乐泰 3131

乐泰 3131 dual cure adhesive is designed for use in the assembly of temperature sensitive electronic components. The maximum performance of this material is achieved by exposure to UV light of suffecient intensity, followed by thermal cure.

TYPICAL PROPERTIES OF UNCURED MATERIAL

Viscosity, HAAKE PK-100, Cone PK 1 2o, mPa·s (cP):

@ 25°C 14,000

Yield Point @ 25 °C, mPa·s (cP) 9,013

Thixotropic Index (2/20 s

-1 ) 1.6

Specific Gravity 1.23

Pot life @ 25 °C, days >14

Flash Point - See MSDS

TYPICAL CURING PERFORMANCE

Recommended UV Cure

Light Source and Condition:

Medium pressure mercury lamp

UV Wavelength, nm 220 to 260

Light Intensity, mW/cm2 100

UV Tack-Free Time, seconds 1

Recommended Heat Cure

30 minutes @ 60°C

25 minutes @ 70°C

20 minutes @ 80°C

The above cure profile is a guideline recommendation. Cure rate and ultimate depth of cure depend on light intensity, spectral distribution of light source, exposure time and the light transmittance of the substrate.

With all fast cure systems, the minimum required time for cure depends on the rate of heating. Cure rate depends on the mass of the material to be heated and intimate contact with the heat source. Use suggested cure conditions as general guidelines. Other cure conditions may yield satisfactory results.

TYPICAL PROPERTIES OF CURED MATERIAL
