Iron
While iron exhibits very little drying at room temperature, it becomes very active at elevated temperatures, and is therefore extensively used in baking finishes. Iron driers provide tough, durable, yet very flexible films with extremely good gloss. In air-dry finishes, iron is particularly useful in eliminating the after-tack common to oxide pigmented paints and unprocessed fish-oil compositions. Iron also functions as a wetting agent and helps to obtain quicker and better grinds when used with carbon black pigments.
Because of their dark color and high staining power, iron driers are used primarily in dark-colored baking enamels. In addition, they are generally used to replace lead driers in aluminum paints since iron does not adversely affect the leafing of aluminum pigments.
