Anaerobic Threadlocker CX80 RC43 10 ml — medium strength, blue

CX80 RC43 is an anaerobic threadlocker supplied in a 10 ml bottle, formulated for medium strength bonding of threaded fasteners. The blue compound cures when confined between metal surfaces in the absence of air to form a durable polymer that resists vibration-induced loosening and provides protection against corrosion. It is designed for applications where a removable but secure fastening is required, including machinery, automotive assemblies and general maintenance tasks.

Advantages

The medium-strength formula provides reliable locking of bolts, nuts and studs while allowing disassembly with standard hand tools when required. Its anaerobic curing ensures rapid polymerisation on metal surfaces and good gap-filling capability for close-fitting threads. The product reduces fretting and galvanic corrosion at the joint and delivers consistent performance across a range of temperatures and common engineering metals.

Suitable for

• Locking and sealing threaded fasteners in machinery and equipment
• Automotive assembly and repair of bolts, studs and wheel components where removable locking is needed
• General maintenance tasks in industrial and workshop settings
• Applications requiring vibration resistance and protection against corrosion

Key specifications

• Form: liquid anaerobic adhesive, blue
• Volume: 10 ml bottle
• Strength class: medium strength threadlocker suitable for removable fastenings
• Curing mechanism: anaerobic cure when confined between metal surfaces
• Application surfaces: designed for use on metal threaded assemblies

How to use

Ensure mating threads are clean, dry and free of oils, grease and loose rust before application. Apply a few drops of CX80 RC43 onto the threads, concentrating on the nut-facing side for best distribution. Assemble the fastener and allow the adhesive to cure undisturbed; initial handling strength develops quickly, with full cure achieved depending on gap size, metal substrate and temperature. Disassembly can be performed with standard hand tools when required.

Usage recommendations

For optimal results, clean threads with an appropriate solvent or wire brush and avoid over-application. Store the bottle capped in a cool, dry place away from direct sunlight. When working with plated or passive surfaces, consider using an activator or test cure to confirm adequate bonding. Follow all safety and handling instructions provided on the product label.
