Sample 400um film cured under 365nm LED, 500
mW/cm², 1500 mJ/cm²
Recommended UV Cure
Light Source and Condition:
UV LED
Wavelength, nm 365
Light Intensity, mW/cm² ≥500
UV Dosage, mJ/cm² ≥500
Depth of Cure
Depth of Cure, mm 2.3
Sample tested using Dymax 5000-EC UV
curing lamp, 100 mW/cm², 15 seconds.
LOCTITE ECCOBOND DS 3318BL 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).
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.
