Loctite 641 Retaining Compound 50 ML

LOCTITE®
641 is designed for the bonding of cylindrical fitting
parts, particularly where disassembly is required for service
operationsThe product cures when confined in the absence of
air between close fitting metal surfaces and prevents loosening
and leakage from shock and vibrationTypical applications
include retention of bearings onto shafts and into housings

TYPICAL CURING PERFORMANCE
Cure Speed vs. Substrate
The rate of cure will depend on the substrate usedThe graph
below shows the shear strength developed with time on steel
pins and collars compared to different materials and tested
according to ISO 10123
