MAX MCR Electronic Grade Epoxy Potting Compound for Printed Circuit Boards, Electronic Encapsulation, Waterproofing, Permanent Circuit Masking, None Conductive Epoxy Resin, DC/AC Up to 500 Volts

Very happy with this purchase. I potted 8 high voltage resistor assemblies and they all turned out great. Well, one leaked around the wire, but that was my fault. Very, very few bubbles. Did not have to use my vacuum chamber. It really does take about 24 hours for a full cure.

Great potting but be aware that is very thin. If you have any exit holes make sure they are well sealed as this is almost as thin as water, which is great for getting in and around electronics and avoiding air pockets but not great if you have opening where gravity can help it leak. In my case a little silicon around where a wire left the case to seal it up before using this and things worked great.

I use it to pot electronics; it does a good job. My first attempt never set. Second attempt I removed from mold after 24 hour cure, deformed, but cured 10 hours later. Third attempt poured hardener into mixing cup, add half resin, stir until smooth, add last half resin... MIX! Let set 48 hours == SUCCESS!

Stuff works great. Set up right as I was done getting it everywhere it needed to go and no arcs of electricity shooting everywhere since. I mean it's hard to wax poetic on this stuff. It works.

Works exactly as described. I used it on the computers on my deisel pickup. Worked great I have been using it on older modules for some of my older vehicles and it is a great way to protect older computers that don't seal well.

TOP QUALITY PRODUCT WILL BUY AGAIN

Follow the instructions closely regarding the mixing of the 2 parts, then double the effort. On my first use, I did not get it mixed good enough and ended up with areas that did not harden; even after a week the areas were tacky. I ended up using a simple clear 5 minute epoxy to cover the tacky areas and hide the imperfections. It looks to take much more effort at mixing that the normal 2 part clear epoxy. Next use I will be much more careful at the mixing process.

Great quality product, I like that it included the warning tag for people who don't know to check for crystalization. . . Product is more expensive on here (about $8 more,but I'm guessing the shipping was faster than ups ground)

Very nice product, Recommended!

Not sure what to say about this stuff. Mixed up a batch and it didn’t setup properly. It could have been because I didn’t accurately measure my parts but also not sure if I maybe got a bad batch?
