Anaerobic adhesives, are also known as thread locking adhesives, are specialised adhesives that cure in the absence of air / Oxygen. These glues are used primarily in the manufacturing and maintenance of mechanical assemblies to securely fasten components together. Thread locking adhesives have become increasingly popular due to their ability to improve the overall strength and reliability of a joint, as well as prevent loosening caused by vibration or other external forces.

How do Anaerobic adhesives work?

Anaerobic adhesives work by filling the gaps between mating surfaces and curing in the absence of air. This creates a strong bond that prevents movement and keeps the components firmly locked together. The adhesive is typically applied to threaded fasteners, such as bolts and screws, but can also be used on other types of mechanical assemblies.

Can Anaerobic adhesives be used in wet environments?

Yes, some formulations of Anaerobic adhesives are designed for use in wet environments, such as those found in the marine industry.

Can Anaerobic adhesives be used on painted surfaces?

It’s generally not recommended to use Anaerobic adhesives on painted surfaces, as the adhesive may not bond properly to the paint. It’s best to apply the adhesive directly to the bare metal surface.

Can Anaerobic adhesives be used on plastic surfaces?

Yes, there are some formulations of Anaerobic adhesives that are specifically designed for use on plastic surfaces. However, it’s important to check the recommendations to ensure that the adhesive is compatible with the specific type of plastic.

Can Anaerobic adhesives be used for gap filling?

No, Anaerobic adhesives are not designed for gap filling. They require close-fitting surfaces to create a strong bond.

Can Anaerobic adhesives be used on Aluminium surfaces?

Yes, certain Anaerobic adhesives have been designed for use on Aluminium surfaces; however, it’s important to check the recommendations to ensure that the adhesive is compatible with the specific type of Aluminium.

Can Anaerobic adhesives be used on stainless steel surfaces?

Yes, Anaerobic adhesives can be used on stainless steel surfaces. However, it’s important to choose a formulation that is specifically designed for use on stainless steel to ensure a strong bond.

Benefits of Anaerobic adhesives

There are several benefits to using Anaerobic adhesives in mechanical assemblies, including:

Improved strength

Thread locking adhesives create a strong bond that prevents loosening caused by vibration or other external forces. This improves the overall strength and reliability of the joint.

Corrosion resistance

Anaerobic adhesives are resistant to corrosion, which is a common problem in metal-to-metal joints. This helps to extend the life of the joint and prevent costly repairs.

Reduced assembly time

Thread locking adhesives cure quickly, which reduces assembly time and allows for faster production.

Easy disassembly

While thread locking adhesives create a strong bond, they are also designed to be easily disassembled when necessary. This allows for repairs and maintenance to be performed without damaging the components.

Application uses for Anaerobic adhesives

Thread locking adhesives have a wide range of applications in the manufacturing and maintenance of mechanical assemblies. Some common applications include:

Automotive

Thread locking adhesives are used in the assembly of engines, transmissions, and other critical components in vehicles.

Aerospace

Thread locking adhesives are used in the assembly of aircraft engines, landing gear, and other critical components in the aerospace industry.

Industrial machinery

Thread locking adhesives are used in the assembly of heavy machinery, such as pumps, motors, and gearboxes.

Construction

Thread locking adhesives are used in the construction of bridges, buildings, and other infrastructure projects.

What types of surfaces can Anaerobic adhesives be used on?

Anaerobic adhesives are typically used on metal surfaces, although some formulations can also be used on plastics and other materials.

How long does it take for Anaerobic adhesives to cure?

The cure time for Anaerobic adhesives can vary depending on the formulation, but it typically ranges from a few minutes to several hours.

Can Anaerobic adhesives be used in high-temperature applications?

Yes, there are Anaerobic adhesives that are specifically designed for high-temperature applications, such as those found in the automotive and aerospace industries.

Are there any safety precautions I should take when using Anaerobic adhesives?

Yes, it’s important to follow the safety guidelines when using Anaerobic adhesives, including wearing gloves and protective eyewear, and ensuring adequate ventilation in the workspace.

How do I remove Anaerobic adhesives?

Anaerobic adhesives can be removed using heat or solvents that are specifically designed for that purpose. It’s important to follow the instructions when removing the adhesive to avoid damaging the components.

Can Anaerobic adhesives be used on non-threaded fasteners?

Yes, there are Anaerobic adhesives that are specifically designed for use on non-threaded fasteners, such as keyways and splines.
