Loctite® 641 is designed for the collage of cylindrical assemblies, particularly suitable for parts requiring regular disassembly for maintenance. The product polymerizes when it is confined in the absence of air between metallic surfaces with a low game. It has the function of preventing loosening and leaks due to shocks and vibrations. Recommended for the fixing of parts which must be dismantled, for example the bearings mounted on their tree and in their accommodation.
