Thanks for doing this test! A tip for mixing; I've found that old business cards are the perfect disposable surface for mixing things like epoxy. They're just the right size
You need a high specific surface area to maximize surface energy which you get best from sandblasting rather than sanding. Sandblasting gives you a complex surface texture (see Dan Gelbart's video on coatings). Also, Scotch Weld makes a line of adhesives (DP8005) designed specifically for low surface energy plastics like HDPE. It looks like the adhesive you have is for regular plastics. Cheers!
I used DuPont 5200 to glue a block hdpe to the stern of my boat so I had something to mount of transducer on. It’s been there for 10 years and not falling off.
I have tested so many glues over the years on this problem and finally found one that works. Scotch weld (3m) DP8010 and DP8010NS -ns is the non sag version. It’s like performing a magic trick when you realize the glue actually bonds to the surface and you can’t just rub it off. This glue is a very interesting Blue color
That 3m stuff is amazing. There are also cheaper good imitations.
which imitations? I'd love to test them

this sht is expensive as black caviar lol
and only $80 a tube 😂
@@epb22 Any suggestions ?
JB-weld for plastics works about as well as regular silicone caulk. Glue that have a separate primer/activator bond enough for non-load bearing projects. Glues that have a high strength bond need the joint scorched first or a hot glue gun or need.
I searched for a long time to try and tracks down a glue for making my rain barrels since I do not have a welder. So far so good. I had to call JB Weld to ask them if htye had a product and this is the stuff they recommended. There are some discrepancies though b/w packaging and online description. HDPE is listed online I believe.
Uniform plate heat each side until a little over 1/16 bead begins to form then immediately press evenly both pieces together until the bead is nearly 1/8 of an inch. Allow to cool or wet rag to quicken cool down!
My HDPE wheelbarrow was completely split and fragmented across both front bolts that fasten to the arms. It takes time because your working with a black powder and glue adhesive. Its called Q-Bond. $25.00/kit. Two botyles of glue and one botyle black powder for plastics and a gray bottle for wood, metal, glass ect. Worked like a charm. Very strong. Use it for hauling split wood. Throwing it in from 10 fert away is not a good idea. Still load wood but treat it as it should be used.
Just a little addition. Others have noted to scorch (blue flame treat) the HDPE, etc. I did this, following the Triumph Boat manufacture's instructions. The J-B Weld easily came apart and peeled off, just like in this video. . . It appears to the be same as a more expensive, other named two part epoxy system. . .
I believe that flame treating this thickness of HDPE should work out quite well. The key to success is checking the wettability of the surface to determine if you've flame treated long enough. Just put a drop of water on the surface and tilt/try to move the droplet across the bonding area. If the water spreads/sheets across the surface without beading up you've treated it long enough.
What works are some combinations of primer and glue specially designed for PE/PP plastics. Loctite has had such industrial products for 25 years, and consumer products for 10-15 years or so. The surfaces must be really clean, smooth and dry, the primer applied once and then the glue applied within 1 minute if I recall right. If you do everything right it will be a strong bond. Welding also works, but must also be performed with care and precision in order to be strong.
Thin (1.2mm) HDPE is usually bonded with heat rollers to permanently bond the pieces together.
I have joined HDPE together, in fact it was black starboard just like you used. It was done successfully with both epoxy and Methacrylate adhesive after passing a flame across the surfaces. I used two blocks 1-1/2" square, they are joined face to face not edge to edge but now after 5+ years I still cant break them apart with a vise and large wrench to twist them or a hammer. I also tried this with urethane adhesive and it failed miserably
I glue HDPE to fiberglass with Bostik 940A for marine applications. Silicone-Polyurethane hybrid adhesive. Comes in sausages only. Works well.
Thank you for saving me time.
LOCTITE PLASTIC BONDER for the win ;)
Thorough video, but glad I watched at 2X speed 😅,
Use a lot of HDPE for Ham Radio projects....DC distribution panels, go boxes etc. Have never had any success in bonding hdpe with any type of glue
Instead of glue try Friction Stir Welding, place something that looks like a metal drawer knob in a drill and use the heat generated from friction to weld the seams together.
Thank you so much - you saved me some $$$ I was going to spend.
So far no luck with HDPE adhesives. Here's what I tried, belt sander with 80 grit, the the torch as mentioned, applied JB Weld Plastic Weld left it overnight. I was able to remove the epoxy with my fingernail. There may not be a solution other than mechanical. I'm trying POR-15 Patch Filler and Seam Sealer now. I'll let it cure overnight and see what happens.
