Luminous colours have been in existence for a long time, what is so special about trigalight®?
With conventional luminous colours, a luminous mass is applied to a carrier material which is then covered with a protective varnish. After just a very short time, radioactive disintegration particles diffuse through the varnish and enrich surrounding materials. With trigalight, the radioactive gas (tritium) is firmly sealed and isolated in a glass capillary. No diffusion results. As no moisture can penetrate either, the light source remains isolated, free of contaminants and shines reliably over a period of years.
