Best Glue For Polyethylene

#1.J-B Weld Plastic Polyethylene Bonder

The J-B Weld Plastic Polyethylene Bonder is in our opinion the best glue for polyethylene because it really gives you that industrial bond strength while being easy to use. The tensile strength of the bond is rated at 3770 PSI and if that’s not enough for you, then you are kind of out of luck. This stuff sets in about 15 minutes and can be sanded in around 30 minutes.

This gives you plenty of time to reposition and readjust your angles. Furthermore, we really like the fact that it can endure through some pretty extreme temepratures, which we can’t say about the others. And being one of the easier two part urethane bonders out there, there’s not much to pick at it other than it dries to a light tan color and not clear. But J-B- Weld also sells clear ones.

#2.Permatex Plastic Weld Adhesive

Next up, we have the Permatex Plastic Weld Adhesive, which is the best glue for polyethylene if you want a structural adhesive that is fast curing and requires no primers. This adhesive cures in just about 5 minutes which is much faster than the J-B Weld mentioned above. The trade off is that it is just a little less strong, coming in with a tensile strength of 3500 PSI.

Also it settles to a cream like appearance, which is way more light and blends in better with everything than a more tan like color of the J-B- Weld. And it does fairly well with various temperature ranges as well. The only thing you have to give up is a bit less bonding strength, but it really isn’t that noticeable anyways.

#3.Gorilla Clear Grip Contact Adhesive

Another great option when it comes to the best glue for polyethylene is the Gorilla Clear Grip Contaact Adhesive. This thing is 100% waterproof and dries nice and clear instead of a tan cream color. The trade off to the Gorilla Glue over the above mentioned brand is that there is a significant loss in bond strength. Don’t get us wrong, the bond strength is still amazingly strong.

But it is nothing compared to the above brands in terms of tensile strength. However, the trade off is that you get a bond that is more flexible, paintable when cured, and fast grabbing. It also has a no run formula that dries pretty fast. This can be a good and bad thing, depending on how you see things and how fast you work.

#4.Loctite Super Glue For Polyethylene

The Loctite Super Glue For Polyethylene is clearly a great product and we put it on our top 5 list because it simply is a great brand with a good reputation for making quality glues. Believe it or not, brand reputation is quite important in this industry as there is plenty of crap products that just don’t make the cut for making quality reliable glues. Luckily Loctite isn’t one.

We like this glue because it is quite easy to use and is quick and neat with no mixing required. It has a pretty short setting and cure time and and doesn’t make a mess everywhere. We like that it doesn’t take much to create a really strong bond. Also, the activator does a really good job of priming hard to bond materials such as polyethylene.

#5.Starbond Super Fast Thin Cyanoacrylate

Lastly, we have the Starbond Super Fast Thin Cyanoacrylate, which is a relaly nice super glue that gives you a very precise application. While it doesn’t have the priming ability of some of the above mentioned 2 part systems, it is good enough bonding just on its own and is certainly much easier to apply.

We really like the applicator tips that it comes with and the capping systems, which do a great job of making sure there are no clogs and that you properly administer the glue precisely where needed. Lastly, the applicator tips are long enough such that you can really get into some nice cracks, crevice, and bend around corners. This is a nice bonus that many other brands don’t have.
