UV/EB Oligomer
BR-541P
BR-541P Difunctional Aliphatic Polyether Urethane Acrylate
BR-541P is a difunctional aliphatic polyether urethane acrylate. This oligomer is a modified version of BR-541 meeting EU guidelines for lower inhibitor content. BR-541P demonstrates toughness and durability of a typical polyether urethane acrylate, along with improved adhesion to metals and nonporous substratres. It is an excellent choice to improve impact resistance in industrial coatings, and as a modifier resin in 3D printing applications.
