Product Description Dimer Acid (CAS 61788-89-4), also known as dimer fatty acid, is a high-performance mixture of dimerized unsaturated fatty acids (typically derived from linoleic acid in vegetable oils). With a long C36 carbon chain structure, it exhibits exceptional thermal stability, low volatility, and strong compatibility with resins, lubricants, and adhesives-making it a core raw material in industrial manufacturing. Available in 98% high purity, it meets global standards (REACH, FDA) and is widely used in epoxy curing, lubricant additives, and coating resins, addressing the key needs of MIC buyers in chemicals, automotive, and packaging sectors.Main ApplicationsEpoxy Resin Curing Agents: Reacts with epoxy resins to form flexible, high-adhesion cured products-used in structural adhesives (automotive, aerospace) and anti-corrosion coatings (metal pipelines, marine equipment); improves impact resistance and chemical resistance.Lubricant Additives: Acts as a viscosity index improver and anti-wear agent in engine oils, gear oils, and metalworking fluids-reduces friction, extends lubricant service life, and protects metal surfaces from corrosion.Coating & Resin Synthesis: Raw material for alkyd resins, polyester resins, and polyurethane coatings-enhances coating hardness, scratch resistance, and weatherability (suitable for architectural coatings, automotive topcoats).Adhesives: Key component in hot melt adhesives (HMA) and pressure-sensitive adhesives (PSA)-improves tackiness, heat resistance, and bonding strength; used in packaging (carton sealing) and textile lamination.Test ItemIndustrial Grade (98%)Food Grade (98%)Test MethodPurity (Dimer Content)≥98%≥98%Gas Chromatography (GC)Acid Value190-210 mgKOH/g190-205 mgKOH/gTitration (NaOH Standard Solution)Iodine Value≤15 gI2/100g≤12 gI2/100gWijs MethodMelting Point35-45oC38-42oCCapillary MethodMoisture Content≤0.1%≤0.05%Karl Fischer TitrationColor (Gardner)≤8≤6Gardner Color ScaleMonomer + Trimer Content≤2%≤1.5%GCHeavy Metals (Pb)≤0.0005%≤0.0001%ICP-MSFor years, we have been dedicated to providing comprehensive chemical solutions worldwide.
