The product 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 the locking and sealing of large bolts and studs (M25 and larger). Cure Speed vs. Temperature The rate of cure will depend on the temperature.

For safe handling information on this product, consult the Safety Data Sheet (SDS). Where aqueous washing systems are used to clean the surfaces before bonding, it is important to check for compatibility of the washing solution with the adhesive. In some cases these aqueous washes can affect the cure and performance of the adhesive.

Users are recommended to confirm compatibility of the product with such substrates. Directions for use: For Assembly 1. For best results, clean all surfaces (external and internal) with a LOCTITE(R) cleaning solvent and allow to dry. 2. If the material is an inactive metal or the cure speed is too slow, spray all threads with Activator 7471TM or 7649TM and allow to dry. 3. To prevent the product from clogging in the nozzle, do not allow the tip to touch metal surfaces during application. 4. For Thru Holes, apply several drops of the product onto the bolt at the nut engagement area. 5. For Blind Holes, apply several drops of the product down the internal threads to the bottom of the hole. 6. For Sealing Applications, apply a 360 bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thouroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360 bead of product on the female threads also. 7. Assemble and tighten as required. For Disassembly 1. Apply localized heat to nut or bolt 250 C. Disassemble while hot. to approximately For Cleanup 1. Cured product can be removed by soaking in a Loctite(R) solvent, e.g. Loctite(R) 7200 and mechanical removal with Henkel Americas +860.571.5100 Henkel Europe +49.89.320800.1800 Henkel Asia Pacific +86.21.2891.8859 For the most direct access to local sales and technical support visit: www.henkel.com/industrial TDS LOCTITE(R) 272TM, December-2013 a soft scraper. Avoid formation of dust and aerosols. Complete the cleaning process by wiping with a soft cloth dampened with Loctite(R) Cleaner, e.g. Loctite(R) 7063 or Loctite(R) ODC-free cleaner.
