Which Epoxy is Best for Plastic? Let's find out!

I've had hundreds of comments requesting I create a video testing which epoxy is best for plastic. Are epoxies designed for plastic as good as those designed for general purpose? Which name brand is best? In this video, I use 3 tests to determine which epoxy is the best.

Thank you very much!

NO KIDDING! He’s actually caused me to change brands on a few things I’d used for years. It’s funny how advertisers quit marketing to people above 35 or 40, since we’ve normally found out stuff and dont change brands. WRONG! Project Farm is better than Consumer Reports to me. This is a real world test, in metrics us folk that use things actually apply things and can see things in our normal daily life.

[@ProjectFarm]

Glad to hear!

[@BJ-fk9sq]

Was the broken piece plastic to plastic? Did you fix it?

[@bassiclymike]

Interesting test. A couple points to consider: This is for one specific type of plastic (nylon?) bonded to steel. There are several other types us folks who repair our own or other cars also see: styrene, polystyrene, polypropylene, various types of polyelthylene (HDPE, LDPE, PET), polyamide. Would be very interesting to see the results with each plastic type as they all have different properties. How about the plastic bonded to itself for each type, such as when the home mechanic attempts to repair a plastic part? Often this is the only recourse, as folks like myself encounter broken plastic parts and replacements are not available. I rarely need to bond plastic to metal, but plastic to itself is of great interest. I look forward to seeing such a review from you!

[@ProjectFarm]

Thanks for the suggestion.

[@stevelaferney3579]

Yes! Thanks for all you do but yeah plastic to plastic is what I need and what I usually need. Thanks again. You do us all a great service. Really.

[@paddledogs]

I was going to chime in here and say that nylon is way different from most of the plastics I deal with. It would be interesting to use non-nylon in some tests. Also plastic 2 plastic would be really interesting.

[@topherteardowns4679]

it would be great if you tested how well they bonded to one another, and then done the subsequent tests. Id love to see gorilla on the bolt and jb weld on the metal. There is a dozen variables you could explore, regarding the curing times and which is bonding to which, etc.. love your channel. top notch!

[@kkepdawg1]

I was watching super glue and mixing baking soda with it. Even ash's and super glue. Amazing results! So what super glue mixes with a control using different ash/soda's. Strongest to hold weight, how they cut, sand. The other variable is using release agents. I have seen grease, wd-40, motor oil, or aluminum tape and masking tape. Long time sub. Hope you at least see this??

[@Mattlawton-ft6ew]

Try 3m scotch weld 👍

[@steve.hoffman]

This review saved me about $1,000! Based on your tests I got the Loctite to fix a broken door handle on a high-end GE microwave. The handle had snapped off in a weird way because the screw fittings are all plastic. I think the flex test is the one that convinced me, based on pull and shear from normal usage. Found out this is a common breakage complaint with our model. Can’t just buy the handle without taking the door entirely apart and requiring some radiation testing above my pay grade. One week after application and a 24 hour cure, and it is still holding like it was never broken! And I’m a hero in the home! Thanks again!

[@blipco5]

This was a very tough test. You used nylon bolts. It is very difficult to get anything to stick to nylon. Good job as usual though.

[@ProjectFarm]

This is a great point. I plan to test plastic on plastic soon. Are there a few plastic glues or epoxies that you recommend I test? I'd like to stay with the consumer price range if possible. Most people aren't willing to spend $30+ on a plastic repair.

[@blipco5]

PF....I can't off hand think of any specific plastic epoxies but I have used JB Weld Original with fiberglass mat to join broken motorcycle plastics together with great success.

[@bhartley1024]

[@lewiemcneely9143]

......and I'm one of 'em!

