20 Best Glue For Polyethylene (2022 Updated)

I like Permatex products but not this one. I will go back to my run of the mill clear epoxy. Would not buy again as it was weak. I clamped the item and left it sitting for several days — no excuse for poor performance.

I scoured the internet to find an epoxy to fix a fresh water polyethylene tank leaking through couple of cracks around the outlet fitting. Everything I founds advised no glue or epoxy will stick to Poly-E so I contacted the RV dealer who said the same and a replacement would be $700.

I found this on another site and the description actually said good for poly E, however picture on this site does not state this. Luckily a previous reviewer on here confirmed it worked on his rv tank so I tried it.

I did a similar technique 1- partially removed the tank to get full view and access of the cracks. 2 – drilled small holes at the end of each crack line to prevent further spreading. 3 – Light sanding of the area (and around the fitting) with #80 grit paper enough so that the surface feels rough and gives epoxy something to stick to (sand a larger area than the cracks so you can epoxy a little further).

4 – wiped area and cleaned with ISOpropyl alcohol to make sure no fine particles remained. 5 – Applied a single consistent layer of epoxy over the entire area of cracks ~ 6″ x 6″ and encased the bottom of the fitting to ensure 1 consistent layer (1/2 of Tube in my case).

It is still tacky after 15 minutes so I let it cure for 24 hours sanded the first layer to rough it up, cleaned then applied the remaining half of the tube as a second layer. I let it cure for about a week then filled with 40 gallons of water and took the trailer on a easy 2 day trip, worked no problem.

I then waited a month and went on a 2 week trip hauling full tanks through extreme traffic (had to lock the brakes up on truck and trailer), bumpy roads, 40+ degree heat wave etc. and it has held so far.

JB Weld plastic bonder is incredible: fast (sets in 5 minutes, cures in an hour), easy to use and holds forever on flexible surfaces. Backed into an oddly placed pole in a parking lot some years back and broke the attachment point where metal screw mounted plastic bumper to our Nissan sedan.

$Hundreds to repair/ replace? Nope. JB Weld plastic bonder reformed the break point, over night set and screwed that baby back on the next day. Years later we sold the car and that ‘plastic weld’ was still holding just fine.

Around same time some knuckle head knocked off the cowling on my passenger side mirror on my parked MB C280, cracking the mounting ring. Ouch! Joined the broken ring with JB Weld Plastic epoxy and popped the cowling back in place next morning.

That was 6-8 years ago. Earlier this week a new klutz walked into the same repaired mirror, this time breaking off the bottom of the mounting section. Here we go again. JB Weld to rescue; ten minute repair, cowling goes back on tomorrow.

Great stuff for tough plastic parts. Strong bond that’s firm without being brittle.

The JB Weld Plastic Bonder worked great! It produced a really strong repair for some plastic fastener extensions that had broken off of an automotive seat plastic trim piece. I roughened the plastic pieces and spread the plastic bonder generously over the repair area, then tested the strength of the repair after it cured.

I’m happy to say that I’m confident the repaired pieces will be less prone to breaking off than they were originally.

I have been using this product for years, I can not buy it locally any more and am glad that I can still get it through eBay. Many of the newer products mix so wet that you cannot get them to fill a crack in plastic; it just drips through.

This product is very thick even after mixing the two parts together.

Bought this to carry out a repair on the embellisher on a lotus headlight. It’s the typical low quality plastic that is known for easily cracking when even a small force is applied. This plastic is called PPO and research seemingly says it’s hard to find an adhesive that will work successfully.

As it turned out I used a pretty standard rapid epoxy to bond an aluminium strengthener and it worked well. This plastic bonder was excellent when it came to building up the missing sections of plastic that made a bridge over the aluminium section.

Easy to dispense and mix, this is also easy to apply. Building up a decent amount wasn’t too difficult, it can move with gravity but after a few minutes it has stabilized. It has bonded extremely well to both the plastic and also the aluminium I used.

