LED option for adhesive curing - THE FIRST PRODUCT TO EMERGE FROM AN INNOVATIVE LED DEVELOPMENT PROGRAMME, A NEW LED CURING PENIS SET TO REVOLUTIONISE UV CURING

摘要

When photopolymer materials were first used as an alternative to solvent based adhesives, mercury lamps were the only UV light source capable of activating the photopolymer. Since then other bulb based lamps and microwave sources have been used, but they all have a number of disadvantages. They are expensive to operate, have a wasteful warm up period, deteriorate rapidly and have a comparatively short life. They also produce a light source that has a wide spectral bandwidth with only 5% of the light produced being used for curing, Industry is crying out for an LED light source alternative, LED light sources have a low cost of ownership, and produce an immediate and consistent light source over a long period with a lifetime of over 10,000 hours, They produce a light with an extremely narrow bandwidth and offer the flexibility that multiple peaks can be introduced if required.
