## Description

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: desertcart.com: Industrial & Scientific

Review: Great stuff. Works exactly as advertised. - 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.
Review: Works well - 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.

### ⭐⭐⭐ MIX,MIx,Mix,mix.... mix
*by B***N on March 2, 2024*

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!
