How to use it
1. Preparation - Cleaning
It is recommended to use LOCTITE® SF 7063/7064 to degrease and clean surfaces prior to applying adhesive.
2. Preparation - Activation
If cure speed is too slow due to passive metals (stainless steel, aluminium and plated metals) or low temperature (below 5°C), use activator LOCTITE® SF 7240 or LOCTITE® SF 7649 (see cure speed vs activator graph in the TDS).
3. Application
Apply liquid threadlocker to the engagement area. For manual dispensing the use of a peristaltic handgun is recommended to ensure a consistent application volume.
4a. Application - Through Hole
Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.
4b. Application - Blind Hole
Apply into lower third of blind hole.
5. Assembly
Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
6. Disassembly - Hand Tools
Disassemble with standard hand tools.
7a. Disassembly - Heat
If disassembly is not possible using normal hand tools, apply localised heat to approximately 250°C. Disassemble while hot.
7b. Disassembly After Heating - Hand Tools
Disassemble while hot with standard hand tools.
Hint
For the disassembly of corroded or seized parts, use LOCTITE® LB 8040 Freeze and Release.
Technical and safety documents
When you need to permanently lock assemblies that must not come loose, LOCTITE® 270 is a great choice. This high-strength threadlocker delivers maximum efficacy in securing and sealing bolts, nuts and studs to prevent loosening due to shock and vibration. It works on all metals without the need for a surface activator or primer – including passive substrates like stainless steel, aluminium and plated surfaces – and can cure through light coatings of corrosion-prevention oils and cutting fluids without needing to clean the surfaces prior to application. The lock might be permanent, but it can still be disassembled: simply heat to 300°C (572°F) and remove while still hot.
