Directions For Use: For Assembly
1. For best results, clean all surfaces (external and internal) with a LOCTITE® cleaning solvent and allow to dry
2. If the material is an inactive metal or the cure speed is too slow, spray with LOCTITE® SF 7471™ or LOCTITE® SF 7649™ and allow to dry
3. For Slip Fitted Assemblies, apply adhesive around the leading edge of the pin and the inside of the collar and use a rotating motion during assembly to ensure good coverage
4. For Press Fitted Assemblies, apply adhesive thoroughly to both bond surfaces and assemble at high press on rates
5. For Shrink Fitted Assemblies the adhesive should be coated onto the pin, the collar should then be heated to create sufficient clearance for free assembly
6. Parts should not be disturbed until sufficient handling strength is achieved
LOCTITE® 641 is designed for the bonding of cylindrical becoming parts, mainly the place disassembly is required for servicing operations. The product therapies when restricted in the absence of air between close-fitting metallic surfaces and prevents loosening and leakage due to shock and vibration. Ideal for components that want subsequent dismantling, i.e. retention of bearings on shafts and in housings.
