Any contaminants in casting porosity will inhibit and prevent the unrestricted flow of the sealant into the porosity. In order to properly seal porosity, parts must be clean. The most effective way to clean parts prior to vacuum impregnation is through vacuum vapor degreasing.
Vacuum vapor degreasing is an environmentally friendly process that dissolves contaminants while in an airless environment. The vapors travel unimpeded to the part surface and help draw out contaminants from the porosity. The process not only removes contaminants, but dries the parts without fear of oxidation.
Godfrey & Wing’s vacuum vapor degreasing eliminates the risk of sealant contamination and enables castings to be properly sealed.
