BR-5413MB

BR-5413MB: Difunctional Aliphatic Polyether Urethane Methacrylate Oligomer

BR-5413MB is a difunctional aliphatic polyether urethane methacrylate. The oligomer has good balance of strength and impact resistance. Formulating with linear monofunctional monomers can yield improved flexibility. This oligomer is an excellent candidate to consider for use in impact-resistant coatings.
