Résumé : |
This is an insight into how high intensity UV light sources will revolutionise curing technology.
It is interesting to note that though coatings have evolved and improved significantly over the last few decades, yielding faster cure, better properties, new pigment systems and gloss levels and safer materials, curing lamps has stayed basically the same. However, now that landscape is changing.
With the advent of new-intensity semiconductor UV light sources that can cure wide areas uniformly, radiation curing system customers now have access to clean, energy efficient, long life alternatives to traditional mercury lamp technology. As the new UV sources enter mass production, solid-state UV technology will revolutionise commercial processes like boat building, car repair, floor refinishing and other areas where a safe, portable easy-to-use UV source is critical.
The sources will also enable new applications for the first time. For example, low-temperature curing for temperature sensitive substrates, such as polyolefins is now enable, as is curing in areas where reduced green-house emissions and freedom from toxic waste generation are required. |
