Loctite retaining compounds secure bearings, bushes and cylindrical parts into housings or onto shafts. They achieve load transmission capability and uniform stress distribution, and eliminate fretting corrosion. Applied as a liquid, they form 100% contact between mating metal surfaces, helping with time and financial costs. They fill the inner space between compounds and cure to form a strong precision assembly. Browse their full range below.

For gaps up to 0.15 mm, lower viscosity retaining compounds are suitable, often used for tight-fitting interference fits like press and shrink fits. Gaps between 0.15 to 0.25 mm require retaining compounds with higher viscosities to allow better gap fill, including bonded slip fits. Assemblies with larger gaps, typically between 0.25 to 0.5 mm, may need special paste-like compounds, especially for worn parts.
Most Loctite retaining compounds are able to withstand temperatures of -55 to 150 °C. However, certain chemistries are available that withstand temperatures up to 180 to 230 °C for assemblies which see higher service temperatures.
Applied as a liquid, retaining compounds fill surface irregularities and provide 100% contact between mating metal surfaces, eliminating the need for expensive replacement parts, time consuming machining, or the use of mechanical methods. In addition, retaining compounds offer high strength with simplified and less costly designs, and reduced dependence on machining tolerances. They eliminate corrosion and fretting, and improve the durability of assembly. They offer the ability to disassemble the component, and an even distribution of load and stress over the entire joint.
Retaining compounds, unlike threadlockers, are typically higher strength and designed specifically for bonding cylindrical components that must resist usually torque and compressive loads.
