The impregnation process to seal porous castings and other materials can be carried out using several methods, a few of which are listed below:
Vacuum and Vacuum Pressure Impregnation Process
We provide Vacuum and Vacuum Pressure Impregnation using industry leading thermo curing polyfunctional methacrylate resins. Futher details of our process can be found here http://www.impregnation.co.uk/process/
Internal Pressure Impregnation Process
Large castings occasionally outsize our conventional vacuum process lines. In these cases, we are usually able to fill the casting with suitable resin and apply air hydraulic pressure to force the resin into the porosity.
