Is Sylcap 284 as permeable as Sylgard 184?

[FirkwithaD]

I just need a permeable PDMS material. Sylgard comes in MOQ 0.5kg, while Sylcap is MOQ 100g which is better, I just need to know if it will work the same.

Ask the manufacturer(s).

Sylcap is reported to cure faster than Sylgard l, so that’s a difference.
