Like all rubber cements, it's just rubber mixed with a volatile solvent. In this case, E6000 is SBR (styrene butadeine rubber) mixed with tetrachloroethylene. Nasty stuff, but then all rubber cements are dangerous to some extent. Be sure not to get it on your skin and when you do, rub it off and wash up with soap and water immediately.

I used this for a large project. So far, I've glued wood, fabric, metal, plastic and glass together. I roughed up the surfaces with sandpaper or a file or just a utility knife before applying the glue. I used the glue liberally, smearing it on as much surface area as possible. The excess that oozes out is easily wiped away. For the wood, metal and glass, I dipped a corner of a small rag in acetone and used it to clean up.

I used a clamp to put pressure on the two objects being bonded. For flat objects l used a stack of books. I left it under pressure for 24 hours in a 55 F degree room and it bonded well. I let it cure for a few days before testing the actual strength of the bond, which is impressive. The heaviest item I used this with is 11 ounces and it is held by a 1 x 3 inch Velcro strip between wood and plastic. If you consider the amount of pulling force each time I yank the Velcro apart (at least a few dozen times now), it's held up really well.

I bought the black version, which applies and dries pitch black. I have no experience with the clear and white one. I grabbed a few plastic butter knives from a certain large fast food chain and use that to apply the glue. If you do use something similar like Popsicle sticks, then twirl it around a bit like you might with spaghetti on a fork. The glue tends to string up a bit as it hits the air and gets pulled apart.

Generally, I prefer using a two part epoxy as they create stronger bonds, but this seems to work well enough for lighter weight items. That said, I did not use this on anything that flexes like clothing or on small items like rhinestones. I mostly glued LED light strips, battery packs, small solar panels, pieces of glass and tiles, cables and other things. If you're doing something similar, I recommend this as a viable alternative to an epoxy.

So far I have used this glue for my steampunk wedding bouquet which held my keys, buttons, and charms on very well. It does take time for the glue to dry and that is why this is best for heavy duty.
Shoes-I have used this glue to put 4MM rhinestones onto my heels and they have not fallen off yes. This is GREAT glue if you want to decorate shoes.
Clothes-Used this glue for clothe crafts and I have washed my projects multiple times and the stones still stick with this glue. This is also the best glue to use if you want to put rhinestones onto stockings and jeans.

To get the most out of this adhesive make sure you read the whole back side of the package. Use Vaseline on the cap threads/nozzle to keep it from gluing itself shut.

I use it for jewelry making/repair and it comes out in rather massive globs for that application, but I find sacrificing a sharpened pencil to the cause solves that problem very neatly. Whatever applicator you use in the event you need small, precise amounts, mind that the adhesive may leave trailing strings you'll want to address before they touch anything.
Mine was expired when it shipped so I was a little concerned about it drying out or being tacky but so far so good. I notice the packaging is VERY temperature sensitive, so, if it's hot outside and the cap is off, you're gonna get a lot of dripping adhesive as the heat makes everything expand.
I've repaired about a dozen pieces with this so far - from stud earrings to chunky necklaces. I've also fashioned 3 brand new pieces. The adhesive works great on cabochons, metal, sea glass, pottery - whatever you've got.
Again, read the directions carefully and in their entirety before you start.

DEFINITELY WORKS!!!!! I SHOULD HAVE USED SOME PLASTIC GLOVES BECAUSE THE GLUE IS VERY STICKY AND HARD TOO GET OFF YOUR FINGERS.

E6000 as amazing craft glue it really gets the job done that holds really well. I do find that it works better if you let it sit just a second before applying the stones. Or any other items that you're glueing together. This particular glue works really well with hard surfaces so you couldn't really use this on fabric because it doesn't hold well with the fabric. The only thing I don't like about 6,000 is the smell the smell is so loud. The toxins from the smell can sometimes be overwhelming so you really should use the fan when using the glue. Also be very careful and try not to get any glue on your hands or wash it off as soon as possible. I hope that my review was helpful .
