LOCTITE AA 3525 is a clear, light-cured, acrylic-based adhesive that is toughened for high strength bonding. Although well suited to plastics and metals, it can also bond glass and ceramics. It offers low yellowing in a sunlit environment. The tack-free time is 10 secs, while the fixturing time is 5 secs. Depth of cure is >13 mm. Service temperature is up to 140°C.

• High strength, toughened
• Well suited to plastics and metals
• Ideal for electric motor balancing applications
• Low yellowing in sunlight

LOCTITE® AA 3525™ is suitable for bonding a wide variety of
materials. Cures fast to form clear, colorless bonds. When
cured, it offers excellent flexibility, toughness and durability to
moisture exposure. It is used to bond glass, metals and plastics
for industrial applications. LOCTITE® AA 3525™ is suitable for
use in electric motor balancing applications.

TYPICAL CURING PERFORMANCE

LOCTITE® AA 3525™ can be cured by exposure to UV and/or
visible light of sufficient intensity. The speed and depth of cure
will depend on the UV intensity measured at the product
surface.

Depth of Cure vs. Irradiance (365 nm)

Cure depth depends both on external factors including the type
of light source, light intensity and exposure time and on internal
factors including composition of the adhesive . The following
graphs show the effect of light source, light intensity and
exposure time on depth of cure for LOCTITE® AA 3525™

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
Safety Data Sheet (SDS).

Directions for use:

1. This product is light sensitive; exposure to daylight, UV
   light and artificial lighting should be kept to a minimum
   during storage and handling.
2. The product should be dispensed from applicators with
   black feedlines.
3. For best performance bond surfaces should be clean and
   free from grease.
4. Cure rate is dependent on lamp intensity, distance from
   light source, depth of cure needed or bondline gap and
   light transmittance of the substrate through which the
   radiation must pass.
5. Full cure is estimated to be four to five times the fixture
   time.
6. For dry curing of exposed surfaces, mercury arc ()
   or Electrodeless system, D or H bulbs are recommended.
7. Cooling should be provided for temperature sensitive
   substrates such as thermoplastics.
8. Plastic grades should be checked for risk of stress
   cracking when exposed to liquid adhesive.
9. Excess uncured adhesive can be wiped away with organic
   solvent (e.g. Acetone).
10. Bonds should be allowed to cool before subjecting to any
    service loads.
