Multi-Pole LED UV Curing System


                                                                                                          The Multi-Pole LED UV Curing System emits a consistent and repeatable 2.5 W/cm squared @ 365nm at each pole.
                                                                                                          Unlike lamp technology there is no lamp or liquid light guide degradation or UV intensity variables throughout the
                                                                                                          individual poles. The 50,000 hour life of the LED and lack of liquid light guides and replacement lamps brings to the
                                                                                                          forefront of UV technology a zero level “cost of ownership”! The LED Multi-Pole system is equivalent to a
                                                                                                          10 W/cm squared lamp system using a 4 pole liquid light guide.

Cure time for Norland UV Adhesive

When bonding two surfaces with Norland UV Adhesive, the minimum full cure is estimated at 20 times the precure time using the same intensity of ultraviolet light. This is a general statement that works well in most applications.

The precure time is defined as the time it takes to initially set or gel the adhesive so that the two surfaces being bonded can no longer be moved. For example, a 15 second precure requires 5 minutes (15 seconds x 20 = 5 minutes) for full cure. Typical precure times will be from 5 seconds to 60 seconds depending on light intensity and adhesive formulation. When different light sources are used in production for the precure and the full cure, the precure time used in this calculation must be measured using the full cure light source.

Ultraviolet light is commonly divided into two regions. Short wave UV in the 190 to 320 nanometer range and long wave UV in the 320 to 400 nanometer range. The short wave UV is considered the most dangerous because it can easily damage the eye and can cause sun burn. No short wave UV light is emitted by any of the Norland UV light sources.

Long wave UV is considered relatively safe. There have been studies that show that high intensity long wave UV and bright visible light up to 500 nanometers can cause damage to the eyes with prolonged exposure. Because Norland UV Adhesives cure so quickly, our UV lights are low to medium intensity and are extremely safe to use with minimal precautions. Do not stare directly at the light and wear UV blocking eye protection. Indirect light from these units is considered relatively harmless.
