[mems-talk] pdms base/curing agent ration

[Barbara Cortese]

even this paper can help:

Carrillo F, Gupta S, Balooch M, Marshall S J, Marshall G W, Pruitt L and Puttlitz C M "Nanoindentation of polydimethylsiloxane elastomers: effect of crosslinking, work of adhesion, and fluid environment on elastic modulus"
J. Mater. Res. 20.10: 2820-2830 (2005)

A 3:1 or 5:1 should do for you.
Otherwise try h-pdms.
