Antimicrobial Coating

Medical devices require direct contact with body fluids which carries risk of device-related infections. Medical devices with plastic or metal surface are potential substrates for microbial colonization and biofilm formation. Antimicrobial coatings are thus needed to prevent the transfer of external bacteria into the body environment. 

jMedtech’s antimicrobial coatings are developed to release anti-microbial compounds in a controllable and sustainable way, which effectively fights infectious bacteria while minimizing toxicity in tissues. 

Antimicrobial coatings are also customizable to your specific application and durability requirements. Such a coating has potential application in many implanted medical devices including catheters, tubes, artificial joints and stents.

Antimicrobial Coating

Features and Properties

  • Effectiveness– Prevent growth of commonly occurring organism in body fluid system, such as S. aureus, S. epidermidis, E. coli, etc.
    – Reduce bacterial adherence and minimise biofilm formation

  • Long lasting– Antimicrobial coating can maintain a desired antimicrobial agent releasing profile for above 30 days.

  • Applicable surface– Antimicrobial coating can be applied to inner surface only, outer surface only or both inner and outer surface.

  • Safe– Antimicrobial coating maintains low toxicity to surrounding tissues.

  • Substrate coated – Antimicrobial coating can be applied to various plastic surface.

  • Flexibility – coating can withstand bending test without cracking or delaminating.

  • Coating thickness – The dimensional change of device after coating is insignificant.

  • Lubricity – Antimicrobial coating is compatible with hydrophilic coating.

  • Sterilization – Medical devices treated with antimicrobial coating can be sterilized using ethylene oxide (EO), E-beam and Gamma.


Technology    

The antimicrobial coating technology is a modularized coating and heat curing process. For all of materials, one-step coating is sufficient to achieved desired antimicrobial property. No primer coating is required.
