Green strontium aluminate phosphorescent pigment is
currently sold in 7 grades. At the wholesale level, the difference
is brightness vs. cost. As you can see from above, there is a
large difference in brightness between grades. Over 98% of
phosphorescent material produced is Grade 4 and 5, which is available
from dozens of discount sources. Glow Inc. purchases over 90% of
the Grade 0 manufactured in the world.
Phosphorescent pigments are not a dye. They
maintain their original shape and they do not color the medium around
them. Larger particles, within a grade, are brighter. However,
larger particle sizes create rough textured surfaces. On thin
applications, they can also create a speckled look when observed
closely. Therefore, smaller particle sizes look and feel smoother
at the cost of brightness. Additionally, smaller particle sizes
are more likely to work in air brushes and printers. Smaller
particle sizes are also less likely to settle in their medium.

particles, consider reading our technical article "The
Note: It is a common misconception that all
strontium aluminate pigments are of similar grade and that particle size
is the sole determinant of brightness. Another myth is that grade
is the same as particle size. As you can see from the chart above,
this is not true. A comparison of our
Sample Pack to other
manufacturers will quickly show which grade they are selling.
Bright white backgrounds are less likely to show the
above-mentioned speckled appearance for large particle pigments.
White will also reflect the glow on thin applications, improving
performance. If possible, stay clear from dark backgrounds.
Coated Pigments have a thin protective layer added to each
individual particle. This prevents them from dissolving in water
or being damaged by some acids. They are also more durable.
Daytime powders are a mix of
phosphorescent pigment and fluorescent pigment. The result is a
product that glows in the dark in one color and is vibrant in the light
in different color.
