Henkel Loctite® 641 Controlled Strength Retaining Compound
Categories: Polymer; Adhesive; Thermoset

Material Notes:
Retainers
Loctite Corporation, the pioneer of anaerobic adhesives, has applied this technology to create retaining compounds that increase the shear strength of cylindrical, non-threaded assemblies. Finding wide acceptance as a standard method for assembling press and slip-fitted parts, Loctite® Retaining Compounds fill the "inner space" between components and cure to form a strong precision assembly. Formulated in a selection of viscosities, gap filling ability, flexibility and strength characteristics, Loctite® Retaining Compounds can be applied with automatic process equipment or dispensed manually.

Loctite® 641 Controlled Strength Retaining Compound
A controlled strength retaining compound that is ideal for cylindrical parts that require disassembly. Recommended for maximum diameter clearance of 0.008". Fixtures in 10 - 30 minutes.
Recommended Primer: 7649 (N).
Typical Use: Medium strength for removable bearings
