Antiviral Performance
◆ Antiviral Performance in Resins
MK-T-505 was incorporated into various resin pellets, including ABS, PET, and PP, and molded into antiviral-treated test specimens. The specimens were evaluated for activity against influenza virus in accordance with ISO 21702, Measurement of Antiviral Activity on Plastics and Other Non-Porous Surfaces.
