It cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Typical applications include retention of bearings onto shafts and into housings.\u003c\/p\u003e\u003cul\u003e \u003cli\u003eFluorescent\u003c\/li\u003e \u003cli\u003eAllows disassembly for service operations\u003c\/li\u003e \u003cli\u003eDesigned for the bonding of cylindrical fitting parts\u003c\/li\u003e\n\u003c\/ul\u003eLOCTITE®\u003cbr\u003e672™ is designed for the bonding of cylindrical\u003cbr\u003efitting parts, particularly where disassembly is required for\u003cbr\u003eservice operations.

Although full functional strength is developed\u003cbr\u003ein a relatively short time, curing continues for at least 24 hours\u003cbr\u003ebefore full chemical\/solvent resistance is developed.\u003cbr\u003e\u003ch6\u003eCure Speed vs. Substrate\u003c\/h6\u003e\u003cbr\u003eThe rate of cure will depend on the substrate used. The table\u003cbr\u003ebelow shows the fixture time achieved on different materials\u003cbr\u003eat 22 °C \/ 50 % relative humidity. This is defined as the time to\u003cbr\u003edevelop a shear strength of 0.1 N\/mm².\u003cbr\u003e\u003ch6\u003eCure Speed vs. Bond Gap\u003c\/h6\u003e\u003cbr\u003eThe rate of cure will depend on the bondline gap.
