LINSEED OIL THE ALL-ROUNDER It has an aromatic smell of hay that is also described as herbaceous, musty and a bit toasty. The cultivation of oil flax or fibrous flax dates back to the Stone Age already, the sowing and the harvest are also to be seen on Old Egyp- tian mural paintings. The flax plant delivers the linseed oil as well as the fibres that are spun to linen fabrics. The clear golden yellow oil is won from the linseed, i.e. the ripe seeds of the oil flax. It is contained in many products because of its high amount of saturated and polysaturated fatty acids. It is used in binding agents for the pro- duction of paints and lacquers, in foodstuffs and in cosmetics – a truly versatile oil. Linseed oil - decated The seeds of the small oil flax with its wonder- fully blue, sometimes white blossoms get harvested in July or August at the latest. Then the oil is won from the flax seed in a careful proce- dure by decating in a screw press. The linseed is pressed slowly through the screw press by a cylinder that exerts slight pressure. In this process, the oil tem- perature reaches a maximum of 40 °C. Higher temperatures would lead to a detach- ment of other plant components which would impair the quality of the oil. The careful decating process makes lin- seed oil one of the most precious and most expensive oils. In paint production only decated oils can be used. The remaining parts of the oil flax, e.g. the chaff, straw, and the presscake, are used as cattle fodder or in insulating materials. Nowadays, the oil is pressed in very big oil mills which can lead to higher temperatures. The mucilage extracted in the process gets coagulated by addition of mild acids and is then filtered out. Use at AURO At AURO we use linseed oil from certified organic farming (cof ) because of its outstanding technical and physical properties. The warm lustre, the elasticity, the penetration capabilty and the moisture-regulating features make this sustainable plant raw material an ideal choice for the binding agents in AURO products.
