LOCTITE® AA 326 is a yellow to amber, no-mix, structural and magnet bonder. It has good adhesion to different types of ferrites, a fixture time of 3 minutes and a shear strength of 15 N/mm². It can be used in temperatures up to +120°C. Requires LOCTITE SF 7649 to activate.

• Suited to magnet bonding
• Medium viscosity (thixotropic)
• Good adhesion to different types of ferrites
• Temperature resistant up to +120°C
• Fixture time is 3 min
• Shear strength is 15 N/mm²

 
LOCTITE® AA 326™ typical applications include bonding
ferrites to plated materials in electric motors, loudspeaker
hardware and jewelry where fast fixturing is required.

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 compared to different materials and
tested according to ISO 4587. (Activator 7649 applied to one
surface)

Cure Speed vs. Bond Gap

The rate of cure will depend on the bondline gap. The following
graph shows shear strength developed with time on grit blasted
steel lap shears at different controlled gaps and tested
according to ISO 4587. (Activator 7649™ applied to one
surface)

Cure Speed vs. Time, Temperature

The rate of cure will depend on the ambient temperature. The
graph below shows shear strength developed with time at 120
°C on grit blasted steel lap shears and tested according to ISO
4587.

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 7649™
   should be applied to one of the bond surfaces and the
   adhesive to the other surface. Parts should be assembled
   within 15 minutes.
3. The recommended bondline gap is 0.1 mm. Where bond
   gaps are large (up to a maximum of 0.5 mm), or faster
   cure speed is required, Activator 7649™ 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).
