ABOUT THE SYSTEM
Prime Resins "Quick Mix Cartridge System" was developed for ease of application with minimal waste of material. Unlike others, the "Quick Mix Cartridge System" is available with many different epoxy and polyurethane formulations providing a wide variety of applications.
A pneumatic or manual gun is available. The pneumatic gun can be operated by air compressor, air tank, or C02 tank. The pneumatic gun is recommended for all applications. The manual gun is ideal for surface sealing prior to injection, anchoring, doweling, spall repair and patching.
Cracks or joints should be 1/8" wide or larger for manual gun injection. The system can be used for large commercial and industrial projects or for smaller residential jobs.
USING THE CARTRIDGES
The gun should be set up for either a 2:1 (300 X 150 ML) or 1:1 (300 X 300 ML) ratio depending on the cartridge being used. Unscrew the retaining nut from the cartridge, remove small end caps, insert flow restrictor (low viscosity injection material only), slide retainer nut over static mixer and screw onto cartridge and tighten. Place cartridge into dispensing gun with the static mixer facing away from you.
Pneumatic Gun
Hook pneumatic gun to air source supplying air at 80-100 PSI. Use control regulator on back end of gun to adjust pressure from gun. Always start at the lowest pressure and slowly increase pressure as needed to achieve flow. Squeeze trigger until material is flowing out end of static mixer, some material will need to be discarded to ensure proper mixing. Discard until uniform color is achieved. Never attempt to reuse a static mixer. Reuse can result in material that is not properly mixed and the final product may not fully cure.
TEMPERATURE EFFECTS
All materials should be stored at a moderate recommended temperature (generally 60-700F) at least overnight prior to use. The viscosity and reaction time of epoxy and polyurethane's are sensitive to temperature. In cold weather, if materials are not pre-conditioned,t hey will become thicker and may become difficult to dispense. In hot weather they can become too thin or sag (gels) and may set up very fast.
INJECTION PORTS
Our ports can either be surface mounted (Surface Mount Ports) or can be inserted into pre-drilled holes (Socket Ports) if drilling, drill a 1/2" did hole approx. 1 " deep. Space ports 6-12" apart depending on crack width. Vacuum, brush, or wash the drilling dust out of holes. Improper cleaning of drill dust from holes will result in minimal penetration. When using the socket ports into drilled holes make sure that the end of the port does not touch the back of the hole.
EPOXY INJECTION
Surface seal:An epoxy gel is recommended for surface sealing prior to injection. Prime Resins PRIME GEL 2100 was designed specifically for this procedure. Prime Gel 2500 Quick Bond can be used to provide faster turnaround time. The surface of the crack should be cleaned either by mechanical or chemical means. The gel should be applied all along the crack in a 2" width and around all injection ports. Be sure to cover any area where the injection resin might escape. We recommend that you let Prime Gel 2100 set up overnight to allow it to fully cure before starting the injection process. If Prime Gel 2500 Quick Bond is used the crack can be injected in about 2 hours depending on temperature.
Injection: Always inject a vertical crack from the bottom up, horizontal cracks from left to right or right to left. Never skip around to random ports.
Surface Mount Ports: Put end of static mixer into port opening and apply a gentle push forward and begin injecting.
Socket Ports: If using crimp bands, place band on to port. (These will later be used to crimp port closed to contain material). Put end of static mixer into end of port or use the Prime Resins "Easy Connector" to attach the static mixer to port, begin injection. As the crack begins to fill up material may run out the next port. If this happens, crimp off or cap the port where the material is running out and continue to inject the first port. This will ensure that you are getting maximum penetration. At point of material refusal, crimp the metal sleeve with pliers or cap the port and move to the next port.
PRIME FLEX POLYURETHANE INJECTION
Surface seal: If surface is dry, an epoxy gel is recommended for surface sealing prior to injection. Prime Resins PRIME GEL 2100 was designed specifically for this procedure. Prime Gel 2500 Quick Bond can be used to provide faster turnaround time. The surface of the crack should be cleaned either by mechanical or chemical means. The gel should be applied all along the crack in a 2" width and around all injection ports. Be sure to cover any area where the injection resin might escape. If surface is wet or crack is seeping/leaking water, use Prime Plug 10 Hydraulic Cement, and apply same as epoxy gel outlined above. Allow Prime Plug 10 to set for 30 minutes before injecting.
Injection: Before injection, fill empty cylinder with clean water, and allow enough room to install tail plug. Water is needed to activate the polyurethane resin. Install large tail plug. Remove retainer nut and small caps. Insert flow restrictor and static mixer. Attach and tighten retainer nut. Begin injection. If using Socket Ports ask about our "Easy Connector" to connect the static mixer to the port.
ANCHORING
Set up gun to proper ratio. Drill proper size hole for anchor or dowel. Clean the hole with a nylon brush and blow it out with oil free dry compressed air. Install cartridge into gun and dispense material until a uniform color is achieved. Place static mixer into hole and dispense epoxy. Back mixer out of hole as you dispense. Remember that the bar will displace 40-80% of the epoxy. Before material begins to set up using a twisting motion insert bar all the way into hole.
The above instructions are only general guidelines. Exact procedure should be determined by the engineer, architect, or contractor. Prime Resins is not responsible for material that is improperly installed.
