UV/EB Oligomer
BR-543MB
BR-543MB: Difunctional Aliphatic Polyether Urethane Methacrylate Oligomer
BR-543MB is a difunctional, aliphatic polyether urethane methacrylate. BR-543MB is an excellent candidate to consider for use in cosmetic applications. As a primary oligomer, BR543MB offers excellent properties of adhesion and optical clarity. As a co-oligomer, BR-543MB can be used to improve an existing formulation’s glass adhesion. This product is listed in the INCI directory to meet cosmetic regulatory guidelines and has low skin sensitivity.