[@Spectt84]

Original J.B. Weld never ceases to amaze. It's the only one that I have had any real experience with (once I needed something to be clear in color and tried some generic 5-min stuff other than that I think it's always been j.b. weld) and I kind of felt myself rooting for it to outperform the others. Based on my past experience & your tests I think it's safe to conclude that you can't go wrong with regular 'ole J.B. Weld.... Next they need to figure out how to make it clear in color. Then there is absolutely no use for anything else. Great video, going to save me from reading the backs of 50 different epoxy packages just to choose J.B. Weld in the end anyway because there is too many choices and variants. Plastic specific epoxy seems like a gimmick when something made for steel outperforms them on plastic. Thanks for simplifying my life just a tad bit...

[@ProjectFarm]

Thank you very much for the positive comment! All of the clear epoxies seem to have a similar smell, which is much different than the epoxies with colors. I wish they could make a JB Weld formula that was clear and as good as the original.

[@Wooble57]

I think original JB is reinforced with tiny strands of steel, probably where most of the grey color comes from.

[@Paul-pj5qu]

Spectt84 They do now have a clear formulation. So far, so good on plastic to plastic, but it is not all that right an application I am using it for, but others did fail.

[@jusb1066]

i wonder if they could instead of using steel to reinforece jb weld, to use glass fibre? then it would be strong and clear too?

[@milesabove5259]

Honestly i think this video gives you more than whats the best single product, its more of the correct application for the specific use of the products tested. I love both loctite and jb weld, but knowing what to use in each application is the most important thing.

[@USNBRENDON]

I wanted to see you do THIS very project and requested it in the past, so THANK YOU VERY MUCH for the incredible work you do and for always being so logical, thorough and unbiased in all of your project setups, testing protocols and final analyses! I am a huge nerd who loves to learn but does not have the means, nor your degree of expertise, to perform ALL of the various product comparisons I've always wanted to do in order to work smarter--not harder. It is for this reason that your channel and the almost unbelievable plethora of project farm head-to-head tests / comparisons make my life so much easier. Without your high integrity testing methodology and truly unbiased approach, I'd be forced to rely on far more subjective "reviews" (too many of which shill for a particular brand unbeknownst to the consumer), or I'd have to accept the fact that many of my projects would quite likely have a higher degree of inherent failures due to lack of real-world data points from which to extrapolate the BEST or MOST SUITABLE product to meet my unique needs. Again.....working smarter, rather that harder, means I don't want to have rework, especially if it occurs multiple times for something that could have been avoided had I done sufficient research or had access to the kind of unbiased, side-by-side, practical comparisons that not only provide a simple excel-type table or spreadsheet of relevant specs & data points, but I have the advantage of being able to be a fly on the wall in your shop and to soak in the knowledge as I have time and need. One great thing that I've discovered over time by watching numerous head-to-head roundups here is that in nearly every case where I've performed similar tests--often ritualistic and very OCD-like tests to help me get over my anxiety & worry of choosing the wrong product for a task--or by trial and error I've learned volumes on what DOESN'T work, I find incredible comfort and satisfaction in discovering that YOUR TESTS SO OFTEN CORRELATE WITH MY REAL-WORLD FINDINGS. That has provided me a good measure of faith & trust in my own abilities to make accurate assessments and to logically discern the critical information necessary from so much of my everyday life; whatever the days bring my way and what will be next on my list of repairs, maintenance and upgrades to home, auto & tech! I know that's a LOT to read, but it is sincere and from the heart, thus I believe it carries more weight than a mere "thank you," even if that expression of gratitude is in ALL CAPS. LOL Again....I hope it is truly fulfilling for you knowing that you help so many through your work here on the channel. I realize this is NOT easy, nor cheap to pull off. Hell, the video editing skills alone are worth their weight in gold and I wish I could pick your brain on that subject as well. Happiest holidays to you and yours. Namaste. Cheers!

[@JV-wl6ex]

It makes a big difference on which type of plastic you are trying to bond with. The different polyethylene types, polypropylene, polystyrene, and PVC all need different bonding agents to make a successful plastic weld. Picking up a regular off the shelf epoxy from a hardware store is asking for bond fail. Thanks for the video!

