I've been cited for excessive glue knowledge. Anyway, the Plastic to Plastic doesn't even mention the difficulties of gluing Polypropylene (PP) to itself. You'll be stuck looking up Amazon reviews to confirm what works and what doesn't

Glue of the month hasn't been updated since 2003. I know how to glue Expanded Polypropylene (EPP) to itself. Use E6000, which used to be called GOOP. It's a room temperature vulcanizing rubber cement that adheres well and will stay flexible once set. Also, 3M90 spray adhesive works well on EPP if you have a large contact area to deal with.

E6000 is the answer to a lot of jobs. Stuff is magic.

And it's cheap and readily available, which is awesome. Not to sound like a shill, I've just repaired an ipad case with it recently and I'm very impressed.

It really is fantastic for a lot of use cases. Superglue and epoxy are also mainstays, but they tend to be brittle. All have their place.

Yeah, the shear strength of super glue just isn't great if you're trying to fix things (like the hinge flap of iPad case) that gets repetitive use. However, scoring/sanding + super glue THEN epoxy or cement can help when joining smooth surfaces together. Also it's great for holding shit together while you wait for the other glue to cure

Yeah that was my first thought too. Former mechanical engineer. Immediately thought back to all the headaches trying to fix broken prototypes and thought this would be amazing if it had cross compatibility for PP, PE, nylon, ABS, silicone.

Still a cool concept. And if you’re in the plastics world you probably know enough through experience. But some hobbyists are going to run into some trouble treating all plastic the same lol.

As a hobbiyst, my last resort is usually Araldite (epoxy based 2 component glue). Hasn't failed me yet

Oof, I feel this, i once spent several hours googling how to glue neoprene to... some other kind of plastic I don't recall at the moment. I never found the answer but my first try (epoxy) did work.

When I need to glue difficult plastics, or anything else unusual, I'll start by browsing through the McMaster adhesives section. They have filters for materials – including HDPE, polystyrene, PTFE – so it's easy to find a glue that should work. They list brand and model # so I'll track down spec sheets or instructions from the manufacturer, or see if someone's put up a review on YouTube.

Yeah this site isn't great. Project Farm on Youtube did a great video about gluing ceramics with epoxy. at one point in the video he thinks he's got a glue failure, turns out the tile broke but the epoxy held.

How would you glue nylon to nylon? We were making 2 part nylon handles for a hand held probe, where one part fit inside the other. Couldn't get anything to work, tried super glue, epoxy, some special 3m glue I can't remember the name of that the machining shop recommended... None of it held up in the field.

Ended up drilling and pinning them.

Artootietoo t1_j06fwvq wrote

I would try e6000. I've used it to glue nylon to steel and whatever's on the back of a mirror. It's pretty goopy; you probably need a groove/recess so it doesn't squish out.

The parts I've used it on were 3d printed, so they had a slight texture which probably helped.

dayglo_nightlight t1_j07ozkc wrote

I sand and score smooth surfaces before trying to glue them to give the glue more to grab on to.

Grahamshabam t1_j08uui3 wrote

shortest answer is you don’t glue nylon

long answer is go to the 3M/Bostick/Sika website and use their tools to find a solution that ends up only being sold in 50 gallon drums to specialized industries

Yeah, I'd hope they'd put a subcategory for all of the various types of plastics

Why is a silly little website about glue one of the best things the has been linked in this sub? This is fantastic and genuinely helpful. It's this kind of specialized knowledge that really amazes me.

Brilliant idea. Saved link to Instapaper and bookmarked.

Will this be updated and/or expanded for more details? I'm thinking especially for plastic to plastic, as there's so many kinds and not all will work with the same glues.

What is insta paper?

Rich_Acanthisitta_70 t1_j071tnr wrote

It's a great app I picked up a couple years ago.

Anytime you're online, no matter what you're doing, if you see a story or picture, or comment, or video, or anything else that interests you and you'd like to look at it later or keep it for any reason, you just click the share icon that's on pretty much everything, and it keeps it all in one place organized by folders you label yourself.

Mine are like "helpful", "movies", "things I want to buy", "tech stories", etc. Just whatever articles or videos or links you're interested in or want to keep for whatever reason.

Another thing I like about it is that it strips out ads and popups so you can just see what you want to read or watch.

The basic version is free and is really all you'll probably need.

Aurum555 t1_j07ix0u wrote

This is exactly what I needed thank you so much. I have so many saved folders across different apps etc and being able to organize them all in one place is going to be amazing.

Rich_Acanthisitta_70 t1_j095goz wrote

So glad to hear that!

Btw, in case you've looked at other similar apps, I did try Pocket for awhile, but found Instapaper to be way more streamlined and easy to use.

Really glad this will help! Cheers😊

“We won't ask why you would want to glue ceramic and leather together - we just give gluing info. If the leather is thick (eg. boot leather), we recommend:

Household Goop But if it is a light chamois or suede, then go with: 3M 77”

This is great! but would be even more helpful if they linked directly to a product page instead of just the corporate site. They could probably earn a fair bit from affiliate marketing as well.
