HELP on silicone grease

i have a situation with silicone grease Dow Corning 111 that is Applied to a proximal end of a plastic shaft that houses two metal (SS) plates, the silicone grease is migrating to the distal end thru the metal plates, (plates are tight togheter) still the grease is "flowing", there is no agents or any mechanical stress.

Note both SS plates are coated previously with vegetal based Kritox.

Dow 111 have no control over the viscosity, only penetration, no shift observed.

What can cause or promote this "flow"¿

Any HELP is greatly appreciated

Surface tension of the grease, and perhaps gravity.
