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!

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.

Used as a hermetic seal and protection of my intellectual property. Cures to a very smooth and shiny surface, solid as a rock. As far as I can tell, the electrical properties are good, though the circuit only operates to 200VDC.A few cautions: make sure you get the mix right. Use the clear cups with marked gradations to get an exact 2:1 ratio.Make sure you pour the clear hardener into the cup first, and add the black resin into the hardener.Mix, mix, mix, mix, mix. Did I mention mix?Instructions tell you to mix for 3-5 minutes, pour into another cup, and mix another 3-5 minutes. Don't be lazy, take the time and follow those instructions!!I use a bamboo skewer to mix, although I admit a tongue depressor would probably work better given the fatter profile.I have found optimal bubble avoidance by a short term heat gun many inches away after you have poured your amount - don't need to get the stuff hot, it will warm itself without much help. But a brief warmth period helps drive out any surface bubbles. Too many bubbles, you are mixing too aggressively.

I enjoy this product on my project. Worked great.

I liked how glossy, bubble free and solid this dries. Can be filed or sanded. I use it for far more than electronics encapsulation. Excellent epoxy all around. I asked company if I could apply 200 degree heat to speed up curing. They did not recommend this. I am doing it anyway and it appears to be just as good as the 24 hour cure. Takes about an hour, just put lamp on top of it. I can’t imagine any better performance with slow cure but again they do not recommend. Awesome product and way cheaper. Ships from manufacturer so you know your product is fresh and not jacked up from storage.

I bought this epoxy product to pot some electronics. WHAT a disappointment, it never hardened. Followed the instructions and was so surprised at the results. DON'T waste your time or money. What a junk product. I'm angry that I have to give it one star!

This is the best product for sealing electrical connections in wet environments. We use it for our underwater lights on flounder boat, and underwater dock lights. 👍👍

It worked and comes in very handy as I design some of my products. I'll order it again.
