LOCTITE ECCOBOND LUX AA50T die attach adhesive is formulated
to enhance productivity in the assembly of optical, fiber optic and
optoelectronic devices. This adhesive cures in seconds when exposed
to the appropriate intensity of visible (blue) or UV light. It also contains
a secondary thermal cure mechanism for applications with shadowed
areas.

GENERAL INFORMATION
For safe handling information on this product, consult the Safety
Data Sheet, (SDS).
THAWING:
1. Allow container to reach room temperature before use.
2. Safe yellow light is recommended for visible light initiated grades
during handling prior to curing. Dimmed light may be used if
adhesive is only being handled for short periods of time.
DIRECTIONS FOR USE
1. This adhesive is formulated to cure upon exposure to visible
(Blue) or UV light. Curing with visible light allows curing of highly
filled (up to 80% by weight) grades and curing through UV
opaque substrates (such as polycarbonate and alumins).
Additionally, use of visible light provides increased operator
safety by eliminatingexposure to potentially harmful UV
radiation. However, UV curing is particularly advantageous
where a rapid cure or curing of a section is required.
2. For visible light curing, a light source with a peak output at 470
nm is most important. For example, a Luxor 2 or 3 curing lamp
delivers an output in excess of 150 mW/cm‾³ at this wavelength,
curing in less than a minute to a depth of 6 mm.
3. For UV cure, a wide range of commercially available lamp
systems are available, permitting curing of bond profiles in
seconds coupled with a tack-free surface.
