Dimer Acids and Trimer Acids
Dimer acids (dimerized fatty acids) are dicarboxylic acids produced by dimerizing unsaturated fatty acids obtained from tall oil, oleic acid, canola oil or cottonseed oil, usually on clay catalysts. Dimer acids can be used to synthesize polyamide resins and hot melt adhesives. They are also used in alkyd resins, adhesives, surfactants, fuel oil additives and lubricants. Dimer acids are light yellow transparent viscous liquids. They are also non-toxic.
A dimer acid of predominantly stearic acid is termed a C36 dimer acid. The chemistry can be taken further to form a trimer acid where the product consists of three fatty acid molecules.
Univar offers dimer acids produced from oleic acid, canola oil and tall oil fatty acids.