[@moderaterevolution504]

Any tips on what kind to use for a car door handle? I would be "gluing" the front plastic piece onto, another piece of 3/4 inch corner mold. I could buy the corner mold in a specific type of plastic when I go to buy it.Then the other side of the corner mold will be glued onto the part of the door handle that remains on the car. This is one of those pull upward door handles. Thanks for any ideas.

[@corydalus981]

Speaking as a person who has actually designed research projects, I must say that your experimental designs are very well thought out! You put a lot of effort into minimizing extraneous variables. Gluing plastic is almost always problematic for me. Nylon is naturally "lubed" so especially tough. Same with polyethylene. Not much sticks to it, except labels when you want to remove them.... If I can, I will do bizarre surface preps like cutting holes or slots, sanding etc, and if using a suitable glue, I'll overglue to embed the parts in a blob of the epoxy. If faced with butt-gluing small plastic bits, I usually don't even try.

[@ProjectFarm]

Thanks!

[@edwardmylnychuk5774]

yep i would agree some plastics are made so nothing sticks to them very well, using a solder gun to melt some metal to them and then glueing that would probably work

Would be an interesting test, though we use what might be better called a solvent for such things, such as WeldOn 4. In the end, using it, two pieces look like one and are welded together.

[@ADefenestrator]

In some ways not as interesting, since same-plastic can be welded. Finding something that'll bond it to metal is much trickier.

[@Ris-v4w]

@@ADefenestrator but interestingly enough all over the internet you see mainly people trying to glue broken plastic parts back together and having very low success rate. welding doesn't really help if you don't have the same material to use as a filler to weld the 2 broken parts, because if you weld plastic you melt a lot of it on the contact, and where you can't spare those 1-2mm of material to melt away.....you are just stuck(and not in the good bond success way :) ). and most people just have problems gluing plastic to plastic, so i'd say this would be even more interesting than just trying plastic to metal or other materials. you can clearly see also in this video that it's the plastic which presents issues for all glues to bond to it

[@MstrRo]

Sorry if I missed it, but what was the plastic bolt made of? Was it polyethylene or Polypropylene, Nylon, etc.

[@Allazander]

I don't think he said, I watched the beginning again and the text just said "plastic bolts". It's a great question though, especially since some plastics are harder to glue and are more chemically resistant. I'd be interested in the answer.

[@mengel420]

[@ProjectFarm]

Thanks for sharing!

[@rcplayland]

Again! Great information!

[@Raul28153]

The Loctite was quite impressive. The bolts you used are nylon, each plastic has profound differences in how they perform and react to things. Here's a tip taught to me by an old-school mold guy. Take a piece of known plastic and light it on fire (all you need is a sliver) Blow it out and sniff the smoke. NO TWO PLASTICS SMELL ALIKE and the smell is so strong you'll never forget it. All ethylene family plastics give off oils, To bond to them ya gotta remove the oils and since there's always more trying to come out it is a really improbable proposition. We used to use E-Beam Rastering to flash off the oil with some success. Some.

[@stoneblue1795]

how often would a person have need to glue plastic to steel? more of a case or need to bond plastic to MORE PLASTIC of the same nature unto (on onto) itself me thinks.

Came across this video for this exact reason. Broke an RC helicopter landing gear leg and was curious what the best plastic to plastic adhesive was. Still a great video though! Would have liked to see Devcon plastic steel too although. 👍👍

[@Ricopolico]

The best for plastic-to-plastic WAS Devcon MVP 33. It was so good, they stopped making it. The next best was Devcon Plastic Welder. ALL the other so called "plastic welders" are not nearly as good. These conclusions result from trying many products over many years. "Crazy glues" might grip great at first, but, in my experience, they do not hold up over time.

Thanks to your test, I will just give good old gray a try.

[@seanprice8999]

What a crazy test because I tried J-B weld original to fix the top corner of a plastic radiator and it cracked again. After cleaning and sanding again, I used super glue and baking soda on the radiator on day two and the radiator did not crack on the way home from work this time.

