MG Chemicals - 8329TFF-25ML 8329TFF Thermally Conductive Adhesive - Fast Cure Epoxy, 25 mL Dual Dispenser

I needed to repair a failed Electrical connection where the supply wire attaches to the rear hinged window defrost heating elements of my Suburban vehicle. I cleaned both surfaces of the failed connection by repeatedly scratching the very rough surface ( didn't want to change the shape). I checked the fit, mixed the conductive epoxy, applied it to both surfaces sparingly, fit the pieces together, and held in place with some strong clear tape. It was a hot sunny day so I parked where the sun could shine directly on the repair and waited. The temp of the glass was near 120 so no need to use the heat gun for curing. The connection is strong and very importantly conductive to electricity. The defroster grid works great! I skipped the risk of breaking the window due to the heat of soldering the connection. This is definitely a win as repairs go.

The MG Chemicals 8329TFF Thermally Conductive Adhesive (25 mL Dual Dispenser) is a solid choice for projects that need a reliable thermal bond between components. I’ve used it to secure heat sinks, and it performs very well — creating a strong bond with good thermal conductivity.The main thing to note is that this epoxy cures fast. That’s a benefit for quick projects, but it doesn’t leave much working time. You need to plan ahead, have everything aligned, and apply it quickly before it starts setting. Once cured, it holds up great and transfers heat efficiently.✅ Pros:Strong thermal conductivity for effective heat transferCreates a durable and lasting bondConvenient dual dispenser for even mixingFast cure time saves waiting around❌ Cons:Very short working time — not forgiving if you need adjustmentsBest for small, quick projects rather than complex assemblies💡 Tips:Prep everything first (clean surfaces, position parts) before mixing — the clock starts ticking right away.Apply in small amounts for best bonding and thermal transfer.Wear gloves and work in a ventilated area — epoxy can be messy if rushed.If you’re new to thermal adhesives, practice with a tiny amount before applying to your final project.Bottom Line:The 8329TFF Thermally Conductive Adhesive is excellent for fast, secure thermal bonding. Just be ready to work quickly, because once it starts curing, there’s no going back

Works well, my use case was attaching a couple low voltage mosfets to a large aluminium heat sink, for a home made 12V 3 color led controller. good heat transfer and worked as advertised for electrical insulation. one thing to note is to always check as your applying that the heatsink has NOT pushed the adhesive away and you are not making a metal to metal connection. overall very impressed.

Sadly, bought this needing to repair rear defrosters on my car before inspection for sale.After opening, realized I couldn't squeeze any out so I resorted to trying a sledgehammer, then something sharp to try and break through first layer, closest to the opening. Nothing worked. One side was completely dried, solid and wouldn't dispense anything. The liquid bit came out of the single side, wasn't adhesive, making the product unusable. Terrible quality control!

There are better options out there. Pricey for what you get. And it didn’t last long after the first application they dried up.

I used this product to bond some a heat sink to the video transmitter on my drone. The bond set in no time and has held up very well. Product was very easy to use, definitely recommend.

Performs well in the application, but it wasn't workable after about 30 seconds. I suspect I got an old tube and the age was causing it to cure incorrectly. I would definitely use 8329TFS, the more flowable variant next time.

I used this product to fix my rear window defogger to attach the metal clip to the metal window placing. I don’t know how to solder so I used it instead. Current passes as it should. Make sure you use it on a warm day to cure properly
