LK91S Reusable Vacuum Impregnation Sealant

Product Description

LK 91S is a low viscosity liquid sealant designed for sealing porosity in metal castings. It may also be used to seal microscopic voids and tight interfaces in other materials. This sealant is specifically formulated for wash water removal and reuse. This is accomplished with the aide of a recycling system. LK 91S is a typically applied with a vacuum impregnation process that removes air from porosity and then saturates the part with liquid sealant. At an elevated temperature, the liquid rapidly polymerizes to form a tough thermoset polymer that permanently seals the internal cavities. Excess liquid sealant is rinsed from the outside of the part with plain water. Parts processed with LK91S are sealed internally but remain cosmetically and dimensionally unchanged.


LK91S is used to seal castings and powder metal components against leakage of air, water, coolants, oils and other fluids. Engines, heads, manifolds and housings in automotive powertrains and fluid handling systems have been sealed successfully for decades.
