Not knowing what a product does can make us rather tense. We need to relax, because often a product's name gives away its purpose.
Battenfeld Batco's X-8401 is a lithium surface sealing grease. Lithium grease, like all grease, is a surfactant, i.e. they reduce the tension and friction along surfaces. Lithium-based lubes work particularly well due to their high melting point. Speaking of which, to find out more about this grease and its chemical composition: read the MSDS (found above).
