Dimer acid
Dimer acid from Anqing Hongyu Chemical Co., Ltd. is a C36 carboxylic acid derived from the dimerization of unsaturated fatty acids, typically from tall oil or vegetable oils. It has a melting point range of 65 to 75 degrees Celsius and a viscosity of 150 to 300 mPa·s at 120°C, enabling smooth processing in high-temperature formulations. The product is non-toxic and non-irritating, with a flash point above 250°C, reducing fire risk during storage and transport.
This material is typically composed of 90% or greater dimer acid content, with monomer and trimer acids below 5% each, consistent with industry standards for polymer-grade dimer acid. It exhibits low water solubility and remains stable under ambient conditions, making it suitable for long-term storage. The acid does not crystallize below 0°C, a key advantage in cold-climate logistics. No synthetic additives or stabilizers are reported in the source data.
It is primarily used in polyamide hot-melt adhesives, lubricant thickeners, and alkyd resins for coatings. Buyers include manufacturers in the automotive, construction, and personal care sectors requiring consistent viscosity and thermal stability. Packaging is in 25kg woven polypropylene bags with inner liners. Trade terms offered are FOB or CIF from Chinese ports, with MOQ negotiable based on container volume.

Sourcing Dimer acid from Anqing Hongyu Chemical Co., Ltd. - China Import Guide
Before ordering, verify the dimer acid’s acid value, iodine value, and monomer/trimer content via a recent certificate of analysis. Confirm the melting point range matches your application’s processing temperature. Request batch-specific GC data to ensure consistency with prior shipments. Do not rely on supplier claims without documentation.
Confirm the Incoterms agreed upon - FOB or CIF - and whether the supplier handles export customs clearance. Lead time is typically 15 to 25 days after order confirmation, but this is not guaranteed. Payment terms are usually T/T or L/C; request a pro forma invoice with full product specifications before payment. Ensure the container is sealed and labeled with the batch number upon loading.
Inspect each batch for color consistency, absence of crystallization, and packaging integrity. Request a moisture content test (Karl Fischer) if used in moisture-sensitive formulations. Retain a sample from each shipment for future quality comparison. Ensure the supplier provides a safety data sheet compliant with GHS standards and a declaration of conformity for your region’s chemical regulations.
