Dimer Acid| CAS 61788-89-4

Description

Product Description
Dimer Acid (CAS 61788-89-4) is a dibasic acid produced by dimerizing unsaturated fatty acids, primarily derived from vegetable sources such as oleic acid or tall oil fatty acids. It typically consists of a C36 dicarboxylic acid structure with both aliphatic cyclic and branched chains, offering a unique combination of flexibility, hydrophobicity, and thermal stability. This versatile chemical intermediate is widely used in polymer synthesis, corrosion inhibitors, lubricants, and adhesives due to its long hydrocarbon chain and reactive carboxyl groups.
