Organic corrosion inhibitors are increasingly used in industrial applications in recent years in place of inorganic corrosion inhibitors. Long-chain dicarboxylic acids are a group of anti-corrosion additives that can inhibit corrosion efficiently at low concentrations and are non-toxic and biodegradable. Dibasci acids are used as corrosion inhibitors in metal working fluids, metal cleaners, engine coolants, aqueous hydraulic fluids and diecast release agents, protecting metal working parts and coolant systems from rust. Our DC11 to DC14 can be used in the production of corrosion inhibitors.

Our Long-chain dicarboxylic acids function as organic corrosion inhibitors via chemisorption on metal surfaces (Fe, Cu, Al) to form a dense, protective carboxylate film that blocks oxygen, water, and corrosive ions.
- Key Products: Sodium/potassium salts of LCDAs, amide derivatives, esterified inhibitors.
- Technical Advantages: Multi-metal compatibility, low toxicity vs inorganic inhibitors (chromates, nitrites), good thermal stability, synergistic effects with other additives (triazoles, phosphates).
- End Uses: Metalworking fluids (cutting, grinding oils), engine coolants (antifreeze), industrial water treatment (cooling towers, boiler systems), metal surface pre-treatment.
