ABSTRACT:
An article having surfaces in sliding contact is lubricated at the interface with a multi component system. A first crosslinked basement lubricant is coated onto a surface, such as a syringe barrel. A second lubricant is coated over the crosslinked lubricant. The second surface, such as a syringe stopper is engaged with the first surface. A second aspect of the invention is a method for lubricating an article such as a syringe. A low viscosity prebasement lubricant is evenly coated onto the inside surface of the syringe barrel and then crosslinked by a plasma to a viscous liquid or substantially solid basement lubricant. A second surface lubricant is then applied over the basement lubricant.
