Thread: Resinating a WIP

Spent most of the last thirty years of my work life often pouring resin prototypes and making silicone molds. Vacuum is the only real answer! And 28"Hg or higher. The stuff will foam over so drop the vac to ambient pressure and pull it up again a few times to shake out all the bubbles without having excess resin all over the place. Many resin's hate water and will foam and spew readily with any moisture at all in the mold. It pays to keep molds in a dehydrator before use.
Have fun and use a vent fan! Most of the heavy metals have been taken out of the formulas by now but, I hate going to the MD and getting a MRI and CT scan every year for "shadows." And it is horribly expensive!
