LOCTITE AA 3320 single part epoxy ultraviolet based adhesive which cures rapidly to form hard

LOCTITE® EA 3335™ is a single part epoxy based adhesive
which cures rapidly to form hard, translucent coatings when
exposed to medium intensity ultraviolet light of suitable
wavelength. LOCTITEAA 3320 exhibits low shrinkage and,
when cured, exhibits good thermal, water and chemical
resistance. LOCTITE 3320 is designed primarily for
bonding, coating and tacking applications on metal, plastics or
glass substrates. LOCTITE 3320 is suitable for
applications where low outgassing is required.

TYPICAL CURING PERFORMANCE
LOCTITE AA3320 can be cured by exposure to UV light
365 nm. To obtain full cure on exposed surfaces, irradiation at
220 to 260 nm is also required. Both speed and depth of cure
will depend upon the UV intensity and spectral distribution of
the light source, the exposure time and the light transmittance
of the substrates.
