Rayhong 271 Threadlocker is an industrial-grade, high-strength thread fixing solution designed for bolts, nuts and other metal fasteners in mechanical vibration environments.
Adopting modified acrylate formula, it realizes permanent locking between metal threads through chemical reaction, and can withstand destructive torque of more than 50Nm, completely solving the problem of loosening and falling off caused by long-term operation of equipment, and it is a professional choice in the fields of machinery manufacturing, automotive maintenance and aerospace.
Core Technology
1. Triple reaction formula
Acrylate monomer: penetrate the thread gap to form polymer.
Auxiliary accelerator: accelerates the activation reaction on the metal surface.
Anaerobic initiator: triggers curing in an oxygen-free environment.
2. Military grade performance
√ Temperature range: -54℃ to 149℃.
√ Vibration Resistance: Passed MIL-S-22473E standard test.
√ Sealability: can replace the traditional gasket, anti-leakage pressure up to 30bar.
3. Intelligent curing characteristics
Initial cure 20 minutes to withstand normal loads.
After 24 hours of full cure, it needs to be heated up to 260℃ before dismantling.
Operating Instructions
Surface preparation: Oil removal with Rathong 747 cleaner (critical step)
Dispensing process:
Small threads (below M6): 1-2 drops to the end of the bolt
Large threads (M6 and above): apply to the full face of the external threads.
Assembly fastening: tighten according to standard torque
Curing management:
Light load after 20 minutes
Full load after 24 hours
