Bomar BR-571 is an aliphatic polyether urethane diacrylate with exceptionally low color. Based on a stable polyether backbone, BR-571 offers excellent physical properties in formulated films. While relatively high in neat viscosity, BR-571 reduces quickly with the addition of heat or monomer. Formulations using BR-571 often have a unique blend of toughness and flexibility. It is mainly used in Coatings for Wood, Pigmented Coatings and Rigid Plastic Topcoats.
