Retaining Compound vs Threadlocker: Key Differences
Retaining Compounds Overview
Retaining compounds play a crucial role in various industrial applications by providing strong, high-precision bonds between mechanical components. Here’s an overview of their function and the key benefits they offer.
Function of Retaining Compounds
Retaining compounds are anaerobic adhesives specifically designed to fill gaps and spaces between mechanical parts to secure them firmly in place. Introduced in the 1960s, these compounds are commonly used in installing bearings inside housings, shafts, and retaining cylinder liners (Gluegun.com). Here’s a look at how retaining compounds function:
- Filling Spaces: They fill the voids between components, ensuring that parts sit flush against each other.
- Axial and Radial Strength: By bonding parts together, these compounds significantly enhance the axial and radial strength of the assembly.
- Prevention of Movement: They reduce unwanted movement and rotation, thereby preventing wear and potential failure of the component assembly.
- Curing Process: These compounds cure in the absence of air (anaerobic conditions) to form a durable, high-strength bond with the metal surfaces, ensuring stability even under high loads and vibrations.
Benefits of Retaining Compounds
The use of retaining compounds offers several advantages, especially in environments where precision and strength are paramount. Below are some of the primary benefits:
- Increased Axial Strength: Applying a retaining compound at the joint can increase the axial strength of a component by up to three times, preventing potential damage to the system (Gluegun.com).
- Versatility: Beyond bearings, retaining compounds can be used to secure gears and pulleys to shafts, fix oil filler tubes in castings, retain cylinder liners, and restore the accuracy of worn machine tools (Gluegun.com).
- High Load Transmission: Retaining compounds enable high-load transmission without the use of air, preventing part deterioration over time.
- Customization: Different types of retaining compounds are available based on specific needs, such as high strength, gap-filling abilities, or faster curing speeds, making them suitable for a variety of applications and requirements (Gluegun.com).

Types of Threadlockers
Threadlockers are an essential component in maintaining the integrity of threaded assemblies. Incorrect selection can have a significant impact on the performance and reliability of these assemblies.
Impact of Choosing the Wrong Threadlocker
Selecting the wrong type of threadlocker can lead to several issues such as reduced reliability, difficulties with removal, and improper curing. This may impact how well the adhesive locks assemblies in place, increasing the chance of loosening and eventual failure.
Common issues include:
- Reduced Reliability: The adhesive may not hold as expected, leading to potential loosening over time.
- Difficulties with Removal: If a high-strength threadlocker is used where a low-strength one is required, removing the fasteners can become a challenging task.
- Improper Curing: The threadlocker may not cure correctly if the wrong type is chosen, impacting its effectiveness.
