With fast cure times, 3M Light cure Adhesives reduce processing time for many applications. And, because they do not require heat curing, they're especially ideal for bonding temperature-sensitive plastics. Low corrosion formulations are also available. Five of the new 3M Light Cure Adhesives may be cured with visible or UV light. The visible light cure adhesives provide a significant depth of cure - up to 4 inches deep, a plus for potting applications and thick section curing.
Visible light curing adhesives also cure through many translucent UV absorbing substrates.
The four UV light curing adhesives are nearly colourless and cure to tack-free surfaces under appropriate conditions. Exclusive to 3M, a special red-coloured Light Cured Adhesive contains a colour change indicator that changes from deep red to transparent yellow when exposed to either UV or visible light. Unlike conventional colourless adhesives, the red colour is easier to see and allows for precise hand application. This innovative adhesive undergoes the colour change within seconds. The new adhesives are solvent-free.
