PROCESS PAGE

Q. What is vacuum impregnation?
A. Vacuum Impregnation is the process of sealing the porosity in castings. The impregnation material is introduced into the porosity within the wall thickness of the casting through vacuum. The sealant liquid is subsequently solidified by heating at elevated temperature. The process is carried out using the Impregseal Dry Wet Porosity Sealing Systems using our world renowned and approved Sealants.
