Corning Incorporated announced on Thursday a new breakthrough in glass-ceramic technology, Corning® Guardiant®. Under test methods approved by the U.S. Environmental Protection Agency (EPA), paint and coatings containing Corning Guardiant were shown to kill more than 99.9% of SARS-CoV-2, the virus that causes COVID-19. The tests provide the first demonstration of highly durable antimicrobial activity against SARS-CoV-2. The demonstrated antimicrobial efficacy remained active even after tests simulating six years of scrubbing. The tests were designed to account for the cleaning that a surface could be subjected to over time.
