I have used Sylgard 184 and 182 with good results. This is with storing resin in the vat, no water on PDMS and no alcohol on PDMS.
Agree, I also use Sylgard 184 and keep the resin (overnight) in the vat. Also NO water and NO alcohol come into contact with the PDMS. So far this seems to be my 'preferred' brand/type for PDMS. BTW, I have 3 vat's that I use concurrently. Always making sure I have a 'fresh' one(or two) available when needed. Loosing a 'day' because of not having a fresh vat available would be a 'problem' and a missed 'return on investment' taking that the cost of a 'fresh vat' is about USD $5 on Sylgard PDMS used.
Its just that being in Europe you have to keep 'an eye' on the Sylgard stock as ordering it through eBay still takes about a week to max 10 calendar days before being delivered in Europe.
