Batco的X-8401是一种锂表面密封润滑脂。 与所有润滑脂一样，锂润滑脂是一种表面活性剂，即它们可以降低表面的张力和摩擦力。 锂基润滑剂由于其高熔点而特别好地工作。

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.
