Drying oils are a good choice for wood coating, whenever a renewable product is wanted. One of the most common and widely used drying oil is linseed oil. Linseed oil has a high drying power, thanks to the presence of linolenic acid, linoleic acid and oleic acid, which are all unsaturated fatty acids. Although alkyds have replaced them in the market, drying oils are regaining interest. New formulations, where renewable components are included, are a valid alternative to formulations based exclusively on petrochemical raw materials. The film formation for drying oils and alkyd resins requires the oxygen absorption to start. To accelerate this process it is necessary to use special metal salts, so called driers. In this work, three primary driers, based on cobalt, iron and manganese are compared.
