Complete HDPE Pipe Repair Guide

High Density Polyethene (HDPE)

High Density Polyethylene, a thermoplastic, is used for plastic bottles and plastic pipes,
tanks and containers. Polyethylene is the most commonly used polymer and comes in
various forms; HDPE, Low Density Polyethylene (LDPE or simply polyethylene) among
others. Like all other polymers, HDPE is difficult to glue. High Density Polyethylene,
however, is easily bonded to itself, to other polymers and/or to other substrates* with
our patented Polymer Bonding Process (patented).

The Bonding Poly Process Difference

Polymers are functional and cheap. Their utility is only increased when you can
combine via the Process a polymer like HDPE with other substrates. The Process has
enabled innovators to bond silicone rubber to polycarbonate, PTFE to steel, nylon to
aluminum, etc. New uses for HDPE will be developed by other entrepreneurs.

The Process bonds polymers, including HDPE.

The primary advantages of a bond, is its durability over a glue joint and that it provides
a complete and full seal. You can expect your repair to be leak free. When you glue two
items together, there is a layer of glue connecting the two substrates. With a molecular
bond, there is a sharing of electrons. Age, weather, normal wear and tear will not affect
a bond the way that those conditions will impact a glue joint. This permanent bond is also
impervious to gas, oil, hazardous waste and most chemicals. It is also food safe, making it the
ideal repair choice for drinking water pipelines.

So, repair your HDPE pipe with the Process. Bond HDPE to any substrate. If you are
an inventor, explore with confidence all the options that are now available to you with the
process. It is the permanent, full seal, high pressure, affordable, zero leak, food safe, HDPE pipe repair method of choice.

HDPE Pipe Repair Steps:

1) Rough the HDPE around the problem area with sandpaper.
2) Drill a hole at each end of the crack so that internal pressure will not cause the crack to expand.
3) Clean with any cleaner that will not leave a residue. Dry thoroughly. Apply Poly Prep adhesion promoter on the area of pipe to be bonded.
4) Spray the Activator/Accelerator (AA) on the prepped area. Let the AA dry.
5) Apply the SI Blue to the Tech-Patch with continuous circles EXCEPT on diagonal corners. Paying special attention to having the adhesive reach the edges.
6) Grab the diagonal corners on the Tech-Patch, apply tension.
7) Press the Tech-Patch to the problem area on the HDPE.
8) Use the glue squeegee to apply firm pressure to the Tech-Patch from the center out.
9) Bond the diagonal edges to the HDPE with the SI Blue Spray with AA.
10) Apply a bead of the SI Blue to the perimeter of the Tech-Patch. Spray with AA.
11) Visually inspect.
