The conjugated fatty acids/vegetable oils are used as effective monomers to prepare different biopolymers and resins and are more important to the paint and food industries, but also have a role in lubricant industry to make high viscosity oils. Conjugated fatty acids/vegetable oils are of great interest in industry due to the presence of conjugated double bonds that make them highly reactive towards polymerization through the Diels-Alder reaction. This reaction can be used to prepare various bioplastics, ranging from elastomers to very hard materials, like resins [145,146]. Conjugated fatty acids are used to prepare drying oils that are used as coating compositions in paints, varnishes, and inks [147,148]. Conjugated oils are also used as resins or binders applied on wood products.

The AP 2 + 2 system consisted of two layers of a high-quality primer comprising red lead applied in linseed oil, over which were applied two or more AP layers. The system comprised a top paint layer of leafing aluminium pigments and MIO pigments bound in a mixture of linseed and tung oil (IVA 1935, 1961; Tengstrand 1948).9Tung oil is a drying oil that consists of ~84% of α-eleostearic acid, a conjugated fatty acid with three double bonds which is readily oxidized and polymerised (Xia and Larock 2010). The function of the paint layers is explained in Figure 5.
