GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials
For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
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 Activator 7471™ or 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.
For Disassembly
1. Apply localized heat to the assembly to approximately
250 °C. Disassemble while hot.
For Cleanup
1. Cured product can be removed with a combination of
soaking in a Loctite solvent and mechanical abrasion
such as a wire brush.
