 Main purposes: 
 A, dimer acid with amines in the different amount of additives (materials) participation can generate a variety of different molecular weight of polyamide, a large number of applications in manufacturing plastic embossing printing ink. 
 B, dimer acid reacted with the polyamine polyamide with amine activity, widely used in manufacturing two-component epoxy paint, curing agents and epoxy binder, cured with a good mechanical and electrochemical properties. In addition, can also be used in the manufacture of various low-temperature, low pressure of special lubricants, metal working oil. 
 C, dimer acid used in manufacture of hot melt adhesive, which is widely used in the manufacture of electronic, electrical and automotive interior thermoplastic products, shoes and so on. 
 Packing: plastic drum or iron drum, barrel, net weight 190kg.
