Rust Inhibitor for Black Metals

Rust Inhibitors are oil‑soluble functional lubricant additives manufactured by Fanschem. Including thiazole, thiadiazole, amine‑based and carboxylic‑acid‑derived variants, these liquid‑state additives adsorb onto metallic surfaces to form dense isolating films that block moisture, oxygen and corrosive contaminants, effectively suppressing rust and electrochemical corrosion on ferrous and non‑ferrous metals. They feature favourable low‑temperature solubility, weak corrosiveness and splendid compatibility with extreme‑pressure agents, antioxidants and other lubricant additive packages. Widely applied in engine oils, gear lubricants, industrial greases, metal‑working fluids and long‑term equipment preservation oils, Fanschem supplies customizable‑performance grades to meet international anti‑corrosion specifications, with consistent bulk supply and dedicated formulation guidance for lubricant manufacturers across the globe.

What Are Rust Inhibitors

Rust Inhibitors are oil-soluble ashless corrosion prevention additives specially developed for ferrous and multi-metal systems, which form compact isolation films on metal surfaces to block moisture, oxygen and acidic substances and suppress oxidation rusting. Different from single-component simple anti-rust agents, Fanschem full rust inhibitor lineup covers seven mature industrial grades: CMET T703, CMET T747B, CMET AO, CMET SO, CMET T747A, CMET T711 and CMET T746. Each series adopts imidazoline, succinate and sarcosine molecular structures with strong metal adsorption capacity. After blending into base oil, they can build thin, uniform protective films without affecting the transparency of finished oil. With balanced acid neutralization, demulsification and dehydration functions, these rust inhibitors are widely recognized by global lubricant manufacturers for circulating industrial oils, metal working fluids, storage anti-rust oils and various lubricating grease formulas.

Core Performance & Key Features of Rust Inhibitors

Dense Protective Film & Long-Term Rust Prevention

All Fanschem rust inhibitors possess strong polar adsorption groups that tightly bind to steel, iron and alloy surfaces to form continuous waterproof barrier films. The isolation layer effectively resists humidity and salt mist erosion, realizing long-term indoor and outdoor anti-rust protection for workpieces and mechanical parts. CMET T703 and CMET AO deliver prominent acid neutralizing performance to eliminate acidic substances generated by base oil aging and further reduce metal corrosion risk. The thin film type CMET T711 will not produce thick sticky residues after long-term storage, keeping metal surfaces clean.

Multi-Functional Auxiliary Characteristics

The whole product line integrates multiple auxiliary properties beyond single rust resistance. CMET T746 has unique solubilizing ability for BTA metal passivators to simplify additive packages. CMET T747A and CMET T747B feature outstanding demulsification performance, quickly separating mixed water in circulating oil systems to avoid water-induced rust. CMET AO carries excellent dehydration and emulsifying capacity, suitable for water-containing metal processing media. CMET SO is copper non-corrosive and compatible with food-grade lubricant formulas with strict safety standards. All seven models are homogeneous transparent liquids with excellent miscibility with mineral oil, PAO and synthetic ester without sediment after low-temperature long-term storage.

Technical Advantages Over Ordinary Anti-Rust Additives

Compared with low-efficiency single carboxylic acid rust inhibitors, Fanschem multi-structure rust inhibitors have comprehensive competitive edges. Imidazoline and sarcosine molecules own much stronger metal adsorption force, offering far longer rust protection cycle under equal dosage. Most grades adopt low-acid ashless design, avoiding oil deterioration caused by high acid value additives. They possess built-in demulsification, dehydration and acid neutralization effects, removing the need to add separate auxiliary agents. The series shows good compatibility with EP/AW additives, metal deactivators and antioxidants without chemical reactions. They leave light, easy-to-clean protective films without sticky deposits, and lower recommended addition amounts effectively cut the total raw material cost for lubricant blending factories.

Main Applications of Lubricant Rust Inhibitors

Fanschem rust inhibitor series fits diverse lubricant and metal processing formulation scenarios. In industrial circulating oils such as hydraulic oil and compressor oil, they eliminate water and acid substances to prevent pipeline and equipment rust. In metal processing fields including cutting, drawing and stamping fluids, CMET AO and CMET SO balance rust prevention and processing lubricity. Various succinate grades are core raw materials for short-term and long-term metal storage anti-rust oils. All seven models can be compounded into lithium, composite and industrial greases to provide long-term anti-rust protection for bearings and gears. CMET SO is specially applicable to food contact machinery lubricants with strict non-ferrous metal protection requirements. The whole range works steadily for construction, mining, agricultural machinery and automotive lubrication systems exposed to humid environments.

Technical Specifications & Product Parameters
