LS® Light-Sensitive Urethane Acrylates

LS® Light-Sensitive Urethane Acrylates

Aliphatic and aromatic urethane acrylates with photoinitiator grafted into the oligomer backbone. These custom oligomers can incorporate a variety of different Type I photoinitiators (PIs). Formulations can be designed to produce coatings, adhesives, and inks that exhibit little or no PI fragments and benzaldehyde. These LS® oligomers are suitable for FDA applications and offer benefits including reduced PI leaching, faster curing time, enhanced film properties, and more uniform cures.
