Product Information

R38 Retainer

Lockfast R38 Retainer


Lockfast R38 Retainer is a green, high-strength, high-viscosity retainer for bonding cylindrical fitted parts where ultimate strength is required, typically in power transmission environments.  Ideal for bond gaps up to 0.25mm. Uses can include locking of bushes and sleeves into housings.  Works with active (mild) steel and passive metals (plated metals e.g stainless steel).  Tolerant to minor contaminants such as oils, making it ideal for shafts, gears and pulleys. Will prevent leakages and loosening from vibration and shock.  UV fluorescent properties allow the products presence to be monitored in quality control via a UV black light.


Directions For Use


1. For optimum performance surfaces should be clean and free of grease.

2. If the material is an inactive metal consider using activator.

3. Shake the product thoroughly before use. Apply several drops to parts to be bonded.

4. Assemble as required. (see the Lockfast retainer technical information sheet for further information on types of application).

5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.


Fixture Time vs. Substrate


There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.

For more information on strength of bond and cure time, please see the Lockfast retainer technical information sheet.


Disassembly and Clean-up


Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
