Thread securing compounds with 30 minute dry time, 24hour full cure \n Purple: lowstrength for smaller fasteners. Can be separated using hand tools (good spoke prep) \n Blue: general/mediumstrength "removable" thread locker for most bicycle applications. Can be separated using hand tools (also offered in 'oilresistant' formula for use on nonprimered surfaces) \n Red: permanent/highstrength threadlocker for most bicycle applications. Can be separated using hand tools and directed +300Fdegree heat source \n Green: designed for cylindrical parts bonding (e.g. cartridge bearing to pivotaxle) highstrength yield = usually requires +300Fdegree heat source and tools for removal (should not be used on commonly adjusted fasteners, this compound should be viewed as a permanent set)
