Date :Définition
The most widely used drying or oxidizing oil in such products as exterior paints, printing inks, putty, and (formerly) linoleum. It is obtained by crushing seeds of the flax plant and thus is also called flaxseed oil. It is a mixture of saturated and unsaturated fatty acids, the latter being oleic, linoleic, and linolenic. It dries to a hard, resistant film as a result of polymerization caused by air oxidation.
Note :
It may be thickened to increase its drying properties by blowing air through it at about 93 °C (200 °F). Heating it to about 260 °C (500 °F), often with admixed metallic driers, causes still further increases in viscosity. This product is called heat-bodied or (erroneouly) "boiled" linseed oil (actually it has no boiling point). Other names used are stan oil and resinoid. The meal left from the presscake is used as an animal feed.
