What you want is called "potting compound" or "potting epoxy." It's usually black. Here's some cheap stuff in a small quantity: https://www.amazon.com/MG-Chemicals-832HD-Black-Encapsulating/dp/B073JNDRXJ/ref=sr_1_3?keywords=potting+epoxy&qid=1564158629&s=gateway&sr=8-3
They sell single-component potting epoxies that cure with heat or UV as well.
If we're not talking crazy stuff (in terms of heat, voltage, etc.), then regular old "five minute" epoxy from the hardware store will work fine. Just don't use JB weld or other "reinforced" epoxies, since the reinforcement media might be conductive. You can check the material datasheets to be sure - it usually contains info on heat resistance, dielectric properties, etc..
If you are working with high voltage and/or high-power stuff...well, you probably know what you're doing and don't need my help, haha.
Personally, I usually use this stuff. It's not even a true "epoxy", but it works fine for what I do: https://www.walmart.com/ip/Amazing-Goop-144100-Trim-Repair-Adhesive-1-fl-oz/

While I know it exists and the process I haven't tried enough types to have much of an opinion.
But this stuff works pretty good: https://www.amazon.com/dp/B073JNDRXJ/ref=cm_sw_r_cp_apa_i_R.7KDbW2FPV8T
