New antimicrobial additive for paints and surface coatings brings peace of mind where it matters most

With current global health concerns, we’ve never been more aware of the bacteria and viruses that live on surfaces all around us. We wash our hands regularly and thoroughly; we sanitize the surfaces that we come into contact with; and yet it still doesn’t always feel like enough to protect ourselves and our families from germs.

If recontamination is constant, shouldn't decontamination be constant, too? The EPA recently acknowledged the importance of surfaces with in-built antimicrobial activity to supplement the use of disinfectants.

Corning® Guardiant® is an antimicrobial additive that can be dosed into paints and coatings. Testing performed at the University of Arizona’s microbiology lab headed up by Dr. Charles Gerba show that coatings containing Corning Guardiant can continuously kill 99.9% of germs* on walls and other coated surfaces, including the virus that causes COVID-19.

Guardiant is powered by the antimicrobial properties of copper.

Corning scientists invented a glass composition that traps copper ions inside a glass matrix and keeps the most effective form of copper readily available for reducing harmful germs. Corning is currently collaborating with leading paint and coatings manufacturers around the world to develop products containing Corning Guardiant that meet government and regulatory requirements. Prior to making claims in the United States against harmful germs, finished products incorporating Corning Guardiant must first be registered with the U.S. EPA.
