R
& E Types - Inorganic Invisible Fluorescents
R
& E types are extremely stable and will far outlive any coating
plastic or ink system you care to use them in. They are crystalline
however, and therefore can not be ground, so are not suitable for
very thin films. They are extremely heat stable and will generally
be able to withstand temperature in excess of 1000°C.
