General Description
UVALAM UV-1306 is clear, one component, Medium viscosity UV adhesive.
UVALAM UV-1306 has shown excellent adhesion to a wide variety of substrates including glass, many plastics and most metals.
The thixotropic nature of UVALAM UV-1306 reduces the migration of liquid product after application to the substrate.
Recommend for
1/ It is primarily designed for bonding rigid or flexible PVC to polycarbonate where large gap filling capabilities and flexible joints are desired.
2/ It could be used for flexible bonds on stress-sensitive plastics.
3/ It could be used for bond on glass and ceramic materials.
4/it is especially suitable for bonding metal to soft/hard PVC (such as disposable medical equipment). It could meet ISO 10993-5 medical certification.

TYPICAL PROPERTIES OF UNCURED MATERIAL
Specific Gravity @ 25°C: 1.08
Refractive Index: 1.48
Viscosity, Brookfield - RVT, 25°C : Spindle 4, speed 20 rpm 5,000 mPa·s
TYPICAL CURING PERFORMANCE
UVALAM UV-1306 can be cured by exposure to UV and/or visible light of sufficient intensity.
To obtain full cure on surfaces exposed to air, radiation @ 220 to 260 nm is also required.
The speed 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.
Stress Cracking
Liquid adhesive is applied to a polycarbonate bar 6.4 cm by 13 mm by 3 mm which is then flexed to induce a known stress level.
Stress Cracking, ASTM D 3929, minutes:
7 N/mm² stress on bar: >15
12 N/mm² stress on bar: 13 to 14
Fixture Time
Fixture time is defined as the time to develop a shear strength of 0.1 N/mm².
UV Fixture Time, Glass microscope slides, seconds:
Black light, 6 mW/cm², measured @ 365 nm: ≤15 seconds
UV Fixture Time, Polycarbonate to PVC, seconds:
Metal halide bulb, 30 mW/cm², measured @ 365 nm: <5 seconds
Electrodeless,
50 mW/cm², measured @ 365 nm: <5 seconds
Electrodeless,
50 mW/cm², measured @ 365 nm: <5 seconds
Depth of Cure vs. Irradiance (365 nm)
The graph below shows the increase in depth of cure with time at 50mW/cm² - 100mW/cm² as measured from the thickness of the cured pellet formed in a 15mm diameter PTFE die.
Note: When exposed to a V Bulb at irradiances of 50 and 100mW/cm² for 30 seconds, a depth of cure greater than 13 mm was achieved. The performance for medium pressure Hg will be similar to Electrodeless system, H bulb.