[@bigguns45acp]

Great video as always. Part of the problem may lie in the type of plastic used to make those bolts. Delrin, Acetal, and Nylon 66 are examples of Copolymer and Homopolymer's that leach oils. There is a high probability that those bolts had lubricants added to them to provide lubricity to reduce friction, heat and to prevent galling when tightening on the matching nuts. These types of plastics leach oils and can prevent glues and paints from sticking to them.

[@garthok1596]

Mostly nylon might as well have been silicone.

[@TheSprinterVan]

I have never seen you test in epoxy called pc-7 Growing up in the Northeast it was our go-to product. 40 years ago I remember standing in a hardware store as a child admiring this little statue they had on the counter that was a demonstration to pc-7 strength. A bottle filled with colored liquid with nuts and bolts and golf balls glued to it he could not pull apart. we use pc-7 on a variety of projects over the years and never were disappointed. I believe it is an equal to the original JB well if not better. Maybe a showdown pc-7 vs. J-B Weld? Anyways, another great video thanks

Use a high temp cooking oil as a replacement for motor oil.

[@ProjectFarm]

This is a great suggestion. I'll test this soon!

[@JRobert111111]

Cooking oil won't work as it, along with non-stick sprays only work to prevent the food from sticking to the pan. If these products are used in a "friction" type function, it turns into a very sticky glue like substance and would lock any engine up very quickly. I know this as I used to repair a lot of food preparation equipment and many folks would use cooking oil or Pam to lube something like the slide rods in something like a meat slicer. Then when the whole assembly became a solid mass, they were shocked at the expense as this crap has to be scraped off with a razor blade, then a wire wheel on a bench grinder and then still cleaned with solvent to make it usable again. I also learned at a young age about this when I had one of those neat Visible V8 engine models with the electric motor in the starter housing and the distributor actually worked turning on lights where the spark plugs were. The instructions said to use cooking oil to lube the cylinders. Needless to say, my model totally froze up quite quickly. If I get my hands on another one of these exact models (not the hand crank one), I now know better to use mineral oil, or the food machine oil which I still have plenty of. Just my 2 dollars worth.

[@bhartley1024]

I once used regular superglue one some bolts holding a pull starter on portable generator. When I had to remove them later the bolts wrung off with the nuts still glued on.

[@Wooble57]

i'm sure there will be some variability, but most strong threadlockers require heat to loosen (without heat you can literally twist the head off the bolt) It might be interesting to know the strongest that is still removable without heat though.

[@otm646]

In the fastener of testing industry what you're talking about is a very common test. All you need is a clean degreased nut. Run the nut fully into the thread locker, let it cure, then measure peak removal torque.

The engineering company develops and produces precision testing equipment, the most common one we make is for torque measuring. The torque measuring system is most often used by beverage and pharmaceutical companies for testing cap install and removal torque but the system is very adaptable for measuring torque on just about any application, its an extremely precise and repeatable tester, I bet that it could even be used for the common test you mentioned otm646

Does adding sawdust or metal powder to epoxy help? I’ve seen forged in fire contestants do this a few times and science doesn’t seem to support it.

Have you ever tested rapid fix 2 part adhesive. curious how that holds up.

[@riccocool]

Slower adhesive is always better adhesive.

[@JoeStuffz]

JB Weld again, and again, my favorite part about JB Weld is the two tubes. It's so easy for a single tube adhesive to gum up at the opening of the tube. I do wonder if the dual syringe design would be good against clogs for the kind of person that only needs a good, occasional adhesive. That being said, I'll probably stick with JB Weld as the default

[@ProjectFarm]

Thank you!

