BR-582E8

BR-582E8: 2.4 Functional Aliphatic Polyether Urethane Acrylate Oligomer

BR-582E8 is an aliphatic polyether urethane acrylate that provides a balance of toughness and flexibility. This oligomer is highly recommended for use in single-coat, flexible coatings on metal and plastic substrates. It is an excellent choice for impact and bend-resistant coatings. BR-582E8 also brings desirable weather resistance and low-yellowing properties to formulations utilizing it.
