Hi,
I use PDMS (Sylgard 184) to make Micropillars. In order to make them more flexible, I need to reduce the elatic moduli of the meterial.
I see from this paper(see attachment): Mechanical properties of silicones for MEMS (F. Schneider et al), that they added a thinner to their PDMS products (both RTV 615 and Sylgard 184), and the cured silicone with added thinner has a lower elatic moduli. However they didn't mention exactly which thinner they used in their application.
I read from the document of Sylgard 182 that the Dow Corning 200 Fluid 20 cS can be added for lowering the viscosity. However I don't see such description in the document of Sylgard 184, and I'm wondering if this fluid can also be applied to Sylgard 184 for the same use (I already contacted Dow Corning, however till now nobody answers...So I think perhaps I can first look for some help here). Also, can it be applied to Sylgard 186?
Or do you have any other suggestions concerning the thinner for Sylgard 184?
Thank you in advance!
