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.

The Armoloy family of coatings are specifically designed to keep machinery and equipment running longer. For increased wear life, reduced friction, protection from corrosion and galling, and many other benefits, Armoloy of Illinois provides a full range of metallic surface coatings to the manufacturing community. High precision is our specialty.

Armoloy provides industry-leading protective metallic coatings that benefit various industries, including food processing/packaging, oil/gas extraction, Aerospace, medical, and nuclear industries, to name a few. Metal surface treatments tailored to these applications must withstand extremely harsh conditions and provide added durability capable of extending the life of components and systems. Our experienced staff can help engineer the right metal finishing solution to your application.

Our proprietary metal surface treatments are fully compliant with the industry's most rigorous requirements and certifications. At less than 170ᵒF, the Armoloy metal finish process is considered a "cold process" that will not distort or anneal coated parts. The Armoloy coatings form a hard protective metallic surface with an absolute bond to the base metal that will not affect part tolerances or balance. This thin, precision coating will improve surface hardness and lubricity while dramatically increasing your coated parts' wear life. Our stringent quality requirements and onsite product testing will ensure your parts meet strict industry standards.

Armoloy offers a variety of coating solutions engineered to solve your coating needs. The Armoloy TDC/XADC coating will not flake, chip or peel from your base material ensuring a safe coating process that is food and medical application safe. Your maintenance and machinery expenses will lessen thanks to the coating's increased wear resistance leading to decreased downtime and replacement costs. Don't settle for traditional metallic plating shortcomings when you can have the Armoloy family of coatings protecting your valuable automated systems and components.
