52.1 Introduction
The Power-Fast Epoxy Injection Gel is a two component structural
epoxy which is available in two dispensing systems. For small to
medium size jobs, it is packaged in specially designed cartridges made
from an engineered plastic which are used with either a manual or
pneumatically operated injection tool. It is also packaged in reinforced
foil pack sausages which are dispensed from specially designed high
pressure manual or pneumatic injection tools. The epoxy used is an
odorless, premium, high strength epoxy which has a proven track record.
Power-Fast Epoxy Injection Gel is designed for use in anchoring
threaded rod, bolts, reinforcing bars, and smooth dowels into concrete
and other solid base materials. The system can also be used to anchor
into hollow masonry materials using threaded rod and screen tubes. In
addition to anchoring applications, Power-Fast Epoxy Injection Gel can
be used for bonding steel and cured concrete to cured concrete. It can
also be used for pick proofing applications, for surface sealing cracks,
and for placing injection ports. Details of all system components
including the Power-Fast  Epoxy Injection Gel, dispensing tools,
installation instructions, ultimate load capacities, and allowable
load capacities are described in this section.
52.2 Product Description
52.2.1 Power-Fast™ Cartridge
Power-Fast Epoxy Injection Gel is offered in two dispensing systems
to meet the installation requirements for most applications. The
cartridge system is suitable for small to medium jobs while the foil
pack version is preferred for larger jobs where faster dispensing of
material in larger volumes is required. Power-Fast Epoxy Injection
Gel is available in either fast and slow setting versions to provide
the installer with a choice of gel and curing times. For example, in
warmer weather, the slower setting version is normally used as it
allows the installer time to properly fill anchor holes prior to the
point at which the material begins to gel or solidify.
The design of the Power-Fast cartridge eliminates the leakage and
dispensing problems often found on other products. Supplied in 10, 15
and 24 fluid ounce capacities, each cartridge is manufactured in a side
by side configuration using two parallel tubes. One tube contains the
Component A - Base Resin while the other tube contains the
Component B -Hardener.

The tubes are separated by an air space to keep the components out
of contact until they are ready to be dispensed.
Each cartridge is formed from an engineered plastic using a special
high tolerance molding process. At the front end of each cartridge is a
reinforced retention guide and a threaded manifold. To prevent leakage
of the cartridge during storage, a sealing plug is inserted in the ports of
the manifold, followed by a molded cap which is threaded on. A set of
plastic pushers is inserted into the rear of each tube to pressurize the
epoxy during dispensing. The pushers are reinforced and contain an "0"
ring to prevent leakage during storage and dispensing. This provides
the user with a cartridge which is easy to dispense, yet durable.
52.2.2 Power-Fast Cartridge System Dispensing Tools
Both sizes of Power-Fast cartridge can be dispensed from manually or
pneumatically operated injection tools. Each tool has a dual piston
design which applies even, consistent pressure to the cartridge to
insure proper mixing, eliminating the possibility of measuring errors.

52.2.3 Power-Fast Sausage
In the sausage system, the Power-Fast™ Epoxy Injection Gel is
packaged in individual mylar reinforced foil sausages which contain 10
fluid ounces of Component A - Base Resin and Component B - Hardener.
The components are mixed in a 1 to 1 ratio using either a manual or
pneumatic tool system. The total amount of mixed epoxy available
for dispensing is 20 fluid ounces.

Each foil pack is labeled and color coded for easy identification of the
components. The Component A - Base Resin foil pack is white, the
Component B -Fast Set Hardener foil pack is red, and the Component
B - Slow Set Hardener foil pack is blue.
52.2.4 Power-Fast Sausage System Dispensing Tools
The Power-Fast sausages can be dispensed from specially designed
manual or pneumatic injection tools. Each tool is equipped with
aluminum guide cylinders which house the foil sausages. Simply
insert the Component A - Base Resin into the cylinder marked A and
either the Component B - Fast Set Hardener or the Component B -
Slow Set Hardener into the cylinder marked B. The tools are supplied
with a reusable manifold assembly which automatically opens the
foil sausages and delivers the components to the mixing nozzle. With
the foil packs housed in dual cylinders, maximum dispensing pressure
can be applied for fast injection of the epoxy into anchoring holes
because the aluminum cylinders can withstand a greater pressure
than the plastic cartridges, This makes the sausage systern the ideal
choice for larger jobs. The dual cylinder design applies even,
consistent pressure to the sausages to insure proper mixing,
eliminating the possibility of measuring errors.

52.2.5 Power-Fast Mixing Nozzles
To insure complete and proper mixing of the epoxy components, the
Power-Fast Systems use a static mixing nozzle. This reduces the
possibility of mixing errors which are common with hand mixed
materials. The nozzles have been designed with a unique tapered
extension tip to allow one nozzle to be used to inject epoxy into
most anchor hole sizes. Each nozzle contains a series of stationary
components called mixing elements. The elements are motionless
and remain in a fixed or static position as the epoxy components are
pumped through the nozzle.
As the components are pumped through the nozzle, they are
progressively divided and recombined by the stationary mixing
elements to insure precise automatic mixing of the components. To
ensure proper mixing, Power-Fast nozzles should be used.

Detailed information on the injection tools, mixing nozzles, and
accessories is listed in the Power-Fast Cartridge and Sausage
System selection guides.
