Hi All,
Has anyone attempted to use good old fashioned hot melt glue as an
encapsulant for modules ?
Probably needs melting in a pot over a flame (with appropriate care).
A mould could me made out of Plexiglass with appropriate draft (angles)
and high temperature release agent.
A second thought is to use standard two part fiberglass mix, obviously a
lot more rigid, but potting boxes are likely to be needed also.
I guess I could use thin walled pipe to house a long rectifier stack and
associated capacitors.
Both of these options seem significantly less expensive than standard
epoxy potting compound...
Any thoughts ?

Im suprised nobody has bothered to ask this....
What is the potting being used for? Moisture, vibration, HV isolation ??
Depending on the use, the 'good enough' alternative might vary
considerably.
