Import Dimer Acid — Buy in Bulk from Supplier in China

Dimer acid from Shandon Huijin Chemical Co., Ltd. is a refined grade produced by reducing trace impurities in conventional dimer acid using advanced separation technology. The product is designed specifically for high-grade epoxy curing agents and polyamide resin applications where purity and consistency are critical. It appears as a light yellow viscous liquid with no visible particulates and is processed to minimize residual monomers and color bodies.

The material is derived from hydrogenated tall oil fatty acids and undergoes molecular distillation to remove low-boiling contaminants. This results in a product with enhanced thermal stability and lower color index compared to standard dimer acid. The typical acid value is 185 to 195 mg KOH/g, and moisture content is controlled below 0.3%. Packaging options include 190kg plastic drums, 950kg IBC totes, and 20-ton tankers or flexitanks for bulk orders.

This grade is selected by manufacturers producing high-performance adhesives, powder coatings, and specialty polyamides where color stability and low volatility are required. Buyers include chemical formulators in automotive, electronics, and industrial coatings sectors. The product is not marketed for food or pharmaceutical use. Trade terms are FOB Qingdao or CIF, with lead times of 10 to 18 days depending on packaging type and order volume.
