Maybe someone on here is a body man with the answer. Is there any auto body filler currently available that does not include talc for the filler portion?

I've googled and searched the web and every product that I've found mentioned in a thread that uses microspheres instead of talc still contains 20-50% talc when I look at the SDS.

I've looked at Evercoat light weight and Everglass, USC Duraglass, and even some of the metal fillers and they still show talc in the ingredients.

Lead?
No Talc in lead.
Not very easy to work with though.

I'm not talented enough for lead ... yet. Lol

i use this at the bodyshop i work in.

Why the concern about talc?

Being Woke I guess. Don't want to be sued like J&J Powder is.

Talc is pretty good at attracting moisture; maybe that's the basis for the OP's question ?
If you want no talc, you're looking at something like the reinforced filler, aka "kitty hair".
Sands like concrete in comparison, but doesn't suffer moisture contamination.
In a proper environment & with proper procedures, moisture contamination isn't really a problem.

a buddy and i were at the auto auction back in my junkyard days, looking at a car to possibly buy, when an old guy popped his head between ours.
not looking at either of us, he exclaimed : "cars with Bondo are NOT safe !" .................
my buddy and i looked at each other, then looked at the old guy, and he was gone !
we looked for him during the auction, and couldn't find him.
for a couple of years after, we looked for that guy so we could ask him to explain the statement to us. we never saw him again...................
so my friend, my advice to you is : "CARS WITH BONDO ARE NOT SAFE !"...................

Have you ever met 'that one guy' at a car show? Starts talking about camshaft specifications or whatever & just will not go away or shut up?

Talc, talc, talc - - that guy?

Set him to 'avoid' at all costs.

Hey thanks, I didn't see that one before! Does not appear to contain talc.

Talc is mined from the ground and the mineral deposits are found in the same veins as asbestos so it's likely to contain asbestos and not necessarily the least harmful type of asbestos.

Prefer not to lay down asbestos dust all over the shop sanding.

I looked at the SDS for Evercoat Rage and it had the following:

Talc (hydrous magnesium silicate) 14807-96-6

TWA: 2 mg/m3 particulate matter
containing no asbestos and <1%
crystalline silica, respirable
particulate matter

So Evercoat is claiming the talc in their product contains no asbestos. But the rest of the SDS? Wow. Makes you want to go back to lead.

I was willing to put up with the other chemicals as I mainly wanted to avoid the possibility of asbestos in dust all over the shop but looks like even the new generation fillers still contain some percentage of talc.
According to the verbage from bodyshopbusiness.com website:

"Talc — The original body fillers that replaced lead are filled with talc. Talc is hard clay that often has a fancy name like “magnesium silicate” but is really just mined out of the earth. Filler with talc isn’t waterproof because the talc wicks the moisture right through the repair. You know this is true because every time it rains, the water on your lawn is absorbed into the earth by the clay in the soil. If talc were waterproof, your front yard would be under water every time it rained.
Aluminum or fiberglass — Moisture-resistant fillers use aluminum or fiberglass as fill material. Neither will absorb moisture like talc does.
Mixing long strands of fiberglass into the polyester resin makes waterproof filler that’s also very strong. Why? Because the strands of fiberglass cross each other at every possible angle. However, it’s difficult to sand the very hairy filler to a smooth surface.

Using chopped-up fiberglass as fill makes for a non-talc filler that’s much easier to work with than the long stuff and is still waterproof.

Finely ground aluminum body filler is not only waterproof, but also spreads easily and gets so hard you can drill and tap it. So why doesn’t everyone use aluminum-filled body filler? Have you priced a can lately?

Plastic — Then there’s lightweight body fillers, which use microspheres as filler. Unlike pieces of talc — which are not only surrounded by the polyester resin but also absorb it — microspheres are surrounded by resin but don’t absorb any. As their name indicates, microspheres are tiny globes of plastic. Available in several sizes, they reduce the weight of the filler and speed the cure time.
Since they’re hollow plastic and won’t absorb any resin, they weigh less than a resin-soaked chunk of clay. And since they’re only surrounded by resin, there’s less resin mass for the hardener to catalyze so lightweight fillers harden faster. Because most lightweights also contain some talc, they’re not waterproof."
