Supex Anaerobic threadlockers
Why are threadlockers required? Mechanical locking devices , Eg: split ring washers, nylon insert nuts, and serrated tooth washers are used to solve the common problem of loosening that happens in most threaded assemblies. However, the reality is that they don’t “lock” the assemblies and can’t maintain clamp load. These devices often loosen under vibration, thermal expansion, bending, and/or improper torque.
Threadlockers, or threadlocking adhesives, are the solution to this problem. Applied between two mating threads, these liquid threadlocker adhesives secure nuts, bolts, and threaded fasteners in place. They cure to form a strong bond that prevents loosening, ensuring assemblies retain clamp load over time.
Threaded fasteners, such as bolts and nuts, have a huge role to play in many industries. Their impressive clamp load means they are the ideal fastener for use across a wide range of manufacturing and maintenance applications. However, these types of assemblies can fail over time as they work themselves loose, thanks to vibration, bending, or thermal expansion.
Advantages of using Supex threadlockers
threadlockers are products you can trust for securing threaded fasteners in place. They offer versatility, affordability, and reliability in your assemblies.
Threadlocking compounds can effectively reduce the impact of costly failures, repairs, maintenance, and downtime. Applied to one or two threads before assembly, Threadlockers push the air between the threads out as the fastener is tightened. The anaerobic threadlocker material cures in the absence of air to form a strong, thermoset plastic that locks threads and joints in place.
Supex threadlockers can also lower the effect of corrosion in threaded components and help to prevent leaks in your assemblies. Applicable across both maintenance, repair, and operations and original equipment manufacturing. Supex threadlockers improve reliability, eliminate failure, and boost productivity in your operations.
APPLICATION TEMPERATURE:+5 ℃ to +45 ℃
1. For best results, the surface of the material to be bonded should be clean and free of grease.
2. To ensure fast and reliable curing, one bonding surface is coated with activator and the other surface is coated with glue. The parts
should be assembled immediately within 15 minutes.
3. It is recommended that the gap between the adhesive layer is 0.1mm. When the gap of the glue layer is too large (≤0.5mm) or fast
curing is required, an accelerator can be used. The components must be assembled quickly within one minute.
4. Excess adhesive can be removed with organic solvents.
5. The bonded parts should be fixed until the adhesive is initially set.
6. After the adhesive has reached full strength, it can bear the load (full curing time is between 24 and 72 hours)

What are Threadlockers?
Threadlockers is a single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion.
Most thread-locking formulas are methacrylate-based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid is thixotropic, which allows it to flow well over time, yet still resist shocks and vibrations. It can be permanent or removable; in the latter case, it may be removable merely by force or may also require heating, for example. Typically, brands are color-coded to indicate strength and whether they can be removed easily or require heat for removal.
Applications
Thread-locking fluid may be applied before or after assembly, depending on the type. Threadlockers are available in varieties of “permanent”, “removable”, and “low-strength” formulas. Many brands color-code the container and the fluid itself to indicate the degree of permanency. The low-strength types prevent loosening under vibration, but may still be readily disassembled. Removable types resist higher amounts of vibration, but may still be disassembled with hand or power tools. The strongest permanent threadlockers require high applied torque to loosen a permanently threadlocked fastener may exceed the yield strength of the fastener itself, such that attempting disassembly by force may twist off the stem of the fastener. However, high-strength permanent threadlockers become potentially removable by heating the assembly, typically to 230 °C.
Working temperatures for threadlocked fasteners are typically limited to 150 °C , which is below the softening point of the methacrylate polymer. Above this temperature, the material softens and strength reduces.
Because thread locking adhesives typically rely on the electrochemical activity of a metal substrate to form a bond, surfaces must be clean to develop the full bonding strength. In the case of less electrochemically active metals such as the normally oxidised surface of aluminium, an additional step of priming is required for full strength results. washers, locknuts, jam nuts may be used in conjunction with thread-locking fluid to prevent loosening of bolted joints.
Because electrochemical activity is one of the two triggers that cause polymerization of the threadlocker fluid, care must be taken to avoid contaminating the entire threadlocker container with threadlocker that has had contact with metal, or the material in the container may polymerize.
