TYPICAL CURING PERFORMANCE
乐泰® Product 3720 can be cured by irradiation with
ultraviolet of sufficient intensity. To obtain full cure on surfaces
exposed to air, the intensity of UV radiation at 220 to 260 nm
will accelerate the tack free cure of surface. The cure rate and
ultimate depth of cure will depend on light intensity, the spectral
distribution of the light source, the exposure time and the light
transmittance of the substrates. Following data are measured
at UV intensities of 100mW/cm2
using high pressure mercury
UV lamp
Storage
Maximum shelf life may be obtained when product is stored in
original containers, dry and dark location at a temperature
between 15
°C to 27
°C. Below 15
°C, the material may
crystallize. To restore fully, warm to 30
°C and shake or stir
