excellent
This is an excellent product. The epoxy cures in about 60 minutes to a nice hard consistency and is very conductive. The small syringes dispense the epoxy very well. I have absolutely no complaints about this produce. That said... I usually just want to use a tiny amount at a time and it's a bit tricky to get a few drops of the A and B parts out of the syringes. I've found that if I twist the plungers as I apply a VERY SMALL amount of force, I can get the small amount out that I want. It'd be nice if this were easier, but I think this is a better solution than having an A and B bottle that I'd have to dip into, so I'm happy... but an easier way to dispense a drop or two would be nice. I haven't check to see if one of my needles can be screwed to the syringes...

Good working consisrency
Works well as a conductive filler and bonding agent for my sensor product. Solved three design issues; filler to smooth a rough edge, bonds two parts and electrically conductive. Paste consistency. Wear gloves. It’s very messy but cleans up with IPA before cure.

Good for rear window defogger, but use cooper foil as insurance
I used it to reattach the male electrical connector to a rear window defogger. I mixed properly, held it in place with a stick, and let cure for 65 minutes at room temperature per the instructions. However, some reviews said it cures better, and stronger, with moderate heat from a hair dryer or heat gun applied. I set a small portable office desk heater, 400W, about ten inches away for most of the 65 minutes drying time. I removed the stick and the connector was stuck to the metal strip on the defogger. I did not pull on it too hard to test it, because I was afraid it would come off. I did check the remaining epoxy in the mixing dish, and it did set up hard, but didn't seem to have a great bond between the wood mixing stick and the plastic I mixed it on. Not like JB Weld, but the stick and plastic tray were stuck together mildly. For extra measure of conductivity of the electric current to the window defogger grid, and to help hold the connector onto the window long-term, I covered it with electrically conductive copper tape, with adhesive on one side (some have adhesive on both sides). I found the tape on amazon as well.

It works as advertised. Not inexpensive, but easy to use and does the job.
Used this to reattach a defroster grid tab on 2004 Chevy Express. Works easily and created an electrically active and strong connection. Bright silver color.

Very expensive epoxy for very little volume!
This is a decent product, and if you really need it, then you won't care about the cost! But please note that the syringe is only 2 inches long---- a very small amount of epoxy ----NOT like the volume you are familiar with Loctite epoxies. So this is good, but VERY expensive for what you get. If you have a small circuit board application, then it's worth it, but if something bigger, then it's way too expensive to get just a few connections for $88. I wish there was a bulk product like this somewhere---- but NOT for hundreds of dollars!

Good conductive epoxy.
Reattached metal contact posts to the rear window circuit for the third brake light plug. It’s almost like a thick paint before it sets up. Working in a tight space might be messy unless you use something like a paint brush or toothpick to apply it. Sets up quickly in warm conditions.

Don’t waste your money on this product
Used it to glue the defogger connector to the back window of my car and it did not work. Tried it twice and both times it didn’t last more than a couple of days. Don’t waste your money on it, it does not work

This one works.
I bought the stuff in the auto parts store twice. They restuck my tab, but the defroster never worked. I bought this one, did not use a hair dryer and just let it dry overnight. I didn't even remove my non working tab from the other junk. I just smeared this overtop the tab, making sure the new stuff was contacting the grid. Works perfectly. Yes it's expensive, but not as much as me buying the other stuff twice to have neither attempt to work. This one works. There's enough here to do multiple jobs. Buy this one.

Didn't know this existed but I do now.. easy to use and is a really good conductor. I'm using for a serious precision job and having no problems at all.. shame it's so expensive but sometimes you only get what you pay for .. to be fair a little bit goes a long way. Love the stuff

Sono riuscito a riparlare lo sbrinatore del lunotto termico dell'auto, si era staccato lo spinotto del collegamento elettrico sul vetro. Vi consiglio: pulire bene con alcol, mettere un poco di colla sul vetro dove si è staccato, mettere un poco sullo spinotto e attaccare provvisoriamente con nastro di carta. fermo per un'ora.

Me funcionó excelente para arreglar un conector de mi auto

I used the products low resistance to fix a LFP battery terminal that broke off. Then I stabilized it more with another epoxy. The measured ressisance is almost zero.

This product works every time.. Great reliable material.
