Electrically Conductive Epoxy, Silver Adhesive, Room Temperature Cure, Air Dry AA-Duct 902, 2.5gm kit (1) (One Pack)

While the minimum temperature stated in the sales page is 65 degrees C, the provided instructions say 65 degrees F. In my application, the mean temperature of the items being glued there was NO way to even have 65F through the 24+ hour desired cure time. So I called the 24 hr information number listed in the sales page and got one of the experts in the lab who answered the call, directly and quickly. While higher cure temps are desirable (when possible) the adhesive WILL cure at lower temps (he didn't give me an exact temp but said that our over night temps of ~ 50 degrees at this time would be okay.) He said give the glue at least 72 hours, undisturbed and don't let it get wet. Also, be SURE to mix the glue per the instructions which was VERY easy with the packaging provided and it is also easy to apply by snipping a very small opening in the corner of the mix-package (the glue is a thin paste and flows well. Be SURE to mask anywhere you DON"T want the glue as it sticks very well to everything it touches but can be cleaned up after drying, by filing or sanding, if that works for your application. Also, since this is a paste, try to work it into the joint to FULL FILL the gap(s) for maximum strength and conduction. Realize that if electrical isolation is needed be sure to keep the adhesive from bridging any insulating aspects of the assembly because the glue will make a short of very low resistance. In my application and after waiting 4 days for the adhesive to cure, I used a file to shape any rough areas, cleaned everything up with alcohol, and it seems both strong and, certainly, conductive. While it seems expensive, the material is WELL worth the cost if the application is important or difficult to work around, otherwise. Try to estimate the amount you truly need as not having enough could prove problematic and having too much just wastes money.

Worked great to fix circuit board connection. Even for a person with no experience doing such things. Too bad it is only a 1 time use though.

Great repair kit

I bought this to build up a terminal on a fuse to be used with a worn vintage fuse holder that can't be readily replaced. Since it was the fuse's terminals that were to be built up standard solder wouldn't work in this application.The epoxy when mixed with the included hardener is slightly runnier than toothpaste and is extremely sticky, so care is needed during application.After 24 hours of curing it had thickened, but not by much. It was about the consistency of peanut butter.After 48 hours it was the consistency of a soft rubber eraser. It never got any harder.Bottom line, a waste of my effort, time, and money.Updated 10/08/2019:The vendor lists this product as, "Electrically Conductive Epoxy, Silver Adhesive, Room Temperature Cure, Air Dry AA-DUCT 902 , 2.5gm kit". The key part here being, "Room Temperature Cure".One week after application this product still had not cured and was the consistency of fresh window putty. From the other negative reviews on Amazon it was clear that I am not the only customer that had this problem. Several of them have mentioned needing to put the epoxy in an oven to get it to cure.So I set my oven to 200 degrees and popped a couple of items with the never curing epoxy on them into the oven and went about doing home repairs. After three hours I removed them and set them aside to cool down.I checked them once they had cooled and the epoxy had finally set. And the set epoxy was conductive as claimed.But 200 degrees fahrenheit is in no way, shape, or form "ROOM TEMPERATURE", as advertised.I will not mince words. This is FALSE AND MISLEADING ADVERTISING.

Most likely I used this for an application that isn’t the primary purpose for this product. I used this to re-attach the rear window defogger on my 2016 Jeep Wrangler. It takes time to cure and you need tape to hold in place. The rear window defogger now works again. I will update if this fix is durable.

This adhesive worked great for what I needed. I used it to attach wires to nickel plated neodymium magnets to make jumper wires. This way I could use a AA battery charger for C and D batteries.I would have preferred to use solder because it's easier to use and this paste is pretty expensive. But heat affects the strength of a magnet so this was the next best option.The description says that it cures in 5 minutes at 100 degrees Celcius (212 Fahrenheit). I preheated the oven to 200 degrees, applied the paste to the top of the magnet, pushed in the wire and added more adhesive on top of the wire, then put them in the oven. After 5 minutes the paste was still soft but noticeably harder. Put back in for 7 more minutes for a total of 12 minutes and this time the paste was hard when coming out. Let them cool for about 30 minutes and the paste was now as hard as actual solder.The adhesive seems to be strong, it holds fine when pulling the magnet off from the refrigerator while holding the wire.I checked the resistance from the magnet on one end of the wire to the magnet on the other end. There was almost no resistance and was the same as when checking the resistance from one side of a single magnet to the other side, so clearly it has excellent electrical conductivity.There was plenty of paste left over so I squeezed some out onto a piece of paper and left at room temperature for testing. The paste was completely dry and hard in about 8 hours.The paste is fairly thick which helps hold your work together if needed. Although it probably wouldn't be practical for precision work since it would be hard to control when squeezing it out of the packet.
