• Curing Type : Anaerobic with activator
• Application : Bonding

 

LOCTITE® AA 312 is a clear, amber, modified acrylic ester adhesive liquid typical applications include bonding dissimilar materials such as metals, glass or ceramics and where fast fixturing is required between close fitting parts. The product cures when confined between close fitting parts with the aid of Activator 736.

• Bonds dissimilar materials such as metals, glass or ceramics
• Used where fast fixturing is required between close fitting parts

 
LOCTITE® AA 312™ typical applications include bonding
dissimilar materials such as metals, glass or ceramics and
where fast fixturing is required between close fitting parts. The
product cures when confined between close fitting parts with
the aid of Activator 736™ or 734

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The graph
below shows the shear strength developed with time on grit
blasted steel lap shears and tested according to ISO 4587.
(Activator 736™ or 734™ applied to one surface).

Cure Speed vs. Bond Gap

Performance of this adhesive is adversly affected by increased
gap and therefore is not recommended in such applications.

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:

1. For best performance bond surfaces should be clean and
   free from grease.
2. To ensure a fast and reliable cure, Activator 736™ or
   734™ should be applied to one of the bond surfaces and
   the adhesive to the other surface. Parts should be
   assembled within 15 minutes.
3. Where bond gaps are large (up to a maximum of 0.125
   mm (0.005")), or faster cure speed is required, Activator
   736™ or 734™ should be applied to both surfaces. Parts
   should be assembled immediately (within 1 minute).
4. Excess adhesive can be wiped away with organic solvent.
5. Bond should be held clamped until adhesive has fixtured.
6. 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).
