Learn more about Retaining Compounds
Retaining compounds are a type of anaerobic adhesive essential for the precision assembly of interference and slip-fitting parts – and any component used within systems that are subject to high vibration in challenging environmental conditions. They fill spaces between individual components, cure to form a strong bond and allow for the transmission of high loads in the absence of air. This means sealed components and machine designs will achieve high strength and temperature resistance across a variety of substrates.
Retaining compounds are used in a broad range of mechanical components, as well as for bearings, shafts, and cylinder liners. They are most commonly found within the automotive and heavy machinery industries but can be used in any industry where metal-to-metal friction is required for load transfer. Retaining compounds help manufacturers avoid unnecessary machining of a broad range of mechanical components during MRO.
An excellent alternative to other mechanical methods, retaining compounds are ideal for any type of component that will be placed under stress, features a small adhesion area, or will be used within moving machinery. They are also suitable for components at risk of fretting and the consequent risk of corrosion as they can help reduce wear and potential failure during operation.
WHY CHOOSE LOCTITE® RETAINING COMPOUNDS?
Our range of high-strength retaining compounds offer unitized assembly, no fretting corrosion, uniform stress distribution, allows fitting of dissimilar metals, and helps you reduce costs. While retaining compounds are a similar product to threadlockers, they offer significant differences in performance. When comparing retaining compounds vs. threadlockers, it is important to know that threadlockers are designed to prevent loosening and leakage around threaded fasteners, whereas, retaining compounds offer a high strength bond when attaching non-threaded cylindrical components, and are especially useful in automotive or heavy machinery applications.
LOCTITE® retaining compounds are ideal for a wide range of industrial applications. In fact, they can be used wherever sealed cylindrical components require high strength bonding solutions.

FRETTING CORROSION PREVENTION
LOCTITE® bearing retaining compounds fill the air spaces between the two mated metal surfaces, which reduces fretting corrosion and oxidation, ensuring components run smoothly where high loads and repeated relative surface motion exist. Commonly this occurs in exposed metallic surfaces where long-term vibration is present, helping to mitigate mechanical wear that may cause metallic debris that undermines optimal operation.
LOCTITE® retaining compound solutions are found within a variety of general manufacturing applications thanks to their high versatility and broad spectrum of characteristics. Combined, this m means that a wide range of challenges can be met within facilities or the field, delivering reliable adhesion and strength in diverse environmental conditions across bearings, sleeves, and pins as well as close fit, slip fit, press fit, and shrink fit applications.
Industrial maintenance, repair, and operations programs require comprehensive solutions that aid optimal servicing and proactive repair. LOCTITE® retaining compounds ensure MRO teams can quickly and efficiently source targeted solutions to keep critical equipment in working order and ensure repairs are made when required.
Automotive retaining compounds from LOCTITE® deliver high-temperature resistance and gap filling solutions across a broad range of applications. Whether used within shaft or keyway repair to cut the costs of replacement or integrated into the design of electrical components, LOCTITE® retaining compounds are designed for seamless integration in automotive applications.
