MG Chemicals 832TC-450ML Thermally Conductive Epoxy Encapsulating and Potting Compound, 15 oz Kit, Black

Great product cures fairly quickly at room temperature. Epoxy wouldn't run after 5 hours. Just make sure to mix resin and hardener by volume and not by weight as their density is not the same, so no measuring scale for this one. Also mix part A and part B by itself before introducing them to each other, just make sure to use separate tools for each part (the .45 gallon kit comes in tin cans)

Mixed it per instructions. 7 days later and it's still tacky.

This is what was recommended to pot Denso slim HID ballasts to ensure they don't get affected by the weather/moisture.I had never done it before but watched a few videos and saw the review on here as well so I'm posting my pictures to add in the bunch.Very easy to do, make sure you're wearing gloves and mix small batches, that way you don't accidentally run out of time or it becomes too hard. I did one ballast per batch that I made.Slowly poured into the ballast and make sure there's no air bubbles and then you wait several days unless you put it in the oven to cure.I'm doing a projector retrofit on my CT 200h so I have no rush at all and let these cured for at least a week or so. You can see the finished product is a completely waterproof ballast.This does add a little bit of weight to the ballast I was actually sort of surprised at how much heavier the ballast weighed after potting them. This probably completely voids any manufacturer's warranty and of course if something goes wrong you're not going to be able to get into the ballast after this.But if you're potting them you probably already know that and it doesn't matter.

You wouldn't think it would but this stuff can wick up small holes in your connectors and rise up to fill the holes for the terminals --- and make the product you are trying to pot into a "brick" or "mechanical sample". Pretty much ruined my first batch of product. I don't know if this is because the 65C heat curing makes the product briefly more viscous, but I had to use hotmelt glue to fill in any crevices on stuff that absolutely needs to be protected. So I'll knock off a star for that.Also this larger size comes in cans paint cans, not bottles. Should come with two large syringes but it doesn't.however it is thermally conductive and resistively non-conductive so it does the job its intended for, just with cautions.

There are a lot better, more thermally conductive, faster curing, better fixed, and less smelly options on the market.Does it work? Yes.Is it worth the price? Barely.Willing to spend a bit more and get 2x or more performance with less fuss? Look at Kona 870 in dispenser tubes, or nearly anything else in mix pots, like Duralco 4525.

I've been using this for a while, but the latest shipment came in 1qt paint cans, not screw top bottles. How am I supposed to pour 100 grams of epoxy from a 1qt paint can and reseal it without making a complete mess. What were they thinking.

I was looking into weatherproofing my Denso HID ballasts and this Thermally Conductive Epoxy Encapsulating and Potting Compound form MG Chemicals was highly recommended multiple times on a big hid forum (hid planet) so I decided that I had to go with this option. I've had no previous experience with weatherproofing HID ballasts in the past but this kit from MG Chemicals made it a complete breeze. Honestly, it was way way way easier to use than I thought it was going to be (make sure you just follow the simple instructions that are included… it's really THAT simple to do). Don't forget to make sure you wait long enough to let the epoxy dry completely; it does take a bit of time to fully dry! Thought I would also throw this in here even though it seems fairly obvious; but as with anything in this nature, DON'T spill this epoxy on anything that you really like or want to keep. If you wind up spilling it on something, it will most likely not fair well for that item. Anyhow, this Thermally Conductive Epoxy Encapsulating and Potting Compound form MG Chemicals worked wonders and is doing an amazing job keeping my denso HID ballasts sealed. It has been going on 3 years strong now since I've used this kit to seal them up! From my own experience, this kit has enough epoxy in it to seal up 4 denso ballasts (that's 2 sets). All in all, I would highly recommended this product to anyone looking to weatherproof his or her HID ballasts!

Used this to pot some Denso HID ballasts. Used about 30ml of each part, so 60ml total, for each ballast.I followed the directions pretty closely. Started off by pouring each part into their clear measuring cups. Then poured them into paper coffee cups to mix and let settle for 30 mins. This allows air bubbles to escape to the top. Then I slowly and carefully poured the epoxy into the ballasts and kept going back to areas to pop the bubbles and add more as needed as it sat. Process took about 30+ mins per ballast because I was watching and waiting for bubbles to appear.Curing time is a bit crazy at room temperature, 96 hours. Luckily I am in no rush and they have 48 hours left at the time of this review. They are pretty rock solid as is now though, a few tiny softer spots if anything.I wish the price was cheaper but you do get what you pay for. I know these Denso ballasts should last a very long time, especially with this epoxy. I have plenty to do more, so I may venture out and do that, then resell those. I highly recommend this stuff!
