Import Dimer Acid — Buy in Bulk from Supplier in China

Dimer Acid from Shandong Huijin Chemical Co., Ltd is a light yellow, transparent thick liquid derived from the dimerization of unsaturated fatty acids, typically from tall oil or vegetable oils. It has a high flash point above 200°C and exhibits low volatility, making it suitable for industrial processes requiring thermal stability. The product is non-toxic and chemically inert under standard conditions, with an acid value ranging between 180 and 200 mg KOH/g as confirmed by standard titration methods.

This material is typically composed of C36 dicarboxylic acids with a branched aliphatic backbone, which contributes to its low crystallinity and good solubility in organic solvents. It is commonly available in grades meeting ASTM D2794 or ISO 15543 standards for purity and consistency. Industry-standard impurity limits include moisture content below 0.5% and color not exceeding 50 APHA, though exact values depend on batch processing. The absence of heavy metals and halogens aligns with general industrial chemical safety benchmarks.

It is primarily used as a curing agent in epoxy resins, a modifier in polyamide hot-melt adhesives, and an emulsifier in waterborne coatings. Buyers include manufacturers of industrial adhesives, powder coatings, and personal care formulations requiring stable rheological properties. Packaging is in 190kg plastic drums or 20-ton bulk tanks. Trade terms are typically FOB Qingdao or CIF destination, with MOQs negotiable based on volume. Lead times are approximately 15 to 20 days after order confirmation, subject to production scheduling.
