Synthetic Yellows
Hoover Color’s SYN-OX® Yellow Iron Oxides are synthetic Yellow Iron Oxides, which can range in color from a brownish yellow to a mid goldenrod yellow. As with all Iron Oxide Pigments, SYN-OX® Yellow Iron Oxides are permanent and lightfast. They possess limited heat stability, but show excellent chemical resistance. SYN-OX® Yellow Iron Oxides produce coatings with high opacity. Hoover Color offers a variety of four standard SYN-OX® Yellow Iron Oxides.
