Epoxyseal 9000 Electronic Grade Potting Epoxy, Epoxy Resin PCB Coating, Electronic Potting Epoxy, Casting Epoxy - 48oz KIT.

I'm so happy to have discovered this company. The potting compound is so simple to use and the results honestly speak for themselves. The price was ultra-competitive and the quality was dead-on wonderful. The resin mixes quite easily, pours very smoothly and proved easy to work with. I didn't de-gas in a vacuum chamber as this was for circuit board potting and even without de-gassing, the air bubbles cleared themselves up quite quickly. Great product, arrived the following day, I simply couldn't ask for more. Thanks so much!

Refurbishing an electric clutch on a vintage John Deere garden tractor. The windings were good, tested in spec. Needed a new binder/ winding protector and this product fit the bill. Poured with just the right viscosity giving ample time to do a neat job. A touch of flame from a torch lighter and any surface bubbles disappeared leaving a smooth and shinny surface. Glad I found this. Saved me hundreds of dollars for a replacement.

I have an enclosure box with pricey electronics inside it that I have to keep outside. Because my area is prone to occasional rain and high humidity, those environmental factors were compromising my box's performance or make it not function at all. On my first try I followed the instructions and mixed enough two part epoxy to fill the electronic box cavity near it's brim. The epoxy mixture hardened stiff solid inside the electronics box enclosure after just two hours of cure time. Now everything works fine, and I no longer have to worry about malfunctions on my circuit board due to moisture condensation. I am happy.

I measured out two parts of epoxy resin (larger bottle) and one part hardener by volume. It can also be measured by weight, according to the directions. Then I stirred it for 5 minutes and poured it in. It has the consistency of maple syrup. Be advised that if there are any holes or gaps in your project, this stuff will flow through them, so they need to be plugged first with something like hot glue or silicone. Depending on ambient temperature and humidity, it should cure in about 24 hours. I used it indoors, and it was hard as a rock overnight. This was designed for "potting" electronic components to protect them from moisture and shock, but it can also be used for other repairs requiring the strength and durability of epoxy. I suppose it could be used as just a glue, but you'd have to keep it from running somehow while it was curing. After curing, it is black in color. All in all, this is great stuff that is very useful for certain projects where runoff during curing isn't a problem.

It might work well but it’s too runny for my application. I tried to use it for waterproofing electronics as they passed through a waterproof case. But it was so runny it leaked around the rubber gaskets and out of the case. It’s still the consistency of maple syrup an hour later. I wouldn’t say this dries fast at all.

Works well good buy

One of the best products I have used to seal and create watertight electrical connections. On my applications, it seems it takes about a hour to set, and around 24 hours to cure.

Generally, the product works as described. However, I now can only use it for projects that dissipate very little heat, as the manufacturer confirmed they do not know, nor did they test for, thermal conductivity. This should be considered a standard test for any electronic potting compound. Even if the conductivity is very low, that is fine, but at a minimum you should have the value available as part of the product's specification.
