Safe MIL-M-24041 Polyurethane
(OP)
Are there any relatively safe polyurethanes available without MbOCA, TDI, or isocyanates? Are there any other compounds that pass the requirements of MIL-M-24041 that aren't polyurethanes? Perhaps a two part silicone.

I haven't gotten a response that that addresses the MbOCA and TDI concerns.

There are 1-part moisture-cure urethanes available, not sure if they don't still contain TDI?
Finally, be careful if you end up using silicone. Some grades give off acetic acid (vinegar) during cure, which can attack/corrode some electronics and circuit boards. There are types/grades made specifically for electronics potting, which evolve (typically) ammonia, which is less corrosive to metals and evaporates/dissipates more quickly.

Thanks

Several years ago they were still the market leader technically, but I don't know if they have restructured and divested their interests, but they must be worth a call.
