Ja, wenn es das ist, dann ist es eine Art sehr dünner Teflonbeschichtung für Korrosionsschutz und Reibwertverminderung:
... Black-T® is a PTFE product, similar to Teflon® in chemical composition, but it is applied at a fraction of the thickness of other PTFE and new-age finishes (0.3-0.7 mils thick instead of 1-3 mils thick). Black-T is thin enough that it can be applied to most firearm components without affecting fit or performance, and it can even be applied to springs with no issue.
Independent lab testing has rated the thin version of our coating at 1,500 hours on the ASTM 117 salt spray test and beyond 4,000 hours for our thicker coating. Black-T® coating is incredibly durable because it is chemically bonded to virtually any ferrous or nonferrous metals, including steel, aluminum, titanium, magnesium, brass, and even some plastics and composites. The Black-T finish also boasts a low coefficient of friction, eliminating the need for lubrication on firearms altogether, except for the barrel bore.
But while Black-T® has been the gold standard for corrosion-resistant coatings on firearms for decades, its possible applications are virtually endless.
