UV/EB Oligomer
BR-3042
BR-3042: Difunctional Aromatic Polyether Urethane Acrylate Oligomer
BR-3042 is an aromatic polyether urethane diacrylate designed for UV adhesive applications. Cured films of BR-3042 and monofunctional monomers result in soft, highly elongative, tacky systems ideal for use in UV pressure sensitive adhesives (PSA), or UV-curable laminating adhesives. Enhances adhesion and improves solvent resistance.
