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. To accelerate cure speed or where large gaps are present, use activator 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 part to produce a smooth, even film of material. If heating the hub for assembly, coat the pin. If the pin is to be cooled for assembly, coat the hub. If both heating and cooling is to be done, apply material to cooled part. Avoid condensation on cooled parts.
6. Parts should not be disturbed until sufficient handling strength is achieved.
LOCTITE 638 is intended for the bonding of cylindrical fitting components, significantly wherever bond gaps will approach zero.25 mm. the merchandise cures once confined within the absence of air between snug metal surfaces and prevents loosening and outpouring because of shock and vibration
