Hướng dẫn sử dụng Loctite 660

1. Preparation – Cleaning

Use LOCTITE SF 790 to remove any old adhesive from parts. Use LOCTITE SF 7070 to degrease and clean surfaces prior to applying adhesive. For gaps larger than 0.5mm or worn out shafts, bearing seats or keyways, use LOCTITE metal-filled compounds to rebuild the surfaces.

2. Preparation – Activation

If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperature (below 5°C), use LOCTITE SF 7649 activator. Allow to dry.

3. Application – For Slip-Fitted Assemblies

Apply adhesive around the leading edge of the male component and the inside of the female component. Assemble parts with a rotating motion to ensure good coverage.  Wipe off excess adhesive.

4. Application – For Press-Fitted Assemblies

Apply 360 degree beads of adhesive to both bond surfaces at the leading edges of insertion or engagement, and assemble at high press-on rates.  Wipe off excess adhesive.

5. Application – For Shrink-Fitted Assemblies

Apply the adhesive onto the male component, heat the female component to cause expansion for free assembly. Assemble components and allow temperatures to equiliberiate. Wipe of excess adhesive.

6. Disassembly

Apply localized heat to approximately 500°F/260°C and disassemble while hot.
