Anaerobic Adhesives

Anaerobic Adhesives are high-performance industrial bonding solutions specifically engineered to cure in the absence of air and in the presence of metal ions. They are widely used for locking, sealing, and retaining metal components, providing reliable, vibration-resistant bonds in demanding mechanical and industrial environments.

Thanks to their controlled curing mechanism and long-term durability, anaerobic adhesives are a trusted choice across automotive, manufacturing, and maintenance industries. Anaerobic adhesives are valued for their excellent resistance to vibration, shock, heat, oils, fuels, and industrial chemicals, ensuring secure assemblies under dynamic loads. Key features include controlled cure speed, high shear strength, gap-filling capability, corrosion protection, and long service life without loosening. Commercial grades are available for different functions, including threadlockers (low, medium, and high strength), retaining compounds, gasket sealants, pipe sealants, and flange sealants. These products are designed to bond and seal threaded fasteners, cylindrical parts, bearings, bushings, studs, gears, and flanges. Anaerobic adhesives eliminate the need for mechanical locking devices, reduce assembly time, and improve overall system reliability. Their liquid formulation allows easy application, uniform coverage, and precise dispensing, while curing only occurs once air is excluded between metal surfaces. Specialized grades are available for high-temperature resistance, fast curing, oil-tolerant surfaces, and service disassembly requirements.

Anaerobic adhesives are supplied in a wide range of commercial packaging to suit both maintenance and production needs, including small bottles, medium cartridges, bulk containers, and automated dispensing formats for assembly lines. Typical applications include automotive assembly, industrial machinery, pumps and valves, gearboxes, hydraulic systems, power tools, and general metal fabrication. With consistent performance, proven sealing efficiency, and compatibility with modern manufacturing processes, anaerobic adhesives remain a cost-effective and dependable solution for precision bonding, sealing, and locking in high-performance industrial applications worldwide.

FAQ Anaerobic Adhesives

Anaerobic adhesives are reactive adhesives that cure when they are confined between close-fitting surfaces and oxygen is excluded. They are particularly widely used for metal components and threaded assemblies.

They are commonly used for threadlocking, thread sealing, retaining cylindrical components and flange sealing. They help prevent loosening, leakage and movement caused by vibration and mechanical loads.

Yes. Anaerobic adhesives are primarily designed for metal-to-metal applications and are commonly used with steel, aluminum, copper and other metallic substrates. The appropriate grade depends on the specific metal and application.

Fixture time varies significantly by formulation and application. Some products can fixture within several minutes, while other high-strength grades may require considerably longer. Full cure generally takes longer than initial fixture.

Many cured anaerobic adhesives provide good resistance to temperature, oils, fuels, water and other industrial fluids. However, resistance depends on the specific formulation. Some high-temperature grades can withstand temperatures up to 232°C.

International buyers can use Irancorps to find Iranian suppliers of anaerobic adhesives. Irancorps helps buyers connect with Iranian suppliers through an internal supplier verification and KYC process and can help them compare available products and suppliers.
