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.
3a. 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.
3b. 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.
3c. 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 equilibrate. Wipe of excess adhesive.
Apply localized heat to approximately 500°F/260°C; disassemble while hot. For corroded or seized parts, use LOCTITE® 8040™ Freeze and Release.
For manual assembly of adhesive the use of LOCTITE® Pro Pump or LOCTITE® Peristaltic Hand Pump is recommended to ensure a conistent application volume. For semi-automatic or fully-automated dispensing options contact our technical service team for advice.
