T308+ is a two-component epoxy adhesive anchoring system. The system includes injection adhesive in plastic cartridges mixing nozzles, dispensing tools and hole cleaning equipment. The T308+ is designed for bonding threaded rod and reinforcing bar into drilled holes in concrete base materials.
The T308+ epoxy adhesives is a smooth paste formulation with low odor that is solvent-free, V.O.C. compliant and does not contain mercaptans. The material conforms to ASTM C 881, Type I, II, IV & V, Grade 3, Class C (with the exception of gel time). T308+ has a two-year shelf life with when stored in a dry, dark environment with temperature ranging from 40ºF to 95ºF.- Tested in accordance with ICC-ES AC308 criteria
- Evaluated and qualified by an accredited independent testing laboratory for use in uncracked concrete
- Cartridge design allows for multiple uses using extra mixing nozzles
- Mixing nozzles proportion adhesives and provide simple delivery method into drilled holes

- Drill hole into concrete using a rotary-percussion power drill and a carbide-tipped SDS or SDS-Plus type bit. Drill bit size should be 1/16" larger than the anchor rod for sizes up to 1/2" diameter; and 1/8" larger for anchor rods 5/8" through 7/8" diameter.
- Blow out hole using oil-free compressed air at a minimum of 70 psi with a nozzle. While blowing air, insert the nozzle into the hole until in contact with the bottom, and then withdraw; whereby the blowing procedure takes at least one full second.
- Insert an appropriate size nylon cleaning brush into the hole with a thrusting, twisting motion. Once the brush is in contact with the bottom of the hole, turn the brush three full revolutions. Then quickly withdraw the brush with a vigorous, twisting pull.
- Repeat brushing of hole as per Step 3 above.
- Repeat blow out of hole with air as per Step 2 above.
- Screw the supplied mixing nozzle on to the cartridge, insert cartridge into an approved dispensing tool supplied by Powers Fasteners, and dispense epoxy on a disposable surface until a uniform color is achieved. Then insert the cartridge nozzle into the borehole until in contact with the bottom. Then, dispense the adhesive while slowly withdrawing the nozzle until borehole is approximately two-thirds full, and then withdraw the nozzle.
Slowly insert a clean and oil-free rod into the adhesive in the hole with a counter-thread, turning motion until it contacts the bottom of the hole.
Immediately adjust the alignment of the anchor rod in the hole. Check that the anchor remains fully in the hole. An air bubble in the hole could cause the anchor rod to rise after insertion. If this occurs immediately turn the anchor with the downward pressure to work the air out. Do not disturb , torque or load the anchorage until the adhesives is fully cured.
