A new hybrid coating made of polyurethane (PU) and calcium hydroxide (Ca(OH)₂) is proving to be a promising candidate for antiviral surfaces in public and industrial areas. Researchers at McGill University and UQAM report sustained efficacy against two tested human coronaviruses (hCoV-OC43-RLuc and hCoV-229E-RLuc). The result is a more even distribution of the active ingredients with a stable effect on the coating surface.