Big bonus is this is black in colour so matches the original colour, unlike the previous owners attempts with glass fibre which were stand out red! New embellishers are 550 pounds plus vat, so this product, along with a couple of other items adding up to 30 pounds, have created a far stronger product.

Very happy indeed.

Rough up the areas you want to glue together and remove any dust from the sanding. Apply glue to both parts and clamp together. Add a little more glue to the crack. It will start setting up in about 15 minutes.

Let it harden for a full 24 hours. Any extra you added can be filed or sanded off if you don’t like the look. I used it on a plastic lawn chair and I weigh 250 lbs. and it didn’t come apart. Very strong tough stuff.

I highly recommend this product.

Great product, many uses, best price here. Small size has both advantages and disadvantages, but great for most smaller projects. Sands well, can be shaped when set. Easier to get into tight spots with static mixer than larger panel bond applicators.

When you patent a reusable static mixer, you’ve hit a gold mine.

Excellent adhesive that dry up when I use it again on next application.

This product IS NOT for the novice! It almost works too good for the professional. Thread locking is virtually instantaneous. Just the small amount of heat generated when threading two items together will initiate locking.

If there is a future plan to separate the parts bonded, use a milder form of locking agent, such as Loctite Blue. If misalignment can occur, dry fit all parts BEFORE bonding. Make locating marks, and mask any part that should not be coated with this adhesive.

Super bond strength. Test thread bonding on similar, but sacrificial, parts first. Freezing threaded parts may slow the bonding action. YOU GET ONE CHANCE! No joke. Use sparingly.

As time has passed, more and more items have been broken never to be reassembled. until now. A broken pet’s headstone of granite fixed. A ceramic bobble-head chihuahua’s head broken at the neck fixed.

A brass plate separated from a granite headstone reattached. A glass ornamental soap dish shattered but now reassembled and no leaks. I don’t know what this stuff won’t hold together if anything. maybe air molecules(?) I recommend this to anyone who wants to fix something worth saving.

One last thing. when I used Super Glue in the past, after opening the bottle, using it and setting it aside for a few days the opening would be crusted and the contents would eventually dry out. Not so with this product.

It flows from the container as if just opened each and every time you use it. No crusting, no fuss, no muss, sets quickly and the container is easy to handle so that you don’t get any on your fingers/hands.

The cap “snaps” when it is sufficiently closed; not like other glues of this type where you don’t know if you’ve “torqued” the cap sufficiently to prevent evaporation. If you’ve got something that needs to be reattached/reassembled, get this LOCTITE product and get it Back Together!.

Glued a plastic base to a stainless steel travel mug that kept coming loose. Base screwed to another plastic portion, stainless was middle sleeve of the mug, Ran the mug through the dishwasher, still stuck, can’t undo it.

Wondering how many time I can run it through the dishwasher before I can tighten it up a bit as I didn’t get it quite like I wanted it. Holding strong, sets quickly, basically it’s a quality super glue, colored black.

Don’t get it on your fingers or other things you don’t want it on. I will buy more when I use this up and need more.

I only recently heard about Plastic Magic, so I thought I’d get some and see what it was like. It works beautifully as a polystyrene cement on model kits. It has a capillary action in a similar way to Tamiya Extra Thin, but smells a lot less.

I have found it to be very good at cementing clear parts on model kits without clouding the pieces as some plastic cements do.

Works great. Just like always.

Welds polystyrene to polystyrene. Don’t use it on PVC such as Bones or Nolzur’s Marvelous Miniatures.

I didn’t realise this glue said flexible until after I had glued the amulet (plastic to metal) back together. I had to put a book on it and leave it in the path of a fan heater for it to stick. The instructions say something quite different that didn’t really work for me but I’m just glad i found a way to make it happen as I had a client coming within the hour.

My method applying heat and pressure seemed to work well and it’s been a few weeks with no complaint so I would use 85 again and it was infinitely more effective than the superglue I tried with an earring last time.

The instructions clear and concise, all and any of my specific ‘glue problems’ were solved. A very excellent product.
