Tall oil fatty acid (TOFA) with high fatty acid content and low content of rosin acids and unsaponifiables. The
light colour together with excellent colour stability and air drying propeties are derived from its origin, the northern pine.
The superior chemical reactivity of TOFA2 is due to its long carbon chain (C18), the acid function of carboxyl group (-COOH) and the unsaturation of the double bonds. That is why TOFA2 is an excellent raw material for alkyd resins, dimer acids, fa-esters, fa-soaps, faethoxylates,fa-amines and many other chemicals.
Tall oil fatty acids are a product of crude tall oil vacuum distillation. The fraction of tall oil fatty acids is represented by liolic, linolenic, oleinic and other acids. The fraction of tall oil fatty acids is obtained after separation of tall oil pitch, tall oil rosin, and distilled tall oil fractions, as well as a fraction of unsaponifiable matters.
