The polymerisation UV is belonging to the intensity of the UV lamp, to the distance from the UV light source, to the bondline gap and to the light transmittance of the substrate the light shall pass through. We recommend high inensity UV light sources with minimum radiation between 365 nm and 420 nm at 100mW/cm2. Curing time may vary according to adhesive gap.
