Re: Impregnating/stabilizing blanks questions

Good morning Barry

Had a friend a,few years back who had the same idea. He forgot about the physical chemistry. When solvents have reduced pressures, the boiling point lowers and he sucked all the solvent as vapor through the vacuum pump. He ended up with the residual non-volitile resin mess, damaged seals in the pump, and an angry spouse when the solvent vapors migrated into the house. He might have come close to an explosive mixture (beyond the spouse) but it did not happen. Water is a solvent and the pressure - boiling point are well documented.

The vacuum stabilization processes use non-boiling fluids that set with heat, UV or similar.