Replying to my own question. The POR-15 Patch Filler and Seam Sealer, really didn't work. It held but after some time, and use it failed also. Mechanical joining may be the only way,
Seems to me that shedding glue is the whole purpose of HDPE. Put it on your workbench when you're assembling furniture, and you'll never have to chisel a board off your bench.
I have had some success using super glue (Cyanoacrylate) by priming it first with MEK. The bond is not as strong as the HDPE, but adequate for some things not subjected to a lot of stress.
Permabond TA4610 works on PE, but not edge to edge like that. You need a larger bonding surface.
Good video. I have an hdpe chainsaw oil reservoir that had a brass pipe glued in so talk about a bonding nightmare. Not sure how it was ever attached to begin with. I'm going to try epoxy but I'm doubtful it will work.
Try Polywater® BonDuit® Conduit Adhesive
Create strong, watertight and airtight bonds with HDPE conduit glue 😀👍
We glued on a 3" pvc coupler with the Polywater Bonduit onto the end of an HDPE roll duct then dragged the 8' tall reel of the duct around the yard with a forklift to try and pull it off. It stayed on so we use it to couple HDPE roll pipe. 40,000 feet of 4" on that job.
Hdpe will only bond to hdpe do if you wanted to weld it . So if you want weld use hdpe pellets or another hdpe scrape as welding with heat gun with precise temperature control to bring hdpe its fuse point then you can weld it. Do not use flames on hdpe since when it gets to melting point it will flammable.
What if you scratch the surface you are about to bond first?
I'm thinking thin strips of metal strapping or wood like a whiskey barrel maybe each piece screwed in.
In trying to make a mount for my trolling motor for my kayak I need to bond a block of HDPE to the end of an aluminum bar. I found and appreciate your video but also found the following products supposedly will work. Would you consider testing the following 3 products?: Permabond TA4610 is made specifically to bond polyolefins including HDPE to materials including metals; 3m Scotch-weld Structural Plastic Adhesive DP8010 structurally bonds polyolefins with no special surface prep and bonds to dissimilar substrates; and Loctite AA 3035.
That’s a long video for something that doesn’t work.
Thanks dude you just saved me 12 minutes of my life.
Hmmmm. Never remotely occurred to me to try bonding edge to edge. Can't think of a single reason I would have to do any kind of edge glue-up.... Need to bond a 38in x 19in piece of 3/16in thick HDPE to a workbench top made out of a crummy grade of MDF. Flat to flat. Theoretically, by pure amount of surface area the bond would be vastly stronger... NOrmally would use screws from underneath, but 3/16in is a little thing for screws to gain purchase on without pushing through.
Internet is saying cyanoacrylates work well on HDPE Don't know yet. Will run some experiments tonight with what I have around the house and post the results here later.. Wish I could find the old, thick, transparent yellow-orange rubber cement-like contact cement goo we used to use when I was a kid. Best contact cement ever! Worked great on wood, leather, Formica, cardboard, concrete, carpet, and metal. But the fumes would rot your brain into jelly! I could actually smell it through the sealed can at about 20 paces. Would love to see how it would've done on this stuff or Kydex.
The new MMA adhesives do work for HDPE, PE, LDPE, etc.
TAP poly-weld?
Why glue it when it welds together so easily?
Also, try marine jb weld
Thanks! Can you use a Plastic welding kit for HDPE? I saw a video for that. I have a CRACK in my motorcycle
saddlebags
permabond TA46## range, TA4630 or TA4605 there are 5 or so varieties depending on your applictaion
I'm looking to bond small HDPE strip to a painted plywood panel. Would this product work? Or what would you recommend?
Thanks for this test...
I see no more reason to apply epoxy to both sides than with any of the other epoxies I use [by the gallon]. If you've applied enough to fill any voids and cover all the surfaces, you should be fine.
Hi, probably Sika primer for Polycarbonate can do the job for better grip and then the stongest Sika glue...
West Marine 655 or 650. Follow the directions. Flash the plastic. I repaired two Kayaks and a canoe with it.
You mean West Systems gflex
There's a marine grade that you can weld hdpe with. Its in a blue package . You're supposed to be able to weld the plastic on kayaks with it.
Any chance you have a manufacturer for it?
@@chasihler i think loctite makes it
This is exactly what I'm trying to do
there are primers out there and then adhesive for hdpe try please
Try JB weld original (not plastic)... After sanding the surface
All sanded edges need to be wiped down with alchohol or acetone. prior to gluing from what i have read from the starboard manufacturer.
