Directions for use:

For Assembly

• For best results, clean all surfaces (external and internal) with a cleaning solvent and allow solvent to evaporate.

• If the material is an inactive metal or the cure speed is too slow, spray with Activator 8071 or 8049 and allow drying.

• 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.

• For Press Fitted Assemblies, apply adhesive thoroughly to both bond surfaces and assemble at high press on rates.

• 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.

• Parts should not be disturbed until sufficient handling strength is achieved.

For Disassembly

• Apply localised heat to the assembly to approximately 250°C. Disassemble while hot.
