Sorry for the delay, everyone. This is a long text. I have more context before choosing the best answer : "Appliquer le filet d’époxy entre la batterie et l’hybride sur une longueur de filet d’au moins deux fois la longueur du B+ (5mm),". This is worth waiting for. Thanks beforehand.

I find that thin indicates a bead, rather than a stream. However, the most important distinction is, surely, movement. A bead once run, laid or whatever is more or less stationary. "Stream" indicates continuous flow. Hooksett's examples, which translate "filet" variously as "trickle", "stream" and "shaft", demonstrate that it all depends upon rather more context than we have been given here.

un filet de : un filet d'eau a trickle of water
un filet d'air a (light) stream of air
un filet de lumière a (thin) shaft of light

which gives me the impression more of stream, than bead. My opinion, for what it is worth.

"stream of epoxy" gets 1 UK and 116,000 global ghits. "bead of epoxy" gets 355 UK and 44,800 global ghits. However "stream" is clearly not describing the same thing and I think that the Asker may need to provide more context. As hooksett notes, the consistency of the epoxy is a factor in whether or not it should be described as a bead, as is the size of the "filet".

There are as many google hits for stream of epoxy as for bead. See:

In my experience, bead is used more for stiff glues, or even "bead of caulk."
