Kastus

Kastus is an Irish nanotechnology and advanced materials company that develops photocatalytic surface treatments for glass and related surfaces. The company was originally known for antimicrobial and antiviral coatings designed to reduce contamination on touch surfaces, glass, ceramics, and indoor environments. More recently, Kastus has expanded into anti-soiling coatings for solar-panel cover glass, positioning its technology as a permanent, embedded surface treatment that improves cleanliness and energy yield over the lifetime of the panel. Its products are materials and coating technologies rather than therapeutic drug programs, and the business appears to be commercially active as a private company headquartered in Dublin.
