BRS-14320S
BRS-14320S: Difunctional Aliphatic Silicone Urethane Acrylate Oligomer
BRS-14320S is a difunctional oligomer that combines a robust silicone backbone into a urethane acrylate oligomer. The resulting product provides an unusual combination of desirable properties: softness, flexibility, and temperature resistance. BRS-14320S is a candidate for consideration in formulating 100% UV soft-touch coatings and also for electronics applications.
