GENERAL INFORMATION
For safe handling information on this product, consult the Safety
Data Sheet, (SDS).
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, Alumins, etc). Use
of visible light provides increased operator safety by eliminating
exposure to potentially harmful UV radiation. UV curing is
particularly advantageous where a very rapid cure of a section is
required.
2. For visible light curing, a light source with a peak output at 470
nm is most efficient. For example, a Luxor 2 or 3 curing lamp
delivers an output in excess of 150 mW/cm² at this wavelength,
curing in <1 minute to a depth of 12 mm unfilled and 6 mm in
filled grades.
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.
4. Packages removed from storage should be allowed to return to
ambient temperature before use.
5. A safe yellow light is recommended for visible light initiated
grades during handling prior to use. Dimmed light may be used if
the adhesive is only being handled for short periods of time.
6. This adhesive contains a secondary thermal cure initiator to allow
cure of bond areas shadowed from light.
7. The adhesive should be light cured first, followed by thermal cure
at 100°C for 1 hour. The minimum temperature for thermal cure
TDS LOCTITE ECCOBOND LUX A4083T, September-2014
is 85°C with the time extended to 2 hours.
