Looking for Epoxy to protect smd components

[Rogelio]

Can you suggest an epoxy to protect my small pcb w/ smd ic and components 1 1/2" X 1".
I need epoxy that hard enough to hide secret components can not be easily copied.

@Chartal

Many Thanks for the info.

Even when potted, things can be reversed engineered, it just takes a bit more care and time.

Grind off the part numbers before you encapsulate.
