Hi

The chemicals will be mixed in Claudia's lab ( Los  Gatos research lab) and then brought to our lab. I have extensively talked to Dien and I will do so with Claudia.
Some of these chemicals on the smelly side.

We plan to spin-coat these silicones on 4 inch silicon wafers and plan to do this using the Headway manual coater and curing using the hotplates. I believe Dien (coral: adnguyen) has submitted the information for the OE4100 elastomer, but we would like to add a solvent to dilute the elastomer to get thinner coats. We plan on diluting the elastomer with a solvent recommended by the manufacturer called mesitylene (1,3,5-trimethylbenzene). Attached is the MSDS sheet for this chemical.
