Abstract: The unique properties of pulsed ultraviolet (UV) light make it an ideal technology for both surface sanitization and photochemical processing in the development of hygienic paints and coatings. This paper will discuss the means by which pulsed light can sanitize and sterilize various infectious disease-contaminated surfaces by attacking bacteria, viruses, fungi, and protozoa on a molecular level, thus modifying the cell structure of their DNA. Pulsed UV is an environmentally benign technology, providing intense peak energy that easily penetrates thick and opaque substrates. The benefits of pulsed UV for curing adhesives and surface preparation for paints and coatings are also discussed.
