 Applications 

1. Paint, Ink & Coating Driers — cobalt, manganese, zirconium, calcium and zinc octoates, solvent-borne and water-borne alkyds: The acid behind every metal drier. Its branched structure keeps the metal carboxylate soluble in hydrocarbon and solvent systems, so the drier disperses evenly and catalyses the oxidative crosslinking that turns an alkyd film hard.

2. PVC Heat Stabilisers — Ca/Zn stabiliser systems, co-stabilisers, Plastisol and rigid PVC: Converts to the metal carboxylate that scavenges hydrogen chloride as PVC breaks down in the extruder. The branched chain improves compatibility with the polymer and reduces plate-out.

3. Polyurethane, Silicone & Esterification Catalysts — tin and zinc octoates, moisture-cure silicone, condensation reactions: Stannous and zinc 2-ethylhexanoate are standard catalysts for PU foams, coatings and RTV silicones, where the carboxylate ligand controls both activity and shelf stability. Also used as a mild esterification catalyst in polyester and alkyd production.

4. Lubricants, Greases & Metalworking Fluids — corrosion inhibitors, friction modifiers, grease thickener soaps: Its metal salts provide oil-soluble corrosion protection and boundary lubrication, and the acid itself is a building block for ashless additives. Well suited to formulations that must stay clear and stable in hydrocarbon base oils.

5. Synthetic Ester Base Stocks & Plasticisers — polyol esters, aviation and refrigeration lubricants, ester plasticisers: Esterification with polyols and glycols gives esters with high thermal stability, low volatility and good low-temperature flow. Used to build lubricants for compressors, turbines and refrigeration systems, and plasticisers for PVC and cellulosics.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
