BALIMED ARGENTA Our antimicrobial silver coating for surgical instruments

Dental instruments and tools
Surgical instruments
Minimally Invasive Surgical (MIS) instruments

Instruments used for invasive surgery all bypass the body's natural lines of defence and consequently pave the way for infections. An instrument coated with BALIMED ARGENTA, creates a surface with an antimicrobial effect. The LR test method (logarithmic reduction of the number of bacteria) was used to demonstrate this effect of the new Ag-doped PVD coatings. The unique properties of BALIMED ARGENTA at a glance.

  • New-generation PVD coatings doped with 2 to 5% silver, therefore high antimicrobial efficacy
  • Antimicrobial activity confirmed by ASTM 2180
  • Log 3 reduction after autoclave cycles (50 times)
  • No cytotoxic effect (ISO 10993-5)
  • Autoclavable
Coating material TiN:Ag
Coating technology Arc
Coating colour Gold
Coating hardness HIT [GPa]* 25 - 29
Coefficient of friction (dry) vs. steel** ~ 0.5
Process temperature [°C] < 350
General remark All given data are approximate values, they depend on application, environment and test condition.
*Coating hardness HIT [GPa] Measured by nano indentation according to ISO 14577. For multilayers the hardness of the different layers varies. Hardness can be adapted to the application.
**Coefficient of friction (dry) vs. steel Determined by ball-on-disc test in dry condition with an Steel ball according to ASTM G99. During run-in the given values may be exceeded.
