Fotopolimerización de acrilatos

n CH2=CHCOOR → [–CH2–CH(COOR)–]n

Descripción general

UV or visible light activates a photoinitiator that generates free radicals, which then initiate chain polymerization of acrylate monomers. The reaction is extremely fast (seconds to minutes) compared to thermal polymerization (hours). This enables rapid curing of coatings, adhesives, and 3D printing resins.

Ejemplo cotidiano

UV-cured gel nail polish at the nail salon hardens in 30 seconds under a UV lamp using this exact photopolymerization reaction.

Importancia industrial

Base del curado UV en recubrimientos, tintas de impresión 3D, adhesivos y lentes de contacto.
