Review: A good alternative to Sylgard PDMS - We are using this in our laboratory for casting microfluidic devices and have found it to be a good alternative to Sylgard-184, as it has similar mechanical & optical properties, does cure relatively quickly, and can be plasma oxidized to seal with glass surfaces.
