Henkel launches Loctite MS 9810 formed-in-place automotive gasketing sealant

Henkel has launched Loctite MS 9810, a one-component MS Polymer formed-in-place gasketing sealant for automotive powertrain and electronic housing applications. The product cures through contact with airborne moisture at room temperature, is non-permeable to hydrocarbons, maintains seal integrity in hot oils and powertrain fluids, and is free of silicone and oxime chemistry. Henkel says it is compatible with Bergquist Gap Fillers and can be leak-tested before curing.

Key facts

Market context

Formed-in-place gasketing sealants are liquid materials dispensed as a bead onto a housing flange, where they cure into a flexible elastomeric seal that replaces pre-cut paper or rubber gaskets. MS Polymer is a silane-terminated polyether backbone that cures by reacting with atmospheric moisture, and it is valued for combining elastic recovery with adhesion to metals and plastics without the isocyanate or silicone chemistries used in some competing systems. Demand for these materials is driven mainly by automotive production, particularly powertrain components, transmissions, axles, and electronic control housings, where seals must resist hot oils, fuels, and coolants over long service lives. Electric drivetrains and e-motor assemblies are expanding the number of sealed housings per vehicle, which supports demand for one-component systems that can be applied by robot and leak-tested before cure. Suppliers in this segment compete on cure speed, fluid resistance, and process compatibility with automakers' assembly lines.
