Typical Package
Application
LCD module assembly
LOCTITE ECCOBOND DS 3318BLX fast, UV curable material
is specially formulated for use in applications requiring lower
energy cure. It is designed for protection of COF (Chip-on-Film)
in LCD modules. Flexibility is a key characteristic of this
material, enabling stress absorption and providing extra
protection from cracking in functional testing.

LOCTITE ECCOBOND DS 3318BLX can be cured by irradiation
with ultraviolet and visible light as well as LED-UV light with single
wavelength distribution of sufficient intensity. Cure rate and depth of
cure depend on the intensity, spectral distribution of the light source,
exposure time and light transmittance of the substrate through which
the light must pass.

GENERAL INFORMATION
For safe handling information on this product, consult the Safety
Data Sheet, (SDS).
Not for product specifications
The technical data contained herein are intended as reference only.
Please contact your local quality department for assistance and
recommendations on specifications for this product.
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 application 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
transmission of the substrate through which the radiation must
pass.
5. Cooling should be provided for temperature sensitive substrates
such as thermoplastics.
6. Crystalline and semi-crystalline thermoplastics should be
checked for risk of stress cracking when exposed to liquid
adhesive.
7. Excess uncured adhesive can be wiped away with organic
solvent (e.g. Acetone).
8. Bonds should be allowed to cool before subjecting to any service
loads.
STORAGE:
Store product in the unopened container in a dry location.
Storage information may be indicated on the product container
labeling.
Optimal Storage: 18 to 25°C. Storage below 18°C
or above 25°C can adversely affect product properties.
