Acid Diamer (Poly aminated Fatty Acid)

Polyamide Fatty Acid Dimer, commonly known as Dimer Acid or Dimerized Fatty Acid, is a C₃₆ dibasic fatty acid produced by the polymerization of unsaturated C18 fatty acids (typically derived from tall oil fatty acid – TOFA). This dimerized fatty acid is further reacted with polyamines to produce polyamides, which are extensively used as primary and secondary emulsifiers in oil-based and synthetic-based drilling fluids. It provides excellent lubricity, torque reduction, thermal stability, and emulsion stability in both OBM and WBM systems
