Vacuum impregnation enables metal and electronics parts of vehicles to be fully sealed against fluids, gases and other external influences and ensures they are ready for just-in-time assembly. After impregnation all parts are clean, free of corrosion or oxidation, and are ready for use without post-treatment. LOCTITE® vacuum impregnation solutions provide resins that cure to an impermeable thermoset polymer. This makes it possible to permanently seal pores or leakpaths to enable quality lightweight, thin-walled die-casted parts or electronic components.

Henkel’s complete LOCTITE Impregnation Solutions (LIS) offers impregnation resins, systems and a customized service through both external or on-site impregnation service centers. Through LIS, Henkel offers the automotive industry a one-of-a-kind, fully automated impregnation system, and its high-tech resins deliver consistent quality and unmatched sealing performance. With this we enable our customers to meet in full their process needs and the associated industry challenges.
