Oils & Fats

Siccative (drying) oils are vegetable oils that dry to a hard finish at normal room temperature. The polyunsaturated acid (linoleic and linolenic acids) content of a drying oil is high. Such oils are used in paint and in other paint and wood-finishing applications. Walnut, sunflower, safflower, dammar, linseed are drying oils. Paint may also include additional siccative such as alkyd resin. Palm oil is used in the synthesis of alkyd resins.
