Elastomers are basically liquids held in the solid state by cross-linked polymeric bonds. With wear and time, these bonds  fail within the polymer chain, resulting in a free carbon atom at the end of the chain. Carbon will then seek a reaction site with the metal, thus forming metal carbide. This reaction results in the common occurrence of the rubber seal sticking to the seal face, and having to be aggressively cleaned off for the seal face to be  reused. In difficult to access seals, this can result in very costly repairs, such has downhole oilfield seal applications.

A patented MagIon metal lubricant film system protects the elastomer by providing a three-layer coating that is impervious to carbide reaction. An outer layer  is applied, which results in metallic seal performance, yet with full elasticity!
