High-strength retaining compound for steel

Loctite 135516 is a green dimethacrylate liquid formulated to bond cylindrical steel parts with high shear strength. It fills gaps up to 0.015 inches and reaches full cure in one day, making it suitable for permanent assemblies that must resist vibration and shock.

Thermal stability and clean-up requirements

The compound operates continuously from minus 65 to 400 degrees Fahrenheit without degrading. A primer is required before application, and any excess or spillage must be removed using solvent and a wire brush before the adhesive sets.

Maximum gap fill of 0.015 inches decides fit

This single dimension determines whether the product will work for a given joint; gaps larger than 0.015 inches cannot be reliably filled. Buyers needing to bridge wider clearances should select a different grade.

Questions about this item

How do I apply the retaining compound and what step is commonly missed?

Apply directly from the 50ml bottle to the steel surfaces, ensuring the gap does not exceed 0.015 in. The step often missed is using a primer, which is required for this compound to cure properly.

What maintenance or replacement will this bond need over time?

Once fully cured after 1 day, the bond achieves 4,495 psi shear strength and is designed to be permanent. No routine maintenance is required; replacement would only be necessary if the assembly is disassembled using heat and force.

What is the first limit reached under sustained high-temperature operation?

The maximum operating temperature is 400 Degrees F. Sustained exposure beyond this limit will degrade the dimethacrylate chemical base and cause the bond to fail before the minimum temperature of -65 Degrees F becomes a factor.
