Hướng dẫn sử dụng Loctite 271

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.

4. Application - Through Hole

Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.

5. Application - Blind Hole

Apply into lower third of blind hole.

6. Assembly

Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.

7. Disassembly - Hand Tools

Disassemble with standard hand tools.

8. Disassembly - Heat

If disassembly is not possible using normal hand tools, apply localized heat to approximately 250°C. Disassemble while hot.

9. Disassembly After Heating - Hand Tools

Disassemble while hot with standard hand tools.

10. Hint

For the disassembly of corroded or seized parts, use LOCTITE® LB 8040 Freeze and Release.
