The Vacuum Impregnation Process

1. Impregnation The impregnation stage is the first part of the porosity sealing process. Air is evacuated from the porosity under dry vacuum and a liquid sealant is drawn into the porosity, filling any voids and leak paths. 2. Drain Once the sealant has filled the porosity the components are rotated to drain excess sealant. 3. Cold Wash After the excess sealant has been drained, the components are rotated under a wash water solution to remove any excess sealant from external component surfaces. 4. Hot Cure Finally, a hot cure cycle is used which polymerises the sealant, turning it from a liquid state to a solid polymer, sealing porosity and leak paths within the component.
