Five Stars! Recommended!!

Reviewed in the United States 🇺🇸 on March 22, 2016

Size: 15 fl. oz KitVerified Purchase

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!

Fantastic!

Reviewed in the United States 🇺🇸 on April 18, 2019

Size: 15 fl. oz KitVerified Purchase

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!

ok but I have limited experience comparing it to other solutions.

Reviewed in the United States 🇺🇸 on October 2, 2016

Size: 57 fl. oz KitVerified Purchase

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.

I am very happy with the results

Reviewed in the United States 🇺🇸 on October 21, 2015

Size: 15 fl. oz KitVerified Purchase

For those who don't know what this is, this is a potting compound, In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents. Many people use this for various applications, but the most common is using it to seal OEM or aftermarket HID ballasts. This will make the ballast weatherproof and very resistant to shocks and vibrations that your car produces while driving. This kit includes enough epoxy to do 4 HID ballasts. Just follow the directions on the packaging. I needed to rush mine so I placed it in the oven at 125 degrees for 2 hours and I it was solid as a rock. I am very happy with the results. MG is the only brand I recommend, and Amazon has the best pricing for this set.

There is a lot better on the market, but a usable budget option

Reviewed in the United States 🇺🇸 on September 30, 2020

Size: 15 fl. oz KitVerified Purchase

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.

ridiculous pot life

Reviewed in the United States 🇺🇸 on August 21, 2018

Size: 15 fl. oz KitVerified Purchase

They're not kidding when they say it takes 4 days at room temperature for this epoxy to cure. It takes at least that long. I can't imagine a product that would need / want that kind of pot life.

If you don't plan on putting this in an oven to accelerate the cure, consider other options like MG Chemicals 834HTC which has a 24 hour room temperature cure time (haven't tried it myself, but the spec looks much better).

I don't know if its good

Reviewed in the United States 🇺🇸 on August 7, 2019

Size: 15 fl. oz KitVerified Purchase

What I do know is proportion exactly as they say or you end up with a never -curing goo thats messy and ineffective. Precise mix required....I think that was the problem. But when they give instructions, they should demonstrate or describe the importance of what exactly happens when precise measurements are not applied......point out the good the bad the ugly outcomes for people like me

Very slow cure

Reviewed in the United States 🇺🇸 on December 19, 2015

Size: 15 fl. oz KitVerified Purchase

Works as described; but if you are looking for some "5 minute" epoxy; keep looking.
This stuff takes 4 days to cure at room temperature. or 2hours at 65C.
It works for most of my uses; as I have a temperature controlled heat skillet that I use for solder reflow.

Just keep in mind this stuff as a VERY LONG pot life.

Bottles not full

Reviewed in Canada 🇨🇦 on March 21, 2021

Size: 15 fl. oz KitVerified Purchase

This epoxy is supposed to be mixed 50/50 by volume, however, there were unequal amounts of the two parts. One bottle was less than 3/4 full while the other less than 2/3 full. Also, one part had a solid scum just under the bottle cap that had to be cut and scraped off to get at the liquid below. I would expect more given the high cost of this small quantity of epoxy!

Nice product overall

Reviewed in Canada 🇨🇦 on November 6, 2014

Size: 15 fl. oz KitVerified Purchase

Nice product overall! I think the batch I got may have been a little old as some of the hardener had settled solid at the bottom. Had to use a screwdriver to stir it as the popsicle spatula just didn't cut it.

For best performance, they recommend heating curing @ 65C/149F for 2hrs once poured... If you don't want to subject the component to heat, what I do is heat up mix for a few minutes just before pouring. It flows very nicely and minimizes bubbles.
