Key Benefits to Armoloy Medical Coatings

Armoloy TDC® is a precise, biocompatible, pure, metallic chromium coating for medical, surgical, laboratory and clean room environments. Highly trained coating professionals and strict process controls allow for a uniform coating that is unparalleled in performance. The coatings are completely inert, non-magnetic , USP 10993-10, 10993-6, 10993-11 tested. The coating improves the physical appearance of medical instruments and, more importantly, provides functional enhancements to their performance in the following ways:


  • Biocompatible Tested 10993-10 / 10993-6 / 10993-11
  • Arrests corrosion from sterilization and laser marking while maintaining new appearance
  • Increases wear resistance
  • Maintains cutting edges
  • Provides a hard, scratch resistant, nonstick, easy clean surface
  • Increases surface hardness
  • Eliminates galling, fretting, spalling
  • Ability to easily remove and reapply
  • Arrests metallic debris and particulate matter
  • Provides smooth sliding surfaces
  • Reduces high intensity light reflection/refraction and glare
  • Provides long lasting, clean, pristine new appearance
  • Chemical and detergent resistant
  • Hydrophobic

NAMSA Test Results:

United States Pharmacopeia; ISO 10993-10
USP Intracutaneous Study
No Localized Tissue Reaction
Irritation tests are utilized to assess the irritation potential of medical devices, bio-materials, or their extracts exposed to eye, skin, or mucous membranes. The test(s) are performed using a model appropriate for the route (skin, eye, mucosa) and duration of exposure or contact.
United States Pharmacopeia; ISO 10993-6
USP Muscle Implantation Study 7 Day
Non Irritating to Muscle Tissue
Implantation tests are performed to evaluate the local d pathological effects on living tissue, at both the gross level and microscopic level, after implantation of samples of medical Implantation tests are performed to evaluate the local pathological effects on living tissue, at both the gross level and microscopic level, after implantation of samples of medical devices or bio-materials. The implant location is based on the clinical site of use. Implant duration’s are based on the need to evaluate the tissue response over multiple intervals and along with the sample’s inertness and absorptive characteristics.
U.S. Pharmacopeial Convention; ISO 10993-11
Acute Systemic - No Systemic Toxicity
No Systemic Toxicity
Systemic Toxicity tests evaluate the generalized biological effects to organs and tissues following exposure to a medical devices, bio-material, or their extracts. The term systemic implies that the exposure occurs by one route and the toxic substance is carried to distant locations causing an adverse effect. Systemic toxicity is typically evaluated in studies of acute, sub-acute, sub-chronic, and chronic duration based on the device’s intended exposure.
