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).
Directions for use
1. Bond areas should be clean and free from grease. Clean
all surfaces with a Loctite
®
cleaning solvent and allow to
dry.
2. Loctite
®
Primer may be applied to the bond area. Avoid
applying excess Primer. Allow the Primer to dry.
3. LOCTITE
®
Activator may be used if necessary. Apply the
LOCTITE
®
Activator to one bond surface (do not apply
activator to the primed surface where Primer is also
used). Allow the Activator to dry.
4. Apply adhesive to one of the bond surfaces (do not apply
the adhesive to the activated surface). Do not use items
like tissue or a brush to spread the adhesive. Assemble
the parts within a few seconds. The parts should be
accurately located, as the short fixture time leaves little
opportunity for adjustment.
5. LOCTITE
®
Activator can be used to cure fillets of product
outside the bond area. Spray or drop the activator on the
excess product.
6. Bonds should be held fixed or clamped until adhesive has
fixtured.
7. Product should be allowed to develop full strength before
subjecting to any service loads (typically 24 to 72 hours
after assembly, depending on bond gap, materials and
ambient conditions).
