Adhesives for Maintenance, Repair & Overhaul
Adhesives play a crucial role in the field of Maintenance, Repair, and Overhaul (MRO) by providing strong and reliable bonding solutions for a wide range of applications. From fixing components in aircraft to repairing machinery in industrial settings, adhesives offer numerous benefits that help streamline maintenance processes and ensure the longevity of equipment.
One of the key advantages of using adhesives in MRO activities is their ability to create bonds that are often stronger and more durable than traditional mechanical fastening methods. This is particularly important in industries where the reliability and safety of equipment are paramount. Adhesives can distribute stress evenly across bonded surfaces, reducing the risk of fatigue and failure over time.
Furthermore, adhesives provide a lightweight bonding solution, which can be critical in applications where weight reduction is a priority, such as in aerospace or automotive industries. By eliminating the need for heavy fasteners, adhesives can help improve fuel efficiency, increase payload capacity, and enhance overall performance.
In addition to their strength and weight-saving benefits, adhesives also offer advantages in terms of sealing and protection. Many adhesives are designed to create a barrier against moisture, chemicals, and other environmental factors that can cause corrosion or damage to equipment. This helps extend the lifespan of components and reduce the frequency of maintenance and repair tasks.
Overall, the use of adhesives in Maintenance, Repair, and Overhaul operations continues to grow as industries recognize the many advantages they offer in terms of strength, durability, weight savings, and protection. As technology advances and new adhesive formulations are developed, the role of adhesives in MRO activities is expected to expand even further, providing innovative solutions for the maintenance challenges of tomorrow.
Bonding with Cyanoacrylates
For bonding and repair jobs cyanoacrylate “instant” adhesives are a quick and effective option. They only take seconds to cure to handling strength and don’t require any sort of mixing, bonding most substrate materials. If you’re looking for ultimate high-strength bonding performance you could consider an 2-part epoxy or toughened adhesive, TA4246 is a structural acrylic which is going to offer rapid cure and excellent durability.
Threadlocking and Threadsealing
Threadlocking is a term used to describe the locking of threaded fasteners, utilisation of the process with adhesive compounds has many advantages such as helping to prevent potential injury, damaged goods and faulty or poor quality products.
Using adhesive thread sealing compounds can help prevent various issues such as flood damage, contamination, production line downtime, cleanup costs, personal injury, and the risk of fire or explosion.
The compound lubricates threads, making assembly easier, reduces the risk of cross-threading during assembly, prevents rust and corrosion for easier maintenance, and does not creep, shrink, or shred, ensuring valves are not blocked. It allows taps and valves to be easily aligned in the pipework system, can be used instead of PTFE tape or pipe dope, enables pipe joints to be re-used, is quick and easy to apply, suitable for a variety of pipe sizes, and has various approvals including KIWA Hydrogen.
Gasketing Adhesives- Anaerobic Sealing of Flanges
When it comes to sealing flanges, liquid gasket makers offer a convenient solution by filling all voids on metal surfaces and reducing the need for precise machining of flanges. They can be used as an alternative to pre-cut gaskets, simplifying inventory management with just one bottle needed for all gasket applications. These gasket makers are designed to be vibration-proof, ensuring that they will not loosen over time.
Unlike traditional gaskets, there is no need for a "bedding in" period or compression relaxation, which means no additional servicing is required. Additionally, liquid gasket makers provide better stress distribution, are easy to apply, and will not degrade, preventing loose particles from blocking valves. They also do not creep or shrink, making it easy to disassemble parts when needed. With 100% metal-to-metal contact, these adhesives fill all voids and create a much more effective seal for various applications.
Retaining- Securing Cylindrical Assemblies
When it comes to retaining adhesive selection for anaerobic securing of cylindrical assemblies, there are numerous advantages that make it a preferred choice over traditional methods. This adhesive effectively replaces keyways, splines, and the costly and time-consuming fine machining required for shrink or press fits. One of its key benefits is its vibration-proof nature, ensuring that the assembly does not loosen over time. The 100% metal-to-metal contact provided by this adhesive promotes better stress distribution and offers protection against metal fretting and corrosion.
Moreover, the adhesive is a single-part solution, eliminating the need for mixing and facilitating easy cleanup. Its ability to bond dissimilar metals allows for fast assembly, and the parts treated with this adhesive can be re-used without incurring damage. The application process is straightforward, with no design changes required as standard parts can still be used. Additionally, the adhesive enables relaxed machining tolerances, resulting in lower overall costs.
