## Description

Silver Conductive Epoxy Adhesive 8331D is an electrically conductive, silver-filled 2-part epoxy adhesive. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates. This product allows for quick, cold-soldering repairs. It can also be used as a solder replacement for bonding heat-sensitive electronic components, or for making conductive connections where soldering is not an option, such as when bonding to glass, soft metals, or plastics. 8331D has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330D. For a longer working time, time, use 8331S. Application Instructions: Read the product SDS and Application Guide for more detailed instructions before using this product (downloadable from MG Chemicals). Recommended Preparation: Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues. Syringe 1. Twist and remove the cap from the syringe. Do not discard cap. 2. Measure 1 part by volume of A. 3. Measure 1 part by volume of B. 4. Dispense material on a mixing surface or container, and thoroughly mix parts A and B together. 5. To stop the flow, pull back on the plunger. 6. Clean nozzle to prevent contamination and material buildup. 7. Replace the cap on the syringe. Cure Instructions: Allow to cure at room temperature for 6 hours, or cure the adhesive in an oven at one of these time/temperature options: 10 min @ 65 ˚C 5 min @ 80 ˚C Storage and Handling: Store between 16 and 27 ˚C in a dry area, away from sunlight (see SDS). To maximize shelf life, recap product firmly when not in use.

## Questions & Answers

**Q: Anyone know exactly how conductive this stuff is? Resistivity value?**
A: It's volume resistivity is .0004 ohm-m when cured properly according to the manufacturer.

**Q: Can you solder to this epoxy when fully cured?**
A: You should solder first, and then coat with conductive epoxy and cure.  The epoxy typically improves the electric contact accomplished by soldering.  Good luck!

**Q: will a fresh mix of this epoxy bond to the cured epoxy?**
A: I do not know.  After a careful reading of the warnings and dangers of this product I put it on the shelf unused.  I learned how to solder.  Just saying.

**Q: Does this stuff ever harden or is it always soft?**
A: The stuff hardens in about 1 hour. It is dispensed from a hypodermic type dispenser and can be mixed with a kitchen knife or small spatula. Have some alcohol readily available to clean up your mixing and apply tool and possibly you. I found that it conducted current quite well. When you are mixing and using this product it reminds me of using bondo.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fixed my Defroster tab!
*by N***B on September 7, 2012*

I originally brought several defrost repair kits at my local Auto shop. Although they did work, they only lasted about a week or two before the tab ended up falling off again. I ended up searching the internet for alternatives other than buying a new back windshield. I tried conductive tape and liquid solder sold at lowes.. both didnt work at all. Finally gave into buying this, since the price was pretty expensive. Just wish I ran into this sooner instead of spending 40+ dollars on other alternatives. The epoxy when used correctly hardens like concrete while keeping electrical conductivity.Here is step by step on how I fixed my defrost tab on my 04 Toyota Solara.-Remove drivers side rear glass panel by using a panel popper.-Remove tab from wire.-Remove solder on bottom side of tab that will attach to window. I initially tried to use a solder gun but found using a drill gun with a wire brush attached 'sanded' the excess off with ease.-Clean tab and location on glass with rubbing alcohol. Make sure the new location is not the same one where the tab fell off.-Use a small vice grip to hold the tab. I found a great location where I was able to use the back seat top cushion to jam the vice grip to help hold the tab to the glass window. It was very sturdy.-Grab a piece of cardboard and a stir stick. Squeeze out epoxys at a 1 to 1 ratio(1 black tube 1 white tube), I only ended up using maybe 1/4 of the tube. Stir very well. It will take a while for the epoxy to harden, so no need to rush.-Use stir stick to generously apply the mix to the tab. (I put a small amount on the bottom) Make sure you spread it around to contact the circuit on the glass.-Use a hair dryer to help harden the epoxy. Very important: Dont mess with it while it is drying! I propped up a hair dryer and set it to low heat since it was only about 6 inches away from the tab. Left it on for 20 min. Came back and the epoxy had hardened.-Remove vice grip and reattach wire to tab-Test with multimeter before reattaching panel.Enjoy your great work!

