Typical Antimicrobial Substances
Copper (Cu) kills bacteria with high efficiency. But Antimicrobial Cu Film is not recommendable for use in display products, due to its yellowish color and low transparency.
Zinc Oxide (ZnO) is an efficient antimicrobial agent, included in sunblocks for skin protection. ZnO has been listed as “Generally Recognized as Safe” (GRAS) by US FDA.
Silver (Ag) has been used for centuries as an antimicrobial to kill bacteria. Widely used in Medical, Cosmetics and Consumer applications.
Titanium Dioxide (TiO2) is widely used as photocatalytic disinfecting material for surface coatings. It’s been approved by FDA for uses in human food, drugs, cosmetics and food packaging.
