Dimer acids is also known as dimerized fatty acids, are dicarboxylic acids produce by dimerizing unsaturated fatty acids exerted from tall oil, mostly on clay catalysts. Major use of dimer acid is in polymer building block or rheology modifier. Heat and hydrolytic stability add value in dimer acid. In addition, water repellence and pigment wetting properties of the final polymers such as polyamides, epoxy resins, polyesters are based upon these natural polymerized fatty acids. There are two ...
