UV/EB Oligomer
BR-1041MB
BR-1041MB: Difunctional Aliphatic Polyether Urethane Methacrylate Oligomer
BR-1041MB is a biobased polyether urethane methacrylate oligomer with a substantial amount of biobased content and is tin-free. This is a harder version of BR-1043MB. This oligomer has a good balance of toughness and flexibility. It has the ability to adhere to a variety of plastic substrates. The biobased backbone, methacrylate functionality and tin-free nature make this an excellent choice for consumer applications with low irritancy.
