In the world of manufacturing and equipment maintenance, the order of operations is critical. While most threadlockersare applied to fasteners before they are assembled, there are countless scenarios where an assembly has already been completed, torqued, or is in the field, and a secure lock is needed without disassembly. For these unique challenges, a standard adhesive simply won’t work.

This is the domain of wicking grade threadlocker. Its specialized, low-viscosity formulation allows it to penetrate into the microscopic gaps of an already assembled joint, providing a secure lock and seal without ever having to touch a wrench. For engineers and field technicians, a wicking threadlocker is an invaluable tool for post-assembly security and preventive maintenance.

What is Wicking Grade Threadlocker? The Post-Assembly Solution

Wicking grade threadlocker is a unique type of anaerobic adhesive distinguished by its extremely low viscosity, similar to that of water. This property is its key feature: it allows the liquid to flow by capillary action into the minute spaces between the threads of a nut and bolt that are already tightened.

This “wicking” action provides a number of critical benefits:

• Post-Assembly Application: It allows a technician to secure a fastener after assembly, saving valuable time and effort by eliminating the need to disassemble and re-torque.
• Sealing Porous Metals: Its low viscosity also makes it highly effective for sealing hairline cracks and porosity in metal castings and welds, providing protection against fluid leaks.
• Corrosion Protection: By filling the voids, it protects the threads from rust and corrosion, extending the life of the fastener.

Key Applications for Wicking Threadlocker

The versatility and ease of application of wicking threadlocker make it ideal for a variety of specific use cases in manufacturing and field service.

• Electronics & Small Assemblies: Securing micro-fasteners in circuit boards, instrument housings, and other tight spaces where disassembly is difficult or undesirable.
• Preventive Maintenance: Applying it to existing, non-locked fasteners in the field to prevent them from loosening due to vibration and shock.
• Calibration & Adjustment: Locking fasteners on a component that has been precisely adjusted, without having to risk moving the component during disassembly and re-assembly.
• Sealing Welds & Castings: It is used to quickly and effectively seal porosity in welds and small cracks in metal castings, preventing leaks in fluid systems.

The Incure Re-Lok™ B90 Advantage: A Wicking Grade Threadlocker for Versatility

For professionals, choosing a high-quality wicking-grade adhesive is essential. The Incure Re-Lok™ series is engineered with precision and versatility in mind.

• Incure Re-Lok™ B90 Green Threadlocking Adhesive is a medium-strength, low-viscosity wicking adhesive designed for locking and sealing pre-assembled bolts from M2 to M12. Its medium strength provides a reliable lock that resists vibration, yet the bond can be disassembled with heat and hand tools if required.
• Dual Functionality: Re-Lok™ B90 is a powerful two-in-one product. In addition to securing pre-assembled fasteners, it is also ideal for sealing porous metal parts, offering a cost-effective and efficient solution for a variety of sealing needs.
• Fast Curing: With an initial cure time of just 20 minutes, Re-Lok™ B90 allows for quick assembly and a fast return to service.
• Prevents Rust and Corrosion: The cured adhesive provides an excellent seal that protects the threaded fasteners and porous metals from environmental degradation.

Practical Insights & Actionable Advice

• Clean the Joint: For the best wicking action, ensure the joint where the adhesive is applied is clean and free of heavy grease or debris. This allows the liquid to flow into the threads effectively.
• Apply Liberally: Apply a generous amount of the adhesive around the joint of the nut and bolt head. The capillary action will draw it into the threads.
• Understand the Strength: Re-Lok™ B90 is a medium-strength adhesive. For permanent, high-strength applications, a high-strength red threadlocker should be used before assembly.
