Antiviral performance (prototype example)

Methods

A virus solution of enveloped or non-enveloped virus was dropped on a polyester (PET) film treated with CufitecTM Coating Agent to examine the virus infectivity titer after 60 minutes of contact time using the plaque method.
*In-house test conducted in accordance with ISO 21702 with only the contact time changed

Results

In both cases of enveloped virus (left graph) and non-enveloped virus (right graph), the virus infectivity titer was reduced by more than 99.9% in 60 minutes compared to the untreated product (detection limit).

Antibacterial performance (prototype example)

Methods

A gram-negative or gram-positive bacteria solution was dropped on a polyester (PET) film treated with CufitecTM Coating Agent to examine the viable bacteria count after 30 minutes of contact time using the mixed plate culture method (colony method).
*In-house test conducted in accordance with JIS Z 2801 with only the contact time changed

Results

In both cases of gram-negative bacteria (left graph) and gram-positive bacteria (right graph), the viable bacteria count was reduced by more than 99.99% in 30 minutes compared to the untreated product (detection limit).
