Modified Impregnation Coating


Blue Dichtol is a modified impregnation coating for new (and newly repaired) castings. It is compatible with all ferrous and nonferrous materials, and composites. This capillary sealer impregnates micro-pores and hairline cracks without vacuum or pressure, forming a protective barrier to gases and liquids. It can be applied to raw metal, or to castings that have been coated with plasma, arc spray or HVOF coatings.