[@GnatGoSplat]

Love your vids! I'd also like to see plastic-to-plastic, specifically ABS. I'm guessing those bolts were nylon? Nylon is more resistant to solvents than ABS, so these epoxies may perform better with ABS. Majority of the time, when I need an epoxy, it's to glue back a mounting tab, joint, or bracket that busted off some ABS plastic snap-fit thing. Lately, I've been repairing broken plastic things with LOCTITE 11C Hysol instead of my regular go-to, JB Weld. I'm curious how it compares.

[@Pokka676]

Exactly. test failed. trying to find out the best plastic epoxy but proceeded with a metal base frame.

[@dmo848]

Try 2 part plumbing glue. Or straight up black abs glue for putting together pipes. I've used it and it has never ever broke

[@earl60446]

Another good job on the testing, JB Weld has always been my go to for epoxy. Nice to know I was right at least once in my life.

[@aWhiskeyTangoFoxtrot]

Nylon is a polymer. "Plastic" is a polymer, The problem is there are a lot of "plastics" so what one, each have different properties.

[@gamecapturemoments1]

@@ProjectFarm Also try ABS plastic sheet instead of the steel, since you are testing plastic bonders? Otherwise great video as always.

[@iskandartaib]

@@gamecapturemoments1 Yup... lots of different plastics. Actually I think there'd be most interest in bonding metals to, say, carbon fiber reinforced epoxy or similar. Steel to polyethylene, polypropylene, PVC, etc. would be weak in any case. I'd probably use a fastener instead of glue. Steel to CRE or GRE would be of more interesting because 1) the material is more or less like steel in terms of stiffness and strength and 2) they glue better.

Can you test how even you have to mix the resen and hardner, like do a 50:50 mix and 25:75 and 75:25

[@ProjectFarm]

Noah, thank you for this idea!

[@actionmedia4all]

That is a stupid question. Epoxy can not be mixed in different ways. It is not like polyester where you can play with more ore less hardner. There is only one correct way to mix. In laminating epoxy's a diversion of 1% can already weaken the epoxy by 50%.

[@rootvalue]

actionmedia4all Hey big boy, just a reminder that even though you’re on the internet and anonymous, you should still attempt to avoid making an ass out of yourself. It sounds like you’re a rational dude. You claim it’s a stupid question to want scientific, empirical evidence on a de facto rule but in the same breath claim to have those exact data. Discounting heuristics because you hold the key of knowledge is like burning your own ship. Where did you get your numbers from? Have these “magic ratio” experiments been performed prior? Were folks who conducted the test stupid for having a hypothesis, too? Whose proprietary epoxy and hardener formula was being tested, and which manufacturing batch? I’m sure it’s 100% exact between every single manufacturer since the history of time. You say so! Have you verified the results yourself? What’s your relative standard deviation? You sure are helping the scientific community. Are you by your own logic stupid for not proactively knowing the answer to the experiment of the video you are watching?

[@actionmedia4all]

wow, Hakeem, What a harsh reaction to my statement. First of all, I am not anonymous on the internet, far from that. Google me and you will know who I am. By the way, I did not make an ass out of myself and yes am a big guy. Second of all, I only have 30 years of experience working with epoxy building Windsurfing boards and now Windsurfing Fins in Carbon Fiber. So I know what I am talking about. My statement is 100% correct. In this time period where you can have acces to Google, asking a question that you could have answerd yourself in 20 seceonds (by googeling it) is in my opinion a stupid question. The first thing a teacher teaches you in school is to think first and try to find the answer yourself befor you ask a question. Every epoxy has his own exact mixing ratio based on the chemical composition it is made of. Not following the mixing ratio of the manufacturer is not smart. For every epoxy there is a datasheet where you can exactly see what propertys are of that epoxy, for curing times, curing temperatures and mixing ratio. That is where I get my info, and the 30 year experience. Fore more information here are a view links to what epoxy manufacturers have to say about it. www.westsystem.com/instruction-2/epoxy-basics/dispensing-mixing/ www.resinlab.com/images/resources/pdf/EpoxyMixingInstructions.pdf www.r-g.de/wiki/Fehler/Ursache/Abhilfe
