The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. LOCTITE® 680™ provides robust curing performance. It not only works on active metals (e.g. mild steel) but also on passive substrates such as stainless steel and plated surfaces. The product offers high temperature performance and oil tolerance. It tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids.  \nThis Technical Data Sheet is valid for LOCTITE® 680™ manufactured from the dates outlined in the\"Manufacturing Date Reference\" section.  \nNSF International  \nCertified to ANSI/NSF Standard 61 for use in commercial and residential potable water systems not exceeding 82° C. Note: This is a regional approval. Please contact your local Technical Service Center for more information and clarification.  \nTYPICAL PROPERTIES OF UNCURED MATERIAL  \nSpecific Gravity @ 25 °C 1.1  \nViscosity, Brookfield-RVT, 25 °C, mPa·s (cP):  \nSpindle 3 , speed 20 rpm 750 to 1,750LMS  \nViscosity, Cone & Plate, 25 °C, mPa·s (cP):  \nShear rate 129 s-1 650 to 1,850  \nFlash Point-See SDS  \nTYPICAL CURING PERFORMANCE  \nCure Speed vs. Substrate  \nThe rate of cure will depend on the substrate used.
