ASTEC products can be prepared in a variety of colors. However, the
colors will have a negative impact on the solar reflectivity of the
coating. The following base colors are indicative of the drop in
solar reflectivity:
Base brown has a 12% reflectivity which increases to 16% when mixed
in a 1 (part white) to 1 (part brown) ratio, 20% in a 4 (part white)
to 1 (part brown), and 40% in a 16 to 1 ratio.
Base red has a 22% reflectivity; in the 1 to 1 ratio, it increases
its reflectivity to 26% and reaches 40% in the 4 to 1 ratio.
Base gray has a reflectivity of only 9% which raises to 25% on a 1
to 1 ratio.
Base blue has a reflectivity of only 12% but it increases to 49% on
a 1 to 1 ratio.
Base green on a 1 to 1 ratio starts at 11% and goes up to 53% in a 4
to 1 ratio.
Base yellow indicates a 43% reflectivity on a 1 to 1 ratio, 65%
reflectivity on a 4 to 1 ratio, and 70% reflectivity on a 16 to 1
ratio.
Many clients prefer a loss of reflectivity in exchange for a
livelier color than white. Some consider ASTEC white to be too
reflective and prefer the other elements of ASTEC's Total Solution:
less thermal shock, waterproofing, corrosion control, and
aesthetics.
