المعالجة بالأشعة فوق البنفسجية هي عملية كيميائية ضوئية سريعة حيث تكون شدة الأشعة عالية الأشعة فوق البنفسجية 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.
