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.
