LOCTITE® 638 - Bottle 10.0/case

Cleaning

• Use LOCTITE 7200 for easier removal of residues in case of old retaining adhesive
• It is recommended to use LOCTITE 7063 to degrease and clean surfaces prior to applying the adhesive
• For gaps larger than 0.5mm or worn out shafts, bearing seats or keyways, use LOCTITE metal-filled compounds 

Activation

If cure speed is too slow due to passive metals or low temperature (below 5°C), use activator LOCTITE 7240 or LOCTITE 7649 (see cure speed vs activator graph in the TDS). 

For slip fitted assemblies

Apply adhesive around the leading edge of the male component and the inside of the female component and use a rotating motion during assembly to ensure good coverage. 

For press fitted assemblies. 

Apply adhesive thoroughly to both bond surfaces and assemble at high press on rates. 

For shrink fitted assemblies.

Apply the adhesive onto the shaft, heat the collar to create enough clearance for free assembly.
