During the development of this technology, special attention was focused on ensuring that phosphorescence was long-lasting and did not diminish in strength. BerlaGlow products are resistant to water and suffer neither greying nor the loss of luminescence over time that is associated with this. The systems satisfy all current physiological and ecological requirements, are not radioactive and contain no listed heavy metals or other questionable substances. 

These phosphorescent coatings have primarily been developed for the visual and functional enhancement of dials, hands and bezels in the watchmaking industry. They are suitable for all conventional methods of application, including pad and screen printing, coating and spraying. Products are supplied ready to use, so that it is not necessary to mix powder and binder. A broad range of solid and phosphorescent colours is available and individual shades can be produced as required.
