A cura UV é um processo fotoquímico rápido onde a alta intensidade ultravioleta light is used to instantly cure or dry inks, coatings, and adhesives. The UV energy triggers photoinitiators within the liquid formulation, which then start a polymerization reaction that cross-links the molecules, converting the liquid into a solid in a fraction of a second. Cross-linked acrylic polymers have many applications, among them the sodium polyacrylate uses in diapers and soil conditioners. Whether a sodium polyacrylate biodegradable version can be made without losing absorbency is still a research question.
