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

[@waldtricki]

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

[@epb22]

That 3m stuff is amazing. There are also cheaper good imitations.

[@waldtricki]

which imitations? I'd love to test them @@epb22

[@pecatum666]

this sht is expensive as black caviar lol

[@luminousfractal420]

and only $80 a tube 😂

@@epb22 Any suggestions ?

[@neverwipe]

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.

[@jkg6211]

You meant 3M 5200 ?

[@johnsoleimanian]

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.

[@brotherlove100]

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.

[@harveyfloyd6045]

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. . .

[@jeffk3192]

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.

[@777fiddlekrazy]

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!

[@davidreynolds4684]

Lock time makes a cyano with an activator that looks like a magic marker. The trick to it is the prep work. Clean very well with soap and water. Dry well. You'll be tempted to use alcohol. Acetone ,or other chemicals and at times they will work but they can leave a residue which can cause the bond to fail. I've had very good luck welding it. I've welded about every type of plastic you can find. The trick is knowing what type plastic youre working with. The temp and repair material can make a big difference in your success in many types of plastics

[@mikev7396]

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.

[@oskarenoksson9626]

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.

[@timgriffin-lv7vj]

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

[@panamdragonboat]

I glue HDPE to fiberglass with Bostik 940A for marine applications. Silicone-Polyurethane hybrid adhesive. Comes in sausages only. Works well.

[@jagboy69]

Thin (1.2mm) HDPE is usually bonded with heat rollers to permanently bond the pieces together.

[@williamterry3177]

Thank you for saving me time.

[@jay-rus4437]

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

[@jimwoodmansee]

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.

[@19sloper]

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.

[@peacefulscrimp5183]

Great video 👍

[@SwitchToRumble]

[@gregrobbeloth8926]

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.

[@TheGraemeEvans]

permabond TA46## range, TA4630 or TA4605 there are 5 or so varieties depending on your applictaion

[@darkdelta]

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.

[@darkdelta]

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,

[@_WeHaveFun_]

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.

[@tomsawer8696]

Thank you so much - you saved me some $$$ I was going to spend.

[@DanBellJr]

Try Polywater® BonDuit® Conduit Adhesive Create strong, watertight and airtight bonds with HDPE conduit glue 😀👍

[@DanBellJr]

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.

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.

Permabond TA4610 works on PE, but not edge to edge like that. You need a larger bonding surface.

[@daz4312]

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.

You first need to heat both surfaces with a torch (not melt) to allow the adhesive to bond properly. Watch video. kzbin.info/www/bejne/nl6cqpuXo99oeqc

[@kellyvcraig]

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.

[@thePods]

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.

[@phillpittman587]

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
