Ammonium carboxylate rust inhibitors formed by the reaction of dodecanedioic acid with amines exhibit extremely strong rust prevention effects in metalworking fluids. Even at very low concentrations, they significantly inhibit the rusting of iron and protect metal surfaces from corrosion. This type of rust inhibitor forms a dense passivation layer on the metal surface, effectively blocking direct contact between corrosive media and the metal, thereby extending the metal's service life.

Dodecanedioic acid and the ammonium carboxylate rust inhibitors it produces are non-toxic to humans and are biodegradable in nature, meeting the requirements of environmental protection and sustainable development.
These characteristics give dodecanedioic acid broad application prospects in fields such as metalworking fluids, coatings, rust preventive oils, and rust preventive paper, and it maintains stable rust prevention effects over long-term use.
Dodecanedioic acid is primarily produced through chemical synthesis or biological fermentation methods. Chemical synthesis typically involves a series of chemical reactions, extracting raw materials from fossil fuels such as petroleum or natural gas, and synthesizing dodecanedioic acid through multiple steps. Biological fermentation, on the other hand, utilizes microbial metabolic activities to convert renewable resources like glucose into dodecanedioic acid.


The dodecanedioic acid supplied by our company is produced by Japan's UBE Corporation, primarily used in copolyamide hot melt adhesives, long-chain nylons, cutting fluids, powder coatings, fragrances, and polyurethanes. UBE Corporation uses chemical synthesis to produce dodecanedioic acid, which offers good stability, high purity, no residual active microorganisms, and superior durability in use.


The original Japanese UBE imports come in 20KG paper bags, 1000KG per pallet, promoting the widespread use value of UBE's synthetic dodecanedioic acid. Additionally, U.S.-based Invista also produces dodecanedioic acid through synthesis, but it is gradually losing the Chinese market due to its high price. Supplying high-quality dodecanedioic acid at an affordable price requires more concessions, and our company is committed to providing dodecanedioic acid at a reasonable price.
