Surgical Coating for Life-Saving Tools

The BIO TDC® surgical coating process is a proprietary electroplating technique that creates a micronodular surface texture and is applied to medical instruments and devices to improve their functionality and longevity. Armoloy's biocompatible coatings are designed to be non-toxic and compatible with human tissues, making them ideal for use in various medical applications, including surgical tools and implants.

The primary reasons for using BIO TDC® surgical coating include its ability to enhance wear resistance, prevent corrosion from sterilization processes, reduce friction, and improve the overall aesthetic and functional qualities of medical devices. Its use is essential in environments where durability, cleanliness, and biocompatibility are essential, such as in operating rooms and medical laboratories.

A Guard Against Harsh Sterilization Processes

Armoloy BIO TDC® and ME-92® are engineered to withstand repeated and rigorous sterilization processes essential in the medical field.

Our biocompatible surgical coatings are resistant to various sterilization methods including steam autoclave, STERIS SYSTEM 1, STERRAD Sterilization, and exposure to harsh chemicals. This resilience helps maintain the integrity and functionality of surgical instruments, ensuring they remain corrosion-free and retain their mechanical properties over time, thus extending their usable life significantly.

BIO TDC Features & Benefits

Biocompatible

Certified safe for use in medical devices and instruments, as well as clean-room applications

Hydrophobic

Arrests moisture and water buildup, further enhancing corrosion resistance

Corrosion resistance

Protects instruments from rust and degradation due to frequent sterilization

Reduced light reflection

Ideal for tools used in procedures requiring minimal light interference such as laparoscopic surgery

Non-stick surface

Facilitates easy cleaning and reduces the risk of contamination

High surface hardness

Protects against scratches and abrasions, maintaining functional sharpness of surgical tools

Reapplication capability

Coatings can be removed and reapplied without affecting the base material, which is beneficial for refurbishing and reusing medical tools

Absolute adhesion to base material

Maintains cutting edges and provides a hard, scratch resistant, nonstick, easy to clean surface
