Copper Alloys’ Antimicrobial Effects Make PVD Copper Coatings an Ideal Solution

Scientific evidence shows that certain copper metal alloys have antimicrobial properties.1,3,4,5 Studies have also demonstrated that when certain coatings containing these alloys are applied to the surface of products, they can provide antimicrobial protection of the surface.2

VaporTech® has been researching the antimicrobial properties of copper PVD coating for more than five years. Our proprietary antimicrobial coatings are pending approval from the Environmental Protection Agency (EPA).

How are metals like copper antimicrobial?

Copper is an inherently antimicrobial material. Upon contact, ions of copper damage microbe cell membranes and disrupt the internal functions critical to the viability of bacteria, viruses, and fungi.4 While toxic to many microorganisms, copper surfaces are safe to touch. 1 Governments and large corporations have been exploring alternatives to mitigate the cross-contamination of dangerous microorganisms. From household items to mass transit, the search for non-chemical lines of defense has created a new market for copper products.

Benefits of antimicrobial copper PVD coatings

Antimicrobial copper PVD coatings are high quality, wear-resistant, and cost-effective.
