PE Fusion Acrylic Adhesive for Underground Utility Use
PE Fusion is high strength modified acrylic adhesive for the coupling of HDPE pipe to standard PVC couplings and other none-standard materials such as aluminum, steel, fiberglass, ABS, etc.
One 35 ml cartridge of PE fusion
can adhere 12-15 - 2" couplings.

Acrylic Adhesive Pull-Out Testing – 2” through 4” HDPE Pipe
PE Fusion Pull-Out Tests Results without PE Scraping Tool
PE Fusion was tested at Standard Testing Laboratories in Oklahoma City to determine the bonding strength for the joining of two end sections of High Density Polyethylene Pipe with a standard PVC coupling. Test equipment was a Tinius Olsen Super L Universal Testing Machine, (Tensile Tester). Test specimens varied from 2” to 4” diameter polyethylene pipe. Control values were established by using maximum rated pull-out strength for the standard mechanical coupling used extensively in the PE pipe industry. Test summaries are listed below. Pipe samples were prepared using a small scuff pad and were allowed to cure for 24 hours.
* IN ALL TESTS, THERE WERE NO ADHESIVE FAILURES, ALL FAILURES OCCURRED IN THE COUPLINGS.
** Prior to testing, sample #6 was subjected to impact testing with a 12# sledgehammer. Sample was struck twice, once on either side of the coupling.
PE FUSION ACRYLIC ADHESIVE
The PE Fusion System consists of an
application tool, plunger, two-part adhesive
cartridge and a static mixer.
Unlock the cartridge-retaining collar by lifting up on the collar's black latch at the top of the tool. Rotate the collar forward. Lift the metal tab at the rear of application tool and slide the plunger into the front of the tool with the ratchet teeth down. Slide the plunger all the way to the back of the tool before releasing the metal tab. Insert the cartridge in the wide slot in the collar. Push the collar back and press firmly on the front of the collar until it snaps into place. Remove the cap of the cartridge (save the cap to reseal).
Pump the handle gently to seat the plunger and extrude a small amount of adhesive from the front of the cartridge. This ensures a proper 10:1 ratio.
Place a new static mixer on the tip of the cartridge and twist until it locks into place. Pump the handle several times until the material begins to flow into the static mixer. As the material passes through the static mixer it will change to a uniform color. The material needs to be uniform in color (with no streaks) before using.
PE Fusion should be applied to surfaces that have been "roughed up" using a scuff sheet or pipe scraper. Rough up the exterior of the conduit and also the inside of the coupling.
Place the tip of the static mixer against the conduit. Apply PE Fusion completely around the conduit. Using the latex glove provided in kit, spread PE Fusion with your finger over the surface of the pipe and inside the coupling. Apply sufficient PE Fusion to ensure a small residual bead is rolled up at the top of the coupling after the conduit has been inserted into the coupling. Insert the conduit into the end of the coupling, turning the coupling as you push it onto the conduit. PE Fusion will set up in 3 to 5 minutes (depending on ambient temperature).
Upon completion, remove and discard the static mixer and replace the cap on the cartridge.
Note: The static mixer can be used for multiple joints as long as the materials have not set up, normally after 3 to 5 minutes of non-use.
PE FUSION Q & A
To achieve the perfect PE Fusion connection what procedures are necessary?
Preparation and thoroughness is paramount. PE Fusion should be applied to clean surfaces that have been “roughed up” or “scraped” using the scuff pad or pipe scraping tool. Scrape or rough up the joining surfaces including the conduit end and the inside the coupling and have all joints ready to accept PE Fusion. Once PE Fusion is applied you will need to work quickly and efficiently. The installer should wear rubber/latex gloves to avoid skin contact and to assist with the spreading and application of PE Fusion with his finger to the contact surfaces.
How do you use PE Fusion to make a connection?
Once all surfaces are prepared, insert the cartridge into the applicator tool. Remove and retain the cap from the cartridge. IMPORTANT - purge a small amount of PE Fusion out of the cartridge until you have positive flow from both the “A” and “B” components. Install the static mixer and extrude a small amount of PE Fusion until you have a uniform color, ensuring a true 10:1 mixture. Extrude the material onto the surfaces to be bonded. With your hand in rubber/latex gloves, use your finger to spread a thin consistent layer of PE Fusion onto the areas to be bonded. Connect the two surfaces and hold until the bond has ‘set’. After 3 to 5 minutes of non-use, the PE Fusion in the static mixer will begin to harden, when making multiple connections it is imperative to work quickly.
How quickly can a connection be made?
Working time is dependent upon the ambient temperature. At room temperature (72 F) you have several minutes to complete a joint, the warmer the ambient temperature the more quickly the bond will ‘set-up’. PE Fusion will normally set up in 3 to 5 minutes but regardless of the temperature at the time of application 100% cure time is 24 hours.
Is there an ideal temperature and conditions for making a PE Fusion connection?
The ideal temperature for using PE fusion is room temperature 70ºF (21ºC) but the working temperature that PE Fusion can be used is between 32ºF (0ºC) to 95ºF (35ºC), it is important to keep the cartridges of PE Fusion at the recommended storage temperature until ready to use. The cartridges should be stored at temperatures between 40ºF (5ºC) and 80ºF (27ºC), never allow the product to freeze.
Can I keep unused product for future use?
Any material remaining in the cartridge can be retained for future applications. Simply remove and dispose of the Static Mixer tip and replace the cap that was provided with the cartridge. Follow all of the instructions when it is time to make the next PE Fusion connection.
How Does PE Fusion compare to other bonding products?
PE Fusion is a product that chemically bonds polyolefin to other dissimilar materials. Other adhesives claim to be able to bond products and may look very similar but their two-part epoxy based mixture relies on a mechanical bond and is vulnerable to impact stress and is slow to cure even at room temperature. Test results verify when using a mechanical bond and adhesive failure is common with epoxy-based products as opposed to coupling failure with PE Fusion’s modified acrylic formula.
What makes PE Fusion different than other adhesives like PVC Cement?
PVC Cement is excellent for creating a chemical bond between PVC components. However, the bonding reaction that occurs between PVC surfaces with solvent cements cannot be achieved between PVC and other thermoplastics. Using PVC solvent cements to bond PVC and PE results in only a slight surface adhesion, not a true bond, that can be easily broken if the connection is stressed or impacted. PE Fusion creates a strong lasting bond between PE and PVC.
