. adhesive starting from the bottom or back of the anchor hole. Slowly withdraw the static mixing nozzle as the hole fills to avoid creating air pockets. Push the threaded rod or reinforcing bar into the anchor hole while turning slightly to ensure positive distribution of the adhesive. Be sure the rod is fully seated at the bottom of the hole and that some adhesive has flowed from the top of the hole. The threaded rod or reinforcing bar used should be free of dirt, grease, oil, or other foreign material. Allow the adhesive to cure for the specified time prior to applying any load. Do not disturb or load the anchor until it is fully cured. Prior to dispensing into anchor hole, visually inspect that adhesive components are uniformly mixed. Fill the hole approximately half way with Prior to use, read product label, Material Safety Data Sheet and injection tool instructions.

6 189 DESIGN CRITERIA BASE MATERIAL THICKNESS The minimum recommended thickness of solid concrete or masonry base material, BMT, when using an adhesive anchor is 125% of the embedment to be used. For example, when installing an anchor to a depth of 4", the base material should be at least 5" thick. Conversely, the maximum embedment should be 8% of the base material thickness. If a concrete slab is thick, an 8" depth would be the maximum recommended anchor embedment. This does not apply to products designed for installation in hollow base materials. S S E D = Anchor Size S = Spacing E = Edge Distance BMT = Base Material Thickness COMBINED LOADING For anchors loaded in both shear and tension, the combination of loads should be proportioned as follows based on the Uniform Building Code: T 5 /3 () S VS T A () V A Where: Ts = Applied Service Tension Load TA = Allowable Tension Load Vs = Applied Service Shear Load VA = Allowable Shear Load Dependent upon the election to conduct certain optional independent test procedures, many ICBO evaluated products are currently analyzed more conservatively with the following proportion. TS TA /3 + 1 T () S VS T A () V A + 1 TS VS () () TA VA + 1 (straight line) VS VA E D 5 /3 TS VS () () TA VA 5 /3 S + 1 (parabolic) BMT S ADHESIVE ANCHOR SPACING AND EDGE DISTANCE Adhesive type anchors can be installed closer to the edge of a concrete slab than mechanical anchors with no cracking of the base material. The published ultimate and allowable working loads are based on testing conducted at the spacing and edge distance required to obtain maximum load and should be reduced to account for decreased spacing and edge distance. The reduction load factors listed are cumulative. For example, the allowable working load for an anchor which is installed at a spacing and an edge distance less than that required for maximum load capacity would be multiplied by the appropriate factor from both the spacing and edge distance tables. The factors are normally applied to the allowable working load of the adhesive resin and then compared to the allowable strengths of the steel anchor rods used. See the Design Example featured earlier in this manual. SPACING BETWEEN ADHESIVE ANCHORS The following table lists the load reduction factor, Rs, for each anchor diameter, D, based on the center to center anchor spacing. To obtain the maximum working load in tension or shear, a spacing of 8 anchor diameters (8D) or greater should be used. The minimum recommended anchor spacing is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 3%. Anchor spacing closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.

7 19 EDGE DISTANCE FOR ADHESIVE ANCHORS EDGE DISTANCE - TENSION For adhesive anchors loaded in tension, the following table lists the load reduction factor, Re, for each anchor diameter, D, based on the anchor center to edge distance. To obtain the maximum tension load, an edge distance of 6 anchor diameters (6D) and greater should be used. The minimum recommended edge distance is 4 anchor diameters (4D) at which point the allowable working load for the adhesive resin should be reduced by 4%. Edge distances closer or less than 4 diameters (4D) need to be field tested. Actual base material conditions will determine any applicable reduction factor.
