infiltrating with vacuum under the hood
One word of caution!! Infiltrating at room
temperature must be done carefully because sometimes the polymer will
spontaneously polymerize leaving you will one massive block, making you a
very unhappy camper. You did not say which plastic you were using
but you may want to pull vacuum on the dessicator and then place the
dessicator in the refrigerator which will slow down the polymerization
process. The dessicator can be released and vacuum pulled again
several times during the day by just putting your vacuum pump next to the
refrigerator. At the VA in Salt Lake we had house vacuum on the
wall next to the refrigerator. We drilled a hole in the side of the
refrigerator and passed a hose through the refrigerator wall to multiple
vacuum dessicators.
Hope this helps,
