AMF™ Series Antimicrobial Films
 Dontech antimicrobial coatings are designed for touch screens, membrane switches, and optical overlays used in electronic display applications. To minimize microbial growth, Dontech’s AMF Series films contain slow release silver ions that inhibit the growth of many common bacteria, molds and fungi. The high optical transparency and durability of the AMF films make them ideal for protecting electronic displays and overlays used in medical, food processing, ATM and kiosk applications.
The silver-based antimicrobial coating is non-hazardous, and mechanically, chemically and thermally stable. Dontech’s AMF Series films provide the following performance enhancements:
- Interrupt cellular metabolism
- Prevent cellular reproduction
- Protect against a variety of bacteria and mold
- Decrease microbial growth by 99.99%
- Effective against surface propagation due to contact
- Controlled release mechanism utilizing active silver zeolite carrier
- Good optical transmission and mechanical durability
