Description
A substance that catalyzes the drying of oil-based paints, varnishes and inks. Siccatives (also called drying agents) are usually metallic salts of organic acids (i.e., metal soaps). Examples are cobalt linoleate, cobalt oleate, and cobalt naphthenate. Organic acid salts of most heavy metals, such as manganese, cerium, lead, chromium, iron, and zinc, can be effective driers. A prepared liquid drier generally acts as a catalyst to speed the polymerization and oxidation processes involved in the drying of oils and alkyds. Some pigments also act as driers, such as lead oxide and manganese oxide. In recent years nonmetallic driers, such as orthophenathroline, are being used as replacement for the toxic heavy metal driers.
Synonyms and Related Terms

- Excess driers can cause surface skinning and wrinkling.
