Durable coloration of stainless steel

SPECTRACOAT® is a hard & wear resistant color coating, hypoallergenic, sterilizable, biocompatible and implantable. SPECTRACOAT® ist eine harte und verschleissfeste Farbbeschichtung. Sie ist hautverträglich, sterilisierbar, biokompatibel und implantierbar.

Durable coloration of stainless steel

SPECTRACOAT® comprises a coating system of metal and oxide. Its thickness is 2 to 3 microns. A large range of different colors can be obtained, comparable to anodized titanium. The coating, however, shows far superior wear resistance when compared to colored titanium.

 SPECTRACOAT® can be applied not only to stainless steel but also to other steels, copper, brass aluminum, nickel, titanium, ceramics, and plastics.

 SPECTRACOAT® is mainly used for decoration and identification. A wide and precise gamut of warm, dense and metallic colors makes it suitable for artistic creativity. The wear resistance is far superior to previous or other products.

 A wear test consisting in 150 cycles of the reciprocal movement against normalized fabric (EMPA Art No 701 ou 702), under 0.5 Kg load, in dry as well as in humid environment, showed excellent resistance in both tests.

 In a 24h « accelerated » wear test, i.e in a vibrating vessel containing ceramic pellets, the Spectracoat coating applied to a watch bezel showed only partial removal on raised sharp edges.

 Excellent resistance to sun and salt spray exposure.

The standard sunlight exposure test for watches (72h at 5.5 mW/cm2) caused no degradation.

The standard salt spray test (96h at 35°C ) caused no measurable corrosion.

Medical instruments, identified with different colors, successfully passed cleaning, disinfection, and sterilization procedures as well as the abrasive handling in metallic baskets. All colors showed no degradation after a hundred cleaning cycles in alkaline detergent, followed by disinfection at 60°C, plus more than 500 sterilization cycles at 134°C.
