It is polymerizedby unsaturated C18 fatty acid. Dimer acid is usually polymerized byoctadecadienoic acid under the catalytic polymerization and generally has thesix-carbon structure. At high temperature, hydroxide radical can occur allkinds of reacti**, and the common one is react with amine to yield acid amide.Plant dimer fatty acid is called dimer acid for short which is made under themutual polymerization among the molecules of octadecadienoic acid. Properties: Yellowish oleosus transparent liquid, contains traces of monomeracid and a small quantity of octadecadienoic acid, soluble with a majority oforganic solvent, insoluble in water, has good stability, poisonless,non-volatile, high flash point and burning point, doesn’t freeze at lowtemperature, high viscosity and excellent adhesive capacity. Use: It is mainly used to produce alkyd resin, polyamide resin, printing ink,coating, rust inhibitor, and plasticiser, also can be used as main raw materialof bond, textile and detergent, or surface active agent as lubricant, anti-rustoil, or food additive, etc. Packaging: packed in plastic drum or PP-R metal pail, net weight 190kg/drum
