4 SC PRO Introduction The SC PRO Anchor System consists of self contained two-part glass capsules and matching chisel pointed anchor rod which is installed using a rotary haer drill and rod adapters. For installation in diamond core drilled holes, contact Powers Fasteners for details. The SC PRO adhesive is a vinyl ester based resin material packaged in single use glass capsules designed for use in the installation of 8 through 24 threaded rod in solid concrete and masonry materials. It can also be used for reinforcing bars. During installation, the SC PRO System bonds the threaded rod to the base material so no expansion forces are exerted against the walls of the hole in the base material. This makes it ideal for use in anchoring to solid base materials ranging from soft coon brick to hard marble or granite. Unlike expansion anchors, the anchor can be set close to the edge of the base material. Product description SC PRO capsule The SC PRO adhesive is packaged in single use glass capsules which have premeasured components. A separate capsule is used for each size of 8 through 24 threaded anchor rod. An outer capsule contains epoxy acrylate resin (vinyl ester) in which quartz aggregate is suspended. The inner capsule contains a benzol peroxide hardening agent. When the components are combined, they form an adhesive mortar which mechanically bonds the anchor rod to solid base material. This type of system must be used with a chisel pointed anchor rod which is spun into it using a rotary haer drill. SC PRO chisel pointed anchor rod The SC PRO System is designed to be used with chisel STM TM pointed anchor rods. The threaded rod or reinforcing bar used must have a chisel point to mix the components contained in the capsule during installation.

6 SC PRO recoended curing times The setting times for the SC PRO adhesive mortar are listed below. The setting time is the minimum time required for the mortar to reach its published physical properties and is listed for the base material temperature, not ambient air temperature. For example, when making installations inside a building in exterior walls during the winter, the temperature of the hole may be different than the interior temperature and should be measured to determine the setting time required. In order to insure proper mixing, the capsule contents should be conditioned to 15 C prior to use. BASE MATERIAL TEMP. C SETTING TIME hours 20 and over 20 minutes 10 to minutes 0 to to to *Cure time should be doubled for wet concrete. Percent of Load Temperature (C) Effect of elevated temperature In-Service Temperature Allowable tension and shear load bond strength reduction based on in-service temperature for the SC PRO capsule adhesive. Installation procedure Drill a hole using the required carbide tipped bit to the embedment depth required. Use rotary haer drill only. For installation in diamond core drilled holes contact Powers Fasteners for details. Blow the hole clean with compressed air, brush the hole, and blow it clean again. Holes may be dry or damp, but should be free of standing water or frost. Insert the capsule into the hole. Either end of the capsule may be inserted first. Select the drive unit, insert it into a rotary haer drill and engage the coupling to be used. Insert the chisel point of the rod into the hole to break the glass capsule. Spin it into the capsule at a speed of 250 to 500 RPM until it is fully embedded. Once the rod is fully embedded, turn the rotary haer drill off iediately. Allow the Capsule-Stud to cure for specified time before loading anchor. Do not disturb the rod once the material has begun to set. 6

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. 7

10 Special applications Installation of anchors under water SC PRO Anchor capsules can be used to install threaded anchor rod or reinforcing bars in submerged applications under water provided some installation and design criteria are followed. The anchor holes should be prepared following the standard instructions with the following exceptions. Special care should be taken to clean the anchor hole as a slurry of concrete paste tends to form on the walls of the anchor hole when drilling under water. Insert the proper size capsule into the anchor hole. Be sure the capsule is fully inserted to the bottom of the hole. Follow the standard installation instructions for spinning the anchor rod used into the capsule with an appropriate tool for submerged use. The setting time of the SC PRO adhesive in submerged applications depends upon the base material temperature. Laboratory tests and field experience have shown that a decrease of 15 to 20% in the characteristic ultimate tension load capacity can be expected for an adhesive anchor which is installed under water. The design professional should include this reduction in their calculations.
