What are the most flexible/elastic resins for printers? Are there any easily accessible additives that could make standard resins more flexible? (programming.dev)

Title. I'm looking for resins with the lowest Shore hardness, the lowest one I've found (that I can buy on aliexpress) is Resione F39, with Shore 60-75A. Ideally, I'd want to get something closer to Shore 30-40A.

So, failing that, anyone with a higher understanding of chemistry can explain what additives are usually added, resulting in a cured resin with greater elasticity?

I've never needed release agent with platinum-cure silicone as it's not stuck to anything except itself unless it was porous. I have needed to lubricate bits of moulds that would have had too much of a vacuum if just pulled, though. Also, when I initially referred to coating the mould, I didn't mean a release agent but rather something like PMMA (acrylic) dissolved in acetone to protect the silicone from the resin as described here: https://blog.honzamrazek.cz/2022/07/preventing-platinum-cure-silicone-cure-inhibition-in-resin-printed-molds/