### ⭐⭐⭐⭐⭐ Silver Epoxy instead of soldering for connecting replacement battery of a Norelco shaver
*by A***G on October 27, 2021*

Silver epoxy made battery replacement for a Norelco shaver a cinch, without need for soldering equipment, but you may need a heat gun to fast-cure the epoxy. I saved my shaver from the landfill.Norelco shavers are not manufactured with battery replacement in mind. Replacement requires desoldering the old battery and re-soldering on a new replacement battery. The factory solder is located in the hidden back side of the circuit board, and not easily accessible. Flipping the circuit board over to reach these soldering locations can easily damage the delicate copper foil electrical connections coming off the circuit board. Besides, to solder, you need soldering iron, flux, solder, desoldering pump, and probably magnifying glass with light.The general principle here is not to solder and not to disturb the circuit board at all. Cut old battery connectors at mid-length to remove the old battery. Use silver-epoxy to glue together the old connector stubs and the new battery connectors.Detailed steps are as follows:(1) Use a T7 Torx screwdriver to remove the two screws on the Norelco shaver’s back. Remove the back cover to expose the battery. No further disassembly is required.(2) Pull old battery part-way out of its plastic mount to expose the two flat connector strips, which are factory-soldered on the circuit board hidden under the battery mount.(3) Cut the old battery connector strips close to the body of the old battery, leaving the stubs long. These stubs will then be epoxied to corresponding connector strips from the new battery.(4) Measure and cut connector strips of the new battery to the appropriate length, leaving enough length for the new connectors to overlap the old connector stubs. Adjust and bend connectors as needed to ensure good contact before applying epoxy.(5) Mix epoxy in well-ventilated area. Wear gloves. I used less than 1/5 of the volume of epoxy supplied, totaling less than 1mL from each of the two syringes.(6) Use a needle or some other small narrow tool to apply silver epoxy to the old connector stubs first.(7) Snap new battery into plastic mount. Make sure new and old connectors overlap, with epoxy in between.(8) Apply more epoxy to envelop the overlapping battery connectors.(9) Make sure there is no epoxy bridge between the two poles. Any small trace of epoxy connecting the two will cause a short. This happened to me.(10) Use heat gun for 10 to 15 minutes to cure the silver epoxy. Official temperature for fast-curing is 90°C for 12 minutes, or 125°C (above water boiling temperature) for 7 minutes. Heat gun works best. Hair dryer on high may also work. I do not recommend baking the shaver in the even, risking damage to the electronic components and possibility of later food contamination. I turned my heat gun up to where it feels fairly hot to my hand at 12 inches, but short of burning myself.The actual battery swap should take no more than 30 minutes. However, it took me 3 to 4 hours to figure out how to do it with epoxy without extensive disassembly and without soldering.As of date of the original review, 10/27/2021, it is barely cost-effective to replace the Norelco battery, instead of buying a new shaver. In my case, silver epoxy costed $49, replacement battery $13, for a total of $62. A new waterproof wet-dry Norelco shaver costs around $130. A non-waterproof Norcelco can be as cheap as $30. Mine is a wet-dry waterproof one, so I saved around $68. Most of all, I prevented my 10 year old Norelco from going to the landfill.As of 01/27/2023, the shaver is working fine. Heat from charging and discharging the battery has not caused noticeable disintegration of the silver epoxy by inspection.

### ⭐⭐⭐⭐ A Solution To Many Problems
*by O***T on November 5, 2019*

So I chose the more expensive type with silver, and it is a very interesting product. Even though it is expensive, I recommend doing a "practice run" with some scrap materials to get an idea about the properties of this mix; I practiced and it still got sloppy. Also, use good ventilation; something in here got to me after only a few minutes. It is slow to mix, and tends to be lumpy, but I managed a very successful repair on a potentiometer so it was well worth the money. My biggest criticism is the texture/thickness. It is so thick it barely comes out of the syringe. The silver component in the other syringe is on the runny side. This combination makes mixing slower. All in all, this stuff can perform some miraculous repairs.
