Introduction-
This series is
a range of insoluble phosphorescent pigments with extended
afterglows for general use in paints, plastics, inks and security
applications.
This series of
phosphorescent pigments has been designed for use primarily
in solvent and water based paints but may also be used in
molded and laminar plastics, screen inks, rubbers and latex,
and many other applications.
These series pigments
should not be milled or ground as this damages their crystalline
structure leading to reduction in luminescent emissions,they
generally have high density, so liquid dispersions containing
it should contain suspending agents to reduce hard setting.
The shelf life
of this series is indefinite if stored in sealed containers,
and they are generally considered to be of low toxicity when
used as recommended. However, contact with strong mineral
acids should be avoided as this may lead to the liberation
of hydrogen sulfide.
