I will cast with Smooth-on Ecoflex 00-35 Fast Platinum silicon rubber compound using a home made mold and I need to have the item release from the mold and be easy to clean. Due to this task coming up quickly and limited materials being on hand I will use machined PVC as my initial mold. A follow-on step will require adhesion to the silicon rubber so I need it to be clean. It does not need to be "NASA clean" or "food safe clean" but it does need to be pretty clean.
There are several mold release agents available on Amazon and Google will return many more. In my search last night I didn't come across "water clean up" or "easy to clean" for any of them. Does anyone have any suggestions for either a slippery coating that is permanent or a mold release agent that is easy to clean off (water or alcohol)?
As a follow-up, PVC is probably not the ideal material. Polypropylene and UHMW are difficult to machine. Right now my mold material wish list has Teflon at the top followed by HDPE, delrin and ABS. Any suggestions for the mold material for version 2 of the mold?
Thank you,
Bruce