YOU'RE NOT SUPPOSED TO MIX ON CARDBOARD. IT ABSORBS SOME OF THE CHEMICALS. MAYBE USE I DON'T KNOW.... A FLAT PIECE OF HDPE?
Thank You.
Can I glue it to aluminum?
Thermal fusion
Try heating up the hdpe surfaces you are apply the epoxy to with a propane torch first.
Try elastomeric silicone.....Not really for strength but sealing HDPE This is what I use www.walmart.com/ip/Sudbury-300-Elastomeric-Marine-Sealant-White-10-oz/43366744?wmlspartner=wlpa&selectedSellerId=2605&adid=22222222227031444444&wl0=&wl1=g&wl2=c&wl3=56391337736&wl4=pla-100839545576&wl5=9005530&wl6=&wl7=&wl8=&wl9=pla&wl10=126803975&wl11=online&wl12=43366744&veh=sem&gclid=Cj0KCQjw-_j1BRDkARIsAJcfmTG8xmePzAQ3ZXq5ybhF_-NxitNQo89raTATjgEuBlW04pTO6kiqvrkaAso2EALw_wcB
Flame Treating or Corona Treating makes HDPE bondable. No tickey-no laundry
West Systems g flex epoxy is supposed to work
Where do you source your HDPE from?
Anyone try 3M's windo weld 08609 urethane on a blue rain barrel yet??? Nasty looking stuff, but when it cures, it's really tough.
Is it possible to bond HDPE to steel? If so what would be the best adhesive or method for fastening?
Tap and bolt together … good luck!
Good test , Saved me some time ! but not quite accurate summary, HDPE .. CAN... be glued quite well. I make watertight vessels with it.
Methacrylic epoxy does a chemical bond that is stronger than the parent material. I'll have my video tests up on my youtube channel openning next month. ( ppinthewoods ) The only manufacturer that has been 100% for me is Loctite 3035. It is expensive epoxy but works exactly as advertised. There are several reasons NOT to heat any plastic if you want it to retain it's original chemical properties. That is valid for most all plastics. While most hdpe is thermoformed, a secondary heating after cooling changes the molecular structure yet again.
Thanks again for sharing your test ! well done, Phill
Thanks for the comment Phil. I look forward to seeing your video when you launch.. drop a link when you do.
Should have done more research. Oxidize the materials with a heat
Do you think using hot glue will work for bonding HDPE?
Not to sound like a pessimist, but hot glue doesn't have a good bond on anything!
Thanks for doing this test. There's another youtube vid I found with a guy, Roy Niswanger, who tests out a few other products that look very promising (th-cam.com/video/sooI6QZCBH0/w-d-xo.html). I'm going to go with the Loctite he found to work well.
You first need to heat both surfaces with a torch (not melt) to allow the adhesive to bond properly. Watch video. th-cam.com/video/h-9yhanz5DE/w-d-xo.html
Hot glue will bond HDPE together but it's a fairly weak bond. I works for gluing two pieces face to face not good for edge gluing.
Loctite AA 3038 A&B
Contact cement maybe?
Searching tonight because of a job tomorrow. In the past we have used spray contact adhesive and staples to put two sheets of 3/8 together for 3/4 in certain places… tomorrow I am thinking, spray glue and 5/8” screws
Tap POLY-WELD ADHESIVE. 2000 PSI ON HDPE
My current package says not for PE
I used it anyway with superglue (for plastic) beneath. Seems well bonded.
NO Gloves???.......Interesting!!!
I recently saw a video on HDPE and thought you might want to try this TAP stuff at th-cam.com/video/h-9yhanz5DE/w-d-xo.html
Loctite 3035
why not try the heat you big baby
You probably could try to heat up both sides with a hot heat gun and then squeeze them together until they fuse/bond...you would need to use clamps to hold. I work for a company that installs HDPE piping and it is done kind of the way I explained above....but at a much bigger scale.
Here is vid showing what I am talking about
th-cam.com/video/EeT0INfIRn8/w-d-xo.html
JB Weld sucks - every time I have used it on every material, it fails. I have no idea how they stay in business.
That is bumper filler , it wont work
he says its HDPE but it looks like ABS to me ...
It was starboard HDPE. Starboard has that nice finish.
LONG STORY SHORT!....DONT WAIST YOUR TIME!....IT DIDN'T WORK!!!!!!!!!!!!!
