LOCTITE® AA 363 is a transparent, yellow, low viscosity, UV-cured, liquid acrylic urethane methacrylate adhesive. It is designed for high speed curing when used for shallow potting and thin-film encapsulating of electronic assemblies.

  • Designed for high speed curing in shallow potting and thin-film encapsulation
LOCTITE® AA 363™ is designed for shallow potting and
thin-film encapsulating of electronic assemblies.

This product is cured when exposed to UV radiation of
365nm. To obtain a full cure on surfaces exposed to air,
radiation at 250nm is also required. The speed of cure will
depend on the UV intensity as measured at the product
surface. Typical cure condition is 20-30 seconds at
100mW/cm² using a medium pressure, quartz envelope,
mercury vapor lamp.
Tack Free Time

Tack Free Time is the time required to achieve a tack free
Tack Free Time, seconds:
100 mW/cm², measured @ 365 nm 25
Fixture Time

Fixture time is defined as the time to develop a shear strength
of 0.1 N/mm².
UV Fixture Time, Glass microscope slides, seconds:
6 mW/cm², measured @ 365 nm ≤15
100 mW/cm², measured @ 365 nm 5
Depth of Cure

The graph below shows the increase in depth of cure with time
at 100mW/cm² as measured from the thickness of the cured
pellet formed in a 15mm diameter PTFE die

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. Recommended intensity for cure in bondline situation is 5
    mW/cm² minimum (measured at the bondline) with an
    exposure time of 4-5 times the fixture time at the same
  6. For dry curing of exposed surfaces, higher intensity UV is
    required (100 mW/cm²).
  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.
