LOCTITE® PC 5070 PRO

You will need water and a wire brush or pocket knife to perform the repair. Locate leak following standard leak detection procedures, then reduce line pressure to 60 psi (4 bar) or lower. Roughen pipe surface using wire brush and supplied sanding cloth to remove excess rust, dirt or loose scale. Remove any oils, greases, soaps or foreign materials from pipe surface using the included solvent cleaning wipe. For maximum adhesion, the prepared area should be 3 to 4 times the size of the damaged areas. FOR UNDER PRESSURE REPAIRS: Unroll the first 6" (15 cm) from roll of black rubber Pressure Sealing Tape and remove backings; set aside. For DEPRESSURIZED SYSTEMS the Pressure Sealing Tape is not needed.

EPOXY PUTTY APPLICATION

Remove the wrapping from the EA 3463 Epoxy Putty then simply mix and knead until it is uniform in color. Maximum mixing time is 3 minutes. Minimum mixing temperature is 10°C (50°C). Follow additional instructions below for your application then proceed to step 3. JOINT: Mold mixed LOCTITE® EA 3463 into 3 - 6 mm (1/8" - 1/4") rope and place around entire circumference of the joint, pressing firmly into place. The rope should not exceed the shoulder of female fitting. DEPRESSURIZED PINHOLE/CRACK: Press the mixed ball of LOCTITE® EA 3463 firmly into the hole or crack. UNDER PRESSURE PINHOLE/CRACK: Place small ball of mixed LOCTITE® EA 3463 just large enough to fill the void above pinhole. OPTIONAL: For difficult live leak repairs, apply Butyl Strip(s) in addition to LOCTITE® EA 3463. Remove adhesive backing from Butyl Strip(s) and apply in an overlapping manor around the entire circumference of the joint atop the putty. NOTE: For under pressure repairs proceed to Step 3. For depressurized repairs skip to step 4.

LIVE LEAK/UNDER PRESSURE SEALING

Press adhesive side of black rubber Pressure Sealing Tape onto pipe beside LOCTITE® EA 3463 putty, or Butyl Strip, and overwrap 2 layers of Pressure Sealing Tape onto itself in a clockwise direction, thus anchoring the Pressure Sealing Tape to the pipe. Continue wrapping Pressure Sealing Tape, stretching it to its maximum tension, working toward putty, thus pushing the putty into the defect. Wrap remainder of Pressure Sealing Tape DIRECTLY over the putty, forcing the putty into the defect. STOP! Test repair by following your leak detection procedure to ensure the leak is sealed and contained. If leak persists, remove Pressure Sealing Tape and putty then repeat steps 2 and 3.

WRAPPING THE REPAIR

Put on supplied gloves, open foil pouch and submerge roll of LOCTITE® Advanced Pipe Repair Outer Wrap in water for approximately 10 seconds to activate the resin. 8 layers of LOCTITE® Advanced Pipe Repair Outer Wrap are required and must extend 5 cm (2") beyond both sides of the primary sealant, covering the entire repair site. To achieve 8 layers, apply 4 clockwise passes using a 50% overlap. TIP: When applying to odd geometries, occasionally twist the LOCTITE® Advanced Pipe Repair Outer Wrap as it is applied to help it conform tightly to the pipe.

PROTECTING THE REPAIR

Apply 4 layers of clear plastic compression film over the entire composite repair. Using a perforating tool or wire brush, perforate all layers of compression film to allow the gas generated by the curing process to escape. Remove compression film after approximately 10 minutes. Once the LOCTITE® Advanced Pipe Repair Outer Wrap has reached its initial cure (30 min @ 24°C/75°F), if maximum durability is desired, protect with a LOCTITE® protective coating, such as LOCTITE® PC 7255 or LOCTITE® PC 7227.
